The most common type of MRI is a Magnetic Resonance Angiography (MRA). This type of scan uses magnetic fields and radio waves to visualize blood vessels in the body. It can be used to diagnose vascular diseases, such as aneurysms and stenosis. 2 A Computed Tomography (CT) Scan is another popular type of MRI. CT scans use x-rays to create cross-sectional images of the body. These images are then reconstructed into detailed 3D images that doctors can view on a computer screen. CT scans are often used for cancer staging and diagnosis.3 A Magnetic Resonance Spectroscopy (MRS) is an MRI technique that measures the chemical composition of tissues. It can be used to detect certain brain disorders, such as tumors and strokes.
