However, if such lesions are symptomatic, CT imaging without IV contrast may be useful to identify complications or for surgical planning. FDG-PET/CT Whole Body FDG-PET/CT is not routinely used in the evaluation of lesions that are definitely benign on radiographs. There is no relevant literature regarding the use of FDG-PET/CT in the evaluation of definitely benign primary bone tumors. Primary Bone Tumors MRI Area of Interest MRI is not routinely used in the evaluation of lesions that are definitely benign on radiographs. If such lesions are symptomatic, MRI may be useful to identify unusual complications, such as stress fracture, secondary aneurysmal bone cyst formation, or malignant transformation [13]. Bone Scan Whole Body Bone scan is not routinely used in the evaluation of lesions that are definitely benign on radiographs. There is no relevant literature regarding the use of Tc-99m bone scan in the evaluation of definitely benign primary bone tumors. US Area of Interest US is not routinely used in the evaluation of lesions that are definitely benign on radiographs. There is no relevant literature regarding the use of US in the evaluation of definitely benign primary bone tumors. Variant 4: Suspect primary bone tumor. Radiographs or clinical presentation suggest osteoid osteoma. Next imaging study. CT Area of Interest CT is considered the optimal imaging modality in patients with suspected osteoid osteoma. CT is preferred over MRI when osteoid osteoma is strongly suspected because it is extremely sensitive for detection and precise delineation of the nidus [14], which is important both for diagnosis and treatment. In a study including 19 patients with histologically proven osteoid osteoma who underwent CT and MRI before excision of the lesion, Assoun et al [15] found that CT was more accurate than MRI in detection of the osteoid osteoma nidus in 63% of cases.
