MRI or Magnetic Resonance Imaging is a non-invasive diagnostic scan. MRI uses a magnetic field and radio frequency waves to produce detailed anatomical images in various planes without having to move the patient. MRI scans image different types of organ tissue without ionizing radiation making it safe. MRI is also used to obtain specific diagnostic information that may not have been provided by other imaging modalities such as ultrasound, traditional X-ray and computed tomography (CT). Usually a MRI scan takes approximately 15-30 minutes. The duration may vary depending upon a specific type of exam.
Depending upon the type of scan and the reason for performing the scan, sometimes a solution called “contrast” may need to be injected to the patient undergoing MRI scan. The images obtained after administering contrast provide additional valuable information about the body part being scanned. It is important to inform the scan technologist beforehand in case the patient has any allergies, especially to iodine-based products.
The most commonly performed MRI scans are
- MRI Scan of Brain
- MRI Scan of Spine
- MRI Scan of Joints
- MR Angiography especially of the brain and neck
The primary reasons for conducting a MRI scan are
- All brain pathologies such as stroke, bleeds, tumors and degenerative diseases. Other areas are hearing problems and Vertigo.
- Innumerable spine problems involving the vertebrae or the spinal cord. MRI is the only modality which images the cord and abnormalities within it.
- Joint diseases-, especially for cartilage and ligament problems. This includes large as well as small joints.
Musculoskeletal system for imaging of muscles, ligaments, tendons and non-cortical bone.
- MR Angiography for arterial and venous diseases.
- For Liver diseases
