What test that monitors joint swelling?

The test that monitors joint swelling is often the ultrasonography (ultrasound) of joints, which allows healthcare providers to visualize and assess the presence of synovial fluid and inflammation in the joints. Additionally, magnetic resonance imaging (MRI) can also be used for a more detailed view of joint structures and swelling. Clinically, physical examination and patient-reported outcomes are also essential in assessing joint swelling and related symptoms.
