Given the preference for limb-sparing surgeries, many bone tumor resections require the implantation of hardware which creates local artifact that can obscure the adjacent tissues. Few studies comparing the use of MRI for local recurrence of bone tumors compared with other modalities have been published in recent years likely given its widespread adoption clinically. MRI is often requested before surgery and radiation when local recurrence is established. Given many local recurrences are soft tissue masses, the use of IV contrast remains beneficial to help characterize masses as malignant or benign and can also increase reader confidence [67,68]. MRI Area of Interest Without IV Contrast MRI of the primary tumor resection site has further asserted its usefulness for surveillance of local recurrence with improvements in metal artifact reduction.

MRI is often requested before surgery and radiation when local recurrence is established. Given many local recurrences are soft tissue masses, the use of IV contrast remains beneficial to help characterize masses as malignant or benign and can also increase reader confidence. However, the inherent contrast resolution of MRI, even in the absence of IV contrast, makes this a useful modality to assess for local recurrence of malignant or aggressive primary bone tumors [67,68]. 10 Malignant or Aggressive Primary Musculoskeletal Tumor Radiography Area of Interest Not only is radiography useful to evaluate for bone tumor recurrence, but it is also an invaluable adjunct to MRI interpretation.
