Role of iv contrast material in MRI of musculoskeletal tumors
What is the role of intravenous contrast material in MRI of musculoskeletal tumors?
Contrast enhancement may be used to help distinguish tumor margins and to assess tumor vascularity. It may also help distinguish malignant viable tissue from inflammatory changes and necrosis for preoperative biopsy planning. For a follow-up or post-therapy MRI evaluation, contrast enhancement may be helpful to assess tumor response to chemotherapy, to determine the presence of a fluid collection, and to detect tumor recurrence.
