Indications : MRI is indicated when there is a need for high spatial resolution of soft tissue .
Brain – most indications for imaging except in acute hemorrhage and calcification
Examines brain tissue and skull.
Great to obtain detailed anatomy of the soft tissue in the body.
Indications (study of / in suspicion of):
Stroke (particularly hyperacute)
Better than CT in demonstrating deep small lacunar lesions in the hemispheres and to visualize the posterior fossa
Contrast (Gadolinium) can be given to better define and characterize lesions.
Spine – most indications for imaging of the spine . MRI of the spine can help detect herniated or bulging discs, arthritic changes, tumors and other lesions.
Breast – MRI’s ability to differentiate water, fat, and silicone makes it the procedure of choice for evaluating silicone breast implants , implant rupture or residual silicone from removed implants.
Musculoskeletal : MRI of the joints and soft tissue can help detect torn ligaments, torn cartilage, edema (swelling), arthritic changes, tumors, lesions, osteomyelitis, and structural changes.
Abdomen: Only when CT is contraindicated
Cardiac : indications for a MRI of the heart include congenital and acquired heart disease.
Thorax – CT is generally preferred , however MRA may be used for diseases of the aorta.
