OBJECTIVE: The purpose of our study was to describe and review the accuracy of a novel technique for difficult biopsy of arterial tumor encasement using simultaneous IV contrast enhancement and helical CT guidance for coaxial core needle biopsies. CONCLUSION: Diagnostic biopsy specimens can be obtained safely using simultaneous IV contrast-enhanced CT guidance during difficult biopsies of unresectable tumors encasing the celiac, superior mesenteric, or left renal arteries.
