- Male patients – Evidence of prostate, rectum or bladder pathology.
- Female patients – Evidence of ovarian, uterus, rectum or bladder pathology.

What is an MRI Scan?
- MRI (Magnetic Resonance Imaging) Scan uses strong magnetic fields and radio waves to detailed views of the organs, tissues and skeletal system.
- It is a non-invasive way to diagnose body structure and problems by producing high resolution images.
When is an MRI Scan performed?
- To detect brain and spine problems like strokes, tumors and aneurysms.
- To measure metabolical changes in the brain – Functional MRI.
- To analyse the disorders of eye and inner ear.
- To detect the problems with internal organs like Liver, Kidney, Pancreas.
- To measure the size of heart, thickness of heart walls and other structural changes.
- To analyse the bone and joint abnormalities, infections and tumors in soft tissues.
- To detect breast cancer.
How is MRI Scan different from CT Scan?
- MRI can show clearer differences between normal and abnormal tissue while CT Scans can sometimes provide more details about the hearts, lungs, pelvis, hips, reproductive systems, bladder and gastrointestinal tract.
- MRI Scans are safe and are commonly used for preventive checks.
- MRI Scans does not involves any radiation, while CT Scans involves radiation.
- MRI Scans takes more time than CT Scans and are generally more noisier.
What are the different types of MRI Scanners available?
- 1.5 Tesla MRI – These are conventional MRI machines.
- 3 Tesla MRI ( 3T MRI) – produces higher resolution images, are less noisy and are quicker than 1.5 Tesla MRI.
- Open or Upright MRI – for claustrophobic and bariatric patients. In this MRI machine a patient can stand or sit on a chair while having the Scan.
What types of MRI Scans can be performed?
Abdomen, Adrenal Glands, Angiography, Appendix, Back, Bile Ducts, BIliary Tract, Bladders, Blood Vessels, Bones, Bowel, Brain, Breast, Cervical Spine, Cervix, Chest, Cirrhosis, Crohn’s Disease, Disc, Enterography, Fallopian Tube, Fetus, Full Body, Gallbladder, Head, Heart, Joint, Kidney, Liver, Lumbar Spine, Lymph Nodes, MRA, MRE, Neck, Ovaries, Pancreas, Pelvis, Penis, Prostate, Scrotum, Shoulder, Small Bowel, Spine, Spleen, Testicles, Tumor, Ulcerative Colitis, Urethra, Uterus, Vasculitis, Vertebrae.
What is a Contrast?
- Sometimes a referring doctor may suggest a contrast injection that is used to enhance the images.
- Generally the contrast material used has a metal called Gadolinium.
How long does it take to do a MRI Scan?
Usually the Scans take between 20 to 60 minutes depending on the number of body parts covered in the Scan. Open/Upright MRI are longer in duration.
How soon are the reports available?
The MRI Scan images are available soon after the Scan. These images are studied by a medical practitioner (Radiologist) and the final report is produced and shared within 24 to 48 hours.
What are the risks and restrictions in MRI Scan?
- There are no know side effects of an MRI Scan.
- The Scans are not painful, but the contrast material can make you feel warm.
- There may be some guidelines about eating and drinking before the Scan.
- Patients are not given contrast if they have poor kidney function or renal impairment.
- Very rarely people may have allergies with the contrast material used.
- Patients who may be pregnant, need to check with their doctors before undergoing an MRI Scan.
- Metallic implants or joints can distort the images.
- Patients with artificial heart valves, pacemakers, metal clips, metal fragments, ear implants, chemotherapy and insulin pumps.
- Open or Upright MRI machines can normally bear weights of up to 400 lbs.
