Frequently Asked Questions
Magnetic resonance imaging (MRI) is a non-invasive imaging technique that produces detailed
images of any part of the body. The tool can be used for imaging soft tissues such as the heart,
brain, muscles and finding out tumors in the body.
Most MRI procedures usually take 15 to 90 minutes to complete, but the duration will depend on
the part of your body being scanned and the number of images being taken.
While x-rays and CT scan both use a small dose of ionizing radiation to produce images, an MRI scan uses powerful magnets and radio waves to make images of the body.
The MRI scanner is a large cylinderical shaped machine, which is open at both ends. The tunnel remains OPEN and you are NEVER totally enclosed. You will normally lie flat on your back and be moved into the tunnel on a sliding couch. The part of your body, which is to be scanned, will be in the centre of the tunnel.
Some MRI tests require contrast. The contrast medium provides enhanced image quality and helps health professionals to diagnose medical conditions in a better way. The contrasting agent is a clear fluid usually injected into a vein in the arm immediately before the scan. You will feel no ill effects from the injection.
Magnetic resonance imaging (MRI) is a safe procedure and most people can take up this test. However, in some circumstances, an MRI scan may not be recommended. Please tell the MRI department if you have or think you have any metal in your body or if you are pregnant.
Although there are no known effects, it is advisable not to scan pregnant women. However, in certain critical cases, it may be necessary to be scanned during pregnancy when a more invasive diagnostic test would otherwise have to be performed. Please consult your doctor before getting an MRI scan done.
A 3T scanner is twice the strength of a 1.5T scanner. A 3T scan helps deliver enhanced imaging and speed as compared to 1.5T scan.
A CT scan uses X-rays and a computer to create detailed images of organs, bones and other tissues in cross section like slices. It provides more detail than a regular X-ray.
The entire procedure usually takes between 0 to 60 minutes, depending on what part of the body is being scanned.
After the scan is finished, a radioligist will study your images and dictate the findings. Your physician will then review the report and discuss it with you.
It helps in enhancing all of the vascular structures on the images (i.e. liver, pancreas, kidneys).
CT scan is a safe imaging test. However, it exposes you to a small dose of radiation. For most people, such a small potential risk far outweighs the benefits, in terms of saving your life.
Both CT scans and MRIs are used to view internal structures. While a CT scan uses X-rays, the MRI scan makes use of strong magnetic field and radio waves.
A positron emission tomography (PET) is a powerful imaging technique that provides details about how tissues and organs are functioning. The scan produces 3-dimensional images of the inside of the body. It helps doctors diagnose various illnesses, injuries, and disorders.
PET scans help check any abnormal cell activity rather than internal structures. It can spot symptoms of certain diseases that other imaging techniques cannot make out. It is often ordered when your doctor either suspects cancer or that a cancer may have spread. It is also used to determine the damage following a heart attack or stroke, and to monitor your response to neurological, cardiovascular or cancer treatments.
During a PET-CT scan, a radioactive form of glucose (sugar), also called a radiotracer, is injected into the vein of your arm. The radiotracer gets absorbed by the body and then a PET scan and CT scan is performed to get a complete picture of what is going on.
It usually takes around 30-90 minutes for the radiotracer to get to the body parts that will be scanned. After that, the scan can take somewhere around 20-45 minutes. The time taken will depend on the number of body parts being scanned. You will be asked to remain still for the length of the exam.
The patient can leave the PET centre immediately unless he is feeling tired after fasting so long. It is important to drink loads of water throughout the day to flush out the radioactive chemical from within the body.
A PET Scan helps in differentiating benign and malignant tumors, and allows accurate staging. Both CT and MRI allow to view internal body structures.
A PET scan is a painless imaging test and has few risks. Since a PET scan uses a radiotracer, there is a risk of radiation exposure. Women should tell the radiologist if they are breastfeeding or pregnant.
Since PET-CT Scan is a detailed investigation, our team of doctors will be reviewing and reporting your study within 24-48 working hours.
A PET-MRI scan combines the anatomic imaging of MRI (magnetic resonance imaging) with the functional imaging of PET (positron emission tomography) in one session. It creates a very detailed 3D image of the inside of the body.
A PET-MRI scan is done to know the location of cancer and to find out how big it is. It is also used in various neurological and cardiac conditions. The scan is helpful in planning the treatment and checking out how well the treatment is working. For instance, if an individual is having seizures that don’t respond to medicines, a PET-MRI may be advised to evaluate if surgery could help.
For the PET scan, a small amount of a radioactice tracer is injected intravenously. The PET scan shows up areas of the body where cells are more active. At the same time, MRI scan uses a strong magnetic field and radio waves to produce detailed pictures.
Depending on the area of the body being scanned and the number of scans ordered by the doctor, the procedure usually takes around 2-3 hours.
It is a safe test. Since no X-rays are used, there’s no radiation exposure from the MRI.
It is a state-of-the-art PET CT scanner, providing highly detailed images.
In a PET CT scan, motion (like breathing and beating of the heart) can cause blurring or reduced resolution, thus causing reduced lesion detectability. This makes it a challenge to detect the smallest tumor. A motion-free PET CT scan helps provide better image quality and improved lesion localization.
A gamma camera is a nuclear medicine imaging machnine. It records the energy emission from the radiotracer in the body and converts it into an image. Its radiation detectors are called gamma camera heads. It provides detailed information about the functioning of various organs such as thyroid, lungs, heart, parathyroids, kidneys, liver, adrenals, etc. They are used in the diagnosis of health conditions and follow-up treatment.
A dual-head camera is equipped with two heads capable of detecting the presence of radiation. Two opposing detectors help pick lesions that may have been picked out of the scope of a single detector. Two heads also provide better localization of a lesion’s depth and estimate its size.
It is an imaging test that combines images from a positron emission tomography (PET) scan and a magnetic resonance imaging (MRI) scan. By combining the excellent tissue differentiation of MR with the sensitivity of PET, the scan provides highly detailed images of the inside of the body.
An MRI scan uses a strong magnetic field and radio waves to deliver highly detailed images of the inside of the body. A Positron Emission Tomography (PET) scan uses a special dye that contains a radioactive tracer to see how your organs and other tissues are working inside the body. It helps diagnose disorders, including cancer, and to plan radiation therapy.
More accurate diagnosis: PET/MRI scans of the brain are better at detecting abnormal findings than PET-CT.
Less radiation: As compared to PET-CT, a PET-MRI scan exposes patients to about 50 per less radiation.
Convenience of two scans in one: You don’t need to take separate appointments for both scans.
Your scan usually takes 60 to 90 minutes.
An ultrasound scan, also called sonography, is a diagnostic tool that uses high-frequency sound waves to create live images of the inside of the body’s structures. The images allow the doctor to see and determine any abnormality or health-related issue with the body’s organs, tissues, and vessels.
During an ultrasound exam, a transducer (a wand-like hand-held device) sends sound waves within the body. The sound waves come into contact with tissues, bones and body fluids (such as blood), and bounce back, like echoes. These echoes are received by the transducer and then turned into images. The denser the tissue the more sound waves will bounce back.
There are no known harmful effects of these scans. There has been widespread usage of diagnostic ultrasound in pregnancy. A trained healthcare professional, also known as a sonographer, will follow the guidelines to ensure that you and your baby are safe. A prudent approach is to use the sound waves at the lowest level and for the shortest time.
It is a non-invasive procedure that has been used extensively in the female reproductive organs, kidneys, liver, gallbladder, and for cardiac diagnosis. Ultrasound imaging is also used for other areas, such as the brain, eyes, thyroid, breast, prostate, and testicles.
On average, an ultrasound takes around 20 to 40 minutes, depending on the part of your body being scanned.
A full bladder moves the organs and allows the sonographer to see with much more clarity.
At least 8 to 12 hours of fasting is required before an abdominal ultrasound. This is because food and liquid in your stomach can make it difficult for the sonographer to get clear images of the structures in your abdomen.
An X-ray is a medical imaging technique that use a small amount of ionizing radiation to produce images of a body’s internal structures.
Your doctor can order an X-ray for checking fractures (broken bones), dislocated joints, arthritis, abdominal pain, and tooth decay. It can also be used to check your lungs for signs of pneumonia or tuberculosis, enlarged heart, blocked blood vessels, and digestive tract problems.
It usually takes around 10-15 minutes to complete. However, the time taken will depend on the number of body parts being scanned and your mobility. X-rays of people with disabilities and children also take longer.
The amount of radiation you receive from a single x-ray is very low. Radiologists are well trained to keep radiation exposure to a minimum while ensuring optimum diagnostic accuracy.
Female patients who are pregnant, must inform the referring doctor, technologist or radiologist prior to having an x-ray.
Certain X-Rays require fasting. You need to check out the specific test for further preparations. Please notify the radiology department if:
you had a similar X-Ray recently
the patient is a women who is or might be pregnant
X-ray is an easy to perform test and takes very little time to complete, meaning it is particularly useful in emergency diagnosis and treatment.
Some X-rays involves adminsitration of a special dye, called a contrast medium. The medium changes the way soft tissues and other structures appear on the scan – meaning your doctor can see them in more detail.
After collecting the X-ray images, the radialogist may ask you to change back into your regular clothes. Depending on your condition, you may be asked to rest or take up your normal activities. If you received a contrast dye before the X-ray, drink plenty of water to flush the contrast material from your body.
DEXA - also called “dual-energy X-ray absorptiometry,” is a medical imaging test that uses low levels of X-rays to measure how dense your bones are.
DEXA scan uses X-rays to determine the distribution of fat, muscle, water and bone in the body. It works by passing two low-dose x-ray beams at different energy levels through the body. The machine comes with special software that measures bone density.
This bone density testing is used by doctors to find out any decrease in bone density before you break a bone. It is also used to confirm a diagnosis of osteoporosis.
These scans are safe. The amount of radiation used in these scans is very low.
During the test, you should wear comfortable clothing which is without metal buttons and zippers.
You will be asked to lie on your back on a padded table. A technician may place a wedge under your knees to position your hip or flatten your spine. You have to stay very still while the imaging arm moves slowly across your body. The entire process is completed within a few minutes.
Mammography uses a low-dose x-ray system to see inside the breasts. Mammography examination, also called a mammogram, aids in the early detection and diagnosis of breast diseases in women.
Your doctor will ask you to take the test depending on your present health status, family history and other risk factors. Mammograms are recommended as a screening test to check for breast cancer and as a diagnostic test to check for lumps or other symptoms.
You will be asked to stand in front of a special X-ray machine. A technician will lower a plastic plate that presses down on one of your breasts. This will put some pressure on your breast. The plates flatten your breast to view the tissues. It helps find out tumors or other signs of breast cancer.
The pressure of the plates on the breasts may be uncomfortable or even painful for some women. The breast compression process only takes a few minutes.
You can eat, drink, and take medications. On the day of the test, you should not wear body powder, cream, lotion or deodorant on your chest as these products can show on the X-ray.
Due to compression, there may be some temporary changes in skin color or mild aching. You can resume your regular activities after the test.
If the results from your mammogram are abnormal, you may be asked for some follow-up tests to check whether or not the finding is breast cancer.
Cardiac screening includes a range of tests to assess your cardiovascular health and risk factors.
The tests that are performed during cardiac screening include Electrocardiogram (ECG), Echocardiogram, Cardiac MRI, blood pressure, blood cholesterol, and measuring body weight/BMI. Each of these tests helps to detect various risk factors or signs of a heart disease.
Cardiac screening is particularly important for people who have any risk factors for a heart disease. Some of them include: being overweight, smoking, drinking, a family history of heart disease, a sedentary lifestyle, or having a condition such as high blood pressure. It is also important if you have symptoms such as chest pain, breath shortness, or experience dizziness or fainting spells.
It becomes crucial for men aged 40 years and above, and women aged 50 years and above, to be screened regularly. Based on your medical history, you should ask your doctor how often should you go for regular heart screenings.
A neurological exam, also called a neuro exam, provides the physician with valuable insight into a person's nervous system - comprising of brain, spinal cord, and nerves from these areas.
It is helpful in finding out any neurologic diseases and find out disorders that may negatively impact the quality of life. Some of the symptoms caused by neurological diseases include headaches, blurry vision, fatigue, dizziness or speech problems, varying degrees of paralysis in a leg or arm, muscle weakness, and unusual sensations or confusion.
There are no special requirements for a neurological examination. Your normal movements and reactions will help the doctors to evaluate your condition correctly.
There is no risk associated with this test.
An electroencephalogram Test ( EEG Test ) is a noninvasive test that evaluates the electrical activity in your brain. The test helps find out potential problems associated with this activity. The EEG test is generally used to help diagnose conditions such as seizures, epilepsy, head injuries, dizziness, headaches, and sleeping problems. In this test, small metal discs called electrodes are attached to your scalp with wires. The eletrodes analyse the electric impulses and then transfer them to a computer to record the results.
Also called a nerve conduction study (NCS), the test evaluates how fast an electric impulse moves through a nerve. The NCV test is used to asess nerve damage and dysfunction. In this test, your nerve is stimulated, usually with electrode patches attached to your skin over the never. The nerve conduction velocity (speed) is determined by calculating the distance between electrodes and the time it takes for electrical impulses to travel between electrodes.
It is method for diagnosing peripheral nervous system disorders, including chronic pain and pain related to diseases like diabetes and CRPS. The QST determines the sensation and pain thresholds for cold and warm temperatures, and the vibration sensation threshold by stimulating the skin and comparing the results to normative values built in the software.
Autonomic testing, also called autonomic response testing, evaluates the functioning of your autonomic nervous system (ANS). Your ANS helps control blood pressure, heart rate, sweating and digestion. The testing can show which part of the ANS has been affected and to what extent. It allows your healthcare provider to develop an effective treatment strategy to deal with it.
CBCT is a medical imaging technique that is particularly used in dental imaging. It uses a cone-shaped x-ray beam that produces high-quality and accurate 3-D images of your teeth and jaws.
It is an extensively used test in accurate placement of dental implants; evaluation of the jaw, nerve canal, sinuses, and nasal cavity; determining tooth orientation and for reconstruction surgery.
It looks similar to a traditional panoramic machine. Patients can either stand or sit at a table. During the scan, the scanner rotates around the patient’s head in a complete 360-degree rotation and takes around 150-200 images to create a single 3D image.
A single CBCT scan usually takes around 12 – 28 seconds (depending on the area to be scanned). This means it is only used in cases where detailed imaging is required.
While a CBCT test exposes a patient to less radiation than a CT, the radiation is more than a traditional dental X-ray.
As against a standard X-ray, the scan provides images in high-quality and greater detail. It provides images of both the soft tissues and bone. Due to faster scan time, everything gets scanned in a single rotation.
