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.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
