CT Guided Biopsy And Drainage

CT-guided percutaneous biopsies are performed in patients with a known primary tumor, to rule out metastatic malignancy, to establish the final diagnosis, or to differentiate between tumor necrosis and potential vital tumor tissue in residual lesions after therapy. CT-guided aspiration, punch, and drill biopsy may be performed in essentially every organ system and location, and overall complication rates are low.
