Overview
Joint and synovial evaluation
Reveal erosive changes and abnormalities of the soft tissues more often, including:
- Capsular swelling
- Proliferative tenosynovitis
- Synovial overgrowth
Neurological evaluation
MRI is more sensitive than CT, and may reveal the following abnormalities:
- Focal neurological defects
- White matter lesions
- Periventricular hyperintensities
- Detects clinically silent lesions
Cardialogical evaluation
- Cine cardiac MR imaging as an noninvasive tool for evaluating
- Abnormal flow patterns
- Ventricular dimensions
- Stroke volume
- Regional myocardial function
Bone evaluation
- Avascular necrosis (AVN)
- Lack of enhancement and devascularized areas on gadolinium-enhanced MR imaging
- Bone marrow edema on MRI with
- Low-signal-intensity marginal areas on standard spin-echo T1- and T2-weighted images
- Intermediate to high signal intensity inside bone tissue on T2-weighted images, producing a line of low signal intensity with an adjacent high-signal-intensity line
- High signal intensity on T2-weighted images due to subchondral fractures that may be accompanied by fluid signal intensity or edema
- Low signal intensity on T2-weighted images due to collapse of the articular surface
- Early or subtle insufficiency fractures especially on T2-weighted MR imaging
- In characteristic stress locations insufficiency fractures may appear as areas of high signal intensity due to bone marrow edema
