CT Area of Interest Without IV Contrast Although CT is well-suited for demonstration of osseous erosions, there is no relevant literature supporting the use of CT area of interest without IV contrast for the evaluation of erosive osteoarthritis in the extremities following initial radiographs. FDG-PET/CT Whole Body There is no relevant literature supporting the use of FDG-PET/CT whole body for the evaluation of erosive osteoarthritis in the extremities following initial radiographs. Chronic Extremity Joint Pain Image-Guided Aspiration Area of Interest There is no relevant literature supporting the use of image-guided aspiration for the evaluation of erosive osteoarthritis in the extremities following initial radiographs. MRI Area of Interest Without and With IV Contrast MRI can show the features of erosive osteoarthritis, although the findings may be nonspecific, potentially mimicking other types of joint inflammation. The addition of IV contrast may aid in the differentiation of synovitis from joint effusion [23]. MRI Area of Interest Without IV Contrast MRI can show the features of erosive osteoarthritis, although the findings may be nonspecific, potentially mimicking other types of joint inflammation. US Area of Interest US may demonstrate synovial hypertrophy, marginal osteophytes, and central erosions [76] but is not routinely used in clinical practice for the evaluation of erosive osteoarthritis. Both US and contrast-enhanced MRI have been shown to perform equally in the demonstration of synovitis of the fingers associated with erosive osteoarthritis [76]. However, synovitis on US is nonspecific and may be seen with erosive osteoarthritis and inflammatory arthritis.
