RESUMO
BACKGROUND: We wished to evaluate the utility of computed tomography fluoroscopy (CTF) for guiding percutaneous abdominopelvic biopsies or fluid aspirations that are considered difficult with conventional computed tomographic (CT) guidance. METHODS: CTF-guided percutaneous biopsy (n = 11) or fluid aspiration (n = 2) was attempted in 13 patients with lesions that were otherwise difficult or potentially unsafe by conventional CT guidance because they were deep to colon, small intestine, or major blood vessels. RESULTS: Using CTF assistance to guide external compression or needle positioning, appropriate needle placement was performed in 11 patients. Biopsy or aspiration was diagnostic in 10 patients. Needle advancement was not attempted in two patients. CONCLUSION: CTF appears to be a valuable tool to dynamically assist percutaneous needle placement into lesions that may be considered difficult with standard CT assistance.
