Overview

MRI is not often required in patients with bursitis. On MRI, bursitis is characterized by bursal fluid collection, subcutaneous edema and joint effusion. Due to the cost and time, the use of MRI is limited compere to ultrasound.^[1]^[2]

MRI

MRI is not often required in patients with bursitis. It is often reserved for the patients who are highly suspicious of other medical conditions such as tumors, ligament injures, and tendon injuries. On MRI, bursitis is characterized by:^[1]^[2]

Bursal fluid collection
- Hypointense on T1
- Hyperintense on T2
- Enhancement of bursal margins on (Gd)
Subcutaneous edema
Joint effusion

MRI may also be helpful in rolling out other joint conditions such as tumors, ligament injures, and tendon injuries. Olecranon bursitis
