However, CT, be it without IV contrast, with IV contrast, or without and with IV contrast, may provide complementary information, particularly in respect to assessing matrix mineralization, cortical destruction, or in suspected cases of osteoid osteoma. If contrast is given, CT without and with IV contrast is preferred because it allows differentiation of areas of contrast enhancement from areas of osseous matrix production. However, radiographic evaluation is generally recommended as the next best imaging modality. FDG-PET/CT Whole Body Radiographic evaluation is generally recommended as the next best imaging modality to evaluate bone lesions incidentally found on MRI and CT. FDG-PET/CT may play a limited role in the evaluation of bone lesions incidentally found on MRI and CT. MRI Area of Interest If the initial MRI is not of sufficient quality (eg, limited coverage, limited sequences, etc) or was performed using a nonmusculoskeletal protocol (eg, an incidentally discovered bone lesion on a prostate MRI), then a repeat MRI examination may be warranted. However, this should typically follow radiographic imaging, which can be used to better plan the repeat MRI. Supplementation of an MRI initially performed without IV contrast with contrast- enhanced sequences may provide additional information about lesion vascularity and relationship to regional vascular structures. MRI evaluation of the area of interest may provide complementary information facilitating further assessment of the lesion and can be helpful in preoperative planning. Although there is no relevant literature regarding the use of MRI in the evaluation of bone lesions incidentally found on CT, MRI may provide complementary information, particularly with regard to evaluating soft-tissue components. However, radiographic evaluation is generally the next best imaging modality.
