MRI scans are used for capturing high-resolution images of your internal structure. Find out how it helps as the Department of Diagnostic Radiology at Singapore General Hospital shares.
What is an MRI scan?
Your doctor may request a magnetic resonance imaging (MRI) scan to detect or diagnose a range of medical conditions.
Unlike a computed tomography scan (CT scan) which uses ionising radiation, an MRI scan uses a magnetic field, radio waves and computer technology to capture high-resolution images of the body’s internal structure.
“An MRI scan is a safe and painless diagnostic imaging tool for capturing accurate and detailed images of body parts that sometimes cannot be seen by standard x-rays and CT scans” says

How can an MRI scan help?
Your doctor may order an MRI scan for the brain, spine, chest, heart and aorta, bones and joints, abdomen and pelvis.
An MRI scan can help to:
- Locate any tumour, infection or swelling in the brain and spinal cord.
- Check for cancerous or abnormal growths in internal organs, in the abdomen and pelvis such as the liver, pancreas, kidneys, prostate, uterus and ovaries.
- Visualise torn tendons and ligaments in joints, detect disc disorders such as herniated discs and bone tumours.
- Detect strokes and other vascular diseases of the brain such as aneurysms.
