Ultrasound: Musculoskeletal ultrasound is being used more often for detecting soft tissue abnormalities such as tendon tears, joint effusions, and cellulitis. Ultrasound would show fluid in tendon sheaths and joint vs subcutaneous soft tissue swelling. Radiographs show better abnormalities affecting bones such as fracture, tumor, and bone infection.

MRI: If you want to know it is free fluids or swelling of the tissue, MRI is the best test for that.
