Fluoroscopic versus Conventional Computed Tomography-Guided Biopsy.

Background/objective: to determine the success rate of computed tomographic (ct) fluoroscopic ct (fct) and conventional ct (cct) for needle navigation in biopsies from mediastinum, bone, abdomen, liver and pelvis. patients and methods: data from 122 consecutive percutaneous interventional biopsies performed with use of fct guidance (mean age of 50.5; range: 1–79 years) and 84 consecutivebiopsies with cct guidance (mean age: 50.7; range, 12–83 years) were gathered from the interventional radiologist and general practitioner.results: the success rate of procedure was increased in the fct group as compared with that of cct group in some organs such as bone, abdomen, liver and pelvis. a statistically significant difference was noted when we compared fct group with cct in liver biopsies (p=0.019). the mean procedure time was lower in fct group. the overall mean (±sd) fct time was 200±90 (range: 20–400) sec; in cct group, it was 420±260 (range: 605–800) second. conclusion: fct facilitates ct-guided biopsy procedures and reduces the procedure time by allowing visualization of the needle tip from skin entrance to the target point.
