Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that uses strong magnetic fields, radio waves, and a computer to generate detailed images of organs and tissues inside the body.

MRI provides high-resolution, cross-sectional images in multiple planes (axial, sagittal, and coronal) of soft tissues such as the brain, muscles, heart, joints, and spine. It is often used to diagnose abnormalities like tumors, inflammation, and structural problems in organs and tissues. MRI scans are widely used for neurological, musculoskeletal, cardiovascular, and oncological conditions.

Here are some common types as below:

  • Functional MRI
  • Magnetic Resonance Angiography
  • Cardiac MRI
  • Diffusion MRI
  • MR Spectroscopy
  • Breast MRI

Following are the procedure steps:

Preparation: The patient may be asked to avoid eating or drinking before the scan. Any metal objects (jewelry, watches, hairpins, etc.) must be removed. The patient is asked to change into a hospital gown if needed. For some types of MRI (e.g., contrast MRI), a contrast dye (usually gadolinium-based) may be injected into the bloodstream to improve image clarity.

Positioning: The patient lies down on a movable table that slides into the MRI machine.

Cushions or straps may be used to help the patient stay still during the scan. Earplugs or headphones are provided to protect against loud noises from the machine.

Scanning: The MRI scanner creates a magnetic field around the patient, and radio waves are used to align hydrogen atoms in the body. These atoms emit signals that are detected and converted into images by a computer. The process is usually painless, though some patients may feel claustrophobic in the MRI machine. The scan typically takes between 30 minutes to over an hour, depending on the type of scan.

After the Scan: If contrast dye was used, the patient may be monitored for a short time to ensure no allergic reaction occurs. The images are then reviewed by a radiologist, who prepares a report for the referring doctor. Normal activities can usually be resumed immediately unless sedation was used.
