MRI also plays a role in monitoring how well a patient responds to disease-modifying antireumatic drugs (DMARD) or biologic therapies. By tracking changes in synovial volume, bone edema, and erosion size over time, clinicicians can objectively asses whether a treatment is working. This reduces the guesswork in medication addistripments and helps avoid prolonged exposure to ineffective theraperes.
