The Different Types Of MRI Scans

The Different Types Of MRI Scans

MRI scans, or Magnetic Resonance Imaging, is a type of diagnostic imaging test that can produce images of the body’s soft tissues and nervous system. MRIs use radio and magnetic waves to create these images rather than radiation. Whether you need an MRI for injury or illness, your doctor should walk you through the type that would be best for your condition.

Functional MRI

A Functional MRI measures blood flow to your brain and tests brain activity. This type of scan will light up when certain areas of the brain are activated. The images are used to predict or diagnose a stroke, assess a brain injury, and test for dementia or Alzheimer’s. Functional MRIs can also be used for brain mapping. Brain mapping is used to detect epilepsy or tumors and is essential for brain surgery.

Cardiac MRI

A Cardiac MRI takes detailed images of the heart and blood vessels, and allows doctors to see how your circulatory system is functioning. Your doctor will order a Cardiac MRI to detect blockages or see if there are issues with the structure of the heart. This type of MRI is also used to see damage from a heart attack, problems with the aorta, and detect tumors in the heart.

Contrast MRI

If your doctor orders a Contrast MRI, it means you will be injected with a dye that will improve the visibility of your internal structures and show up clearly in the images. Patients who cannot tolerate the dye can get Non-Contrast MRAs (Magnetic Resonance Angiography). This eliminates the need for the dye without compromising on clear imaging.

Open and Closed MRI

MRIs are usually thought to be closed in and quite claustrophobic, but with the technology now, patients can opt for Open MRIs. Patients who are obese, claustrophobic, or experience PTSD will feel more comfortable in an Open MRI.

Musculoskeletal MRI

Musculoskeletal MRIs are most common for assessing injuries or illnesses that affect the bones, joints, and muscles. This type of MRI can detect damage to the joints like tears in the cartilage, ligaments, or tendons due to injury or arthritis. It is also used to detect spinal injuries such as spinal fractures or herniated discs. Musculoskeletal MRIs are useful to detect hairline fractures which can be difficult to see in an X-Ray.
