Can an ultrasound show inflammation?

Both ultrasound and MRI can detect synovitis, inflammation of the lining of the joints, and tendon abnormalities. In addition, MRI detects areas of increased fluid (edema) in bone marrow that is a predictor for the development of bony erosions.

What does a tumor look like on an ultrasound?

For example, most waves pass through a fluid-filled cyst and send back very few or faint echoes, which look black on the display screen. On the other hand, waves will bounce off a solid tumor, creating a pattern of echoes that the computer will interpret as a lighter-colored image.

What does liposarcoma look like on ultrasound?

At ultrasonography (US), a well-differentiated liposarcoma appears as a heterogeneous, multi-lobulated, typically well-defined mass. In our experience, sonographic identification of fat as hyperechogenicity is often difficult and variable in well-differentiated liposarcoma, similar to lipoma (,34–,37).
