Introduction

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):

Tumor

Metastatic disease

Stroke (particularly hyperacute)

Better than CT in demonstrating deep small lacunar lesions in the hemispheres and to visualize the posterior fossa

Infection

Multiple sclerosis

Post-surgical evaluation

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.
