Overview
Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan.
City X-Ray & Scan Clinic provides advanced 3 Tesla MRI scans at the lowest prices.
Why is an MRI done?
Magnetic resonance imaging (MRI) is done for many reasons. It is used to find problems such as tumors, bleeding, injury, blood vessel diseases, or infection. Open & Wide Bore MRI also may be done to provide more information about a problem seen on an X-ray, ultrasound scan, or CT scan.

MRI of the brain and spinal cord
MRI is the most frequently used imaging test of the brain and spinal cord. It’s often performed to help diagnose:
- Aneurysms
- Disorders of the eye and inner ear
- Multiple sclerosis
- Spinal cord injuries
- Stroke
- Tumors
Functional MRI of the brain (fMRI) can be used to identify important language and movement control areas in the brain in people who are being considered for brain surgery.
MRI of the heart and blood vessels
An MRI that focuses on the heart or blood vessels can assess:
- The size and function of the heart’s chambers
- Thickness and movement of the walls of the heart
- The extent of damage caused by heart attack or heart disease
- Structural problems in the aorta, such as aneurysms or dissections
- The buildup of plaques and blockages in the blood vessels
MRI of other internal organs
An MRI may be used to check for tumors or other abnormalities of many organs in the body, including the:
- Liver
- Kidneys
- Spleen
- Pancreas
- Uterus
- Ovaries
- Prostate
- Testicles
MRI of bones and joints
MRI may be used to help evaluate:
- Joint disorders, such as arthritis
- Joint abnormalities caused by traumatic or repetitive injuries
- Bone infections
- Tumors of the bones and soft tissues
Types of MRI
There are typically three types of MRI scans available:-
In such MRI scans, the patient lies on a table that goes inside a narrow tube and in such MRI the patient might get uncomfortable especially people who are claustophobic (fear of closed spaces) but it 4provides best images
In such MRI scan the patient lies down and the machine is open hence no discomfort but the quality of images in such MRI is not as good as in the case of closed MRI scan.Usually obese people prefer such open MRI Scan
In such MRI scan the patient can lie down or can even stand hence it offers comfort but the image quality is not as such as closed MRI scan
MRI Services available at City X-Ray
Diffusion MRI
Diffusion MRI is an imaging method that uses the Brownian motion of water molecules to generate contrast in MR images. It allows the mapping of the diffusion process of molecules, mainly water, in biological tissues, in vivo and non-invasively.
It is useful in the investigation of other brain disorders such as epilepsy, multiple sclerosis, brain abscesses, brain tumors, mild traumatic brain injury, and hypertensive encephalopathy
MR Angiography
MR angiography (MRA) uses a powerful magnetic field, radio waves and a computer to evaluate blood vessels and help identify abnormalities. This exam does not use ionizing radiation and may require an injection of a contrast material called gadolinium, which is less likely to cause an allergic reaction than iodinated contrast material.
MR Spectroscopy (MRS)
Magnetic Resonance (MR) spectroscopy is a noninvasive diagnostic test for measuring biochemical changes in the brain, especially the presence of tumors. While magnetic resonance imaging (MRI) identifies the anatomical location of a tumor, MR spectroscopy compares the chemical composition of normal brain tissue with abnormal tumor tissue. This test can also be used to detect tissue changes in stroke and epilepsy.
MR Defecography
Magnetic resonance (MR) defecography is a noninvasive test that uses magnetic resonance imaging to obtain images at various stages of defecation to evaluate how well the pelvic muscles are working and provide insight into rectal function. It is used to help determine the cause of fecal incontinence, constipation, and other conditions such as pelvic organ prolapse that may interfere with a person’s ability to pass stool.
MR Mammography
Breast MRI (magnetic resonance imaging), also known as magnetic resonance mammography, is a noninvasive technique for imaging the breasts. It creates high-quality images of the breasts and has better sensitivity and specificity for detection of breast cancer than the other currently available technologies. Breast MRI is also used in evaluation of integrity of breast implants.
How is an MRI Scan done?
- You are required to wear a gown which should not have any metal button, zips or any other metal bearings as it causes blurring of the image.
- You may be asked not to eat for 4-6 hours before going for MRI.
- Before going for the MRI scan the doctor may ask you if you have any kidney problems, whether you are on dialysis.
- The doctor also asks you about any metal implants you have in the body like artificial valves, inner ear implants, artificial joints etc. as any kind of metal inside the body can cause problems with the clarity of images and provide blurred images.
- Remove jewellery, spectacles, credit cards, hairpins, metal zippers, pins, watches or any other kind of metal item before going for MRI scan.
- You may also be asked if you are claustrophobic (fear of closed spaces).
- A contrast dye called gandolinium is injected for better images.
- You must also inform the doctor if you are pregnant as MRI should not be done in 1st 3 months of pregnancy.
- Moving during the scan can cause blurring of the image so you are asked to stay still.
Advantages of a MRI
- MRI scan is as such better than X-Ray and CT Scan as it does not use ionising radiations which can prove to be harmful.
- No side effects.
Quite Suite
MRI of liver & Myocardium for Iron Estimation
MRI of liver & Myocardium is done to estimate iron deposition in patients of Thalassemia who need repeated blood transfusions.
MR Neurography
MR Neurography is a recent application in which MR of nerves of different parts of body is done and it helps in explaining the disease & symptoms of the patient released to neurological problems.
Fetal MRI
Fetal MRI is done in pregnant patients in 2nd trimester onwards to evaluate fetuses with congenital anomalies diagnosed in ultrasound.
