magnetic resonance imaging (MRI), more often reveal erosive changes and abnormalities of the soft tissues, including capsular swelling, proliferative tenosynovitis, and synovial overgrowth

MRI is more sensitive than CT, and may reveal abnormalities that reflect focal neuropsychiatric lupus. However, MRI may also reveal white matter lesions or periventricular hyperintensities in patients with SLE who do not have neuropsychiatric symptoms. These white matter abnormalities may be difficult to interpret since they are present in 20 percent of the population younger than age 50, and in 90 percent of people older than age 70 .
MRI is the most useful neuroimaging study in patients with SLE, particularly in those with focal neurologic defects, seizures, chronic cognitive dysfunction, or the antiphospholipid syndrome and neurologic dysfunction; it is less useful in patients with affective disorders, confusional states, or headache. Although MRI frequently detects clinically silent lesions, we have found the correlation with neuropsychiatric symptoms to be quite good.
- Cine cardiac MR imaging is a useful noninvasive tool for evaluating abnormal flow patterns, ventricular dimensions, stroke volume, and regional myocardial function, but echocardiography is essential for evaluating valvular disease
- Avascular necrosis may be represented in gadolinium-enhanced MR imaging by lack of enhancement and devascularized areas
