Overview

MRI is not often required in patients with bursitis. Due to the requisite cost and time input, the use of MRI is limited compared to ultrasound. MRI is often reserved for patients for whom there is reason to suspect the presence of other medical conditions such as tumors, ligamentous injures, and tendon injuries. On MRI, bursitis is characterized by bursal fluid collection, subcutaneous edema, and joint effusion.^[1]^[2]

- Hypointense on T1
- Hyperintense on T2
- Enhancement of bursal margins on (Gd)
Subcutaneous edema
