CT Area of Interest Without and With IV Contrast CT remains useful for surveillance of local recurrence when MRI is unable to be obtained. CT imaging can also be of benefit if metal artifact on MRI cannot be resolved, although it should be noted CT is also susceptible to artifact from metal hardware. When evaluating the soft tissues, postcontrast imaging is recommended to increase the conspicuity of enhancing tumors and, if so, areas of necrosis that can help with biopsy planning and to serve as a baseline for future therapy response assessment. However, CT without and with IV contrast is usually not recommended over CT with IV contrast alone.

CT imaging can also be of benefit if metal artifact on MRI cannot be resolved, although it should be noted CT is also susceptible to artifact from metal hardware. When evaluating the soft tissues, postcontrast imaging is recommended to increase the 11 Malignant or Aggressive Primary Musculoskeletal Tumor conspicuity of enhancing tumors and, if so, areas of necrosis that can help with biopsy planning and to serve as a baseline for future therapy response assessment. FDG-PET/CT Whole Body FDG-PET/CT has the added benefit of not only thin-slice CT imaging but also the ability to detect metabolically active disease. FDG-PET/CT is highly accurate in detecting recurrent soft tissue and bone sarcomas, and may be useful as a problem-solving tool when other imaging of the area of interest is equivocal. A retrospective single- institution study of 43 patients with bone or soft tissue sarcomas found better sensitivity and specificity of FDG- PET/CT follow-up versus contrast-enhanced CT imaging (94% and 92% versus 78% and 67%, respectively) [79].
