Abstract
Purpose: The purpose of this prospective and randomized study was to compar e two CT guidance techniques (CT-fluoroscopy/conventional CT) on percutaneo us biopsies, drainages and gastrostomies. Material and Methods: 78 CT-guide d interventions (29 biopsies, 38 drainages, 8 gastrostomies) were recorded and the Mann-Whitney U-test was applied. In 3 cases both guidance technique s were used. Procedure times, yields and radiation doses were analyzed. Res ults: All 38 drainages and all 8 gastrostomies were successfully applied. 1 3 biopsies with conventional CT guidance (n=15) and 13 biopsies with CT-flu oroscopy (n=14) showed a representative histopathologic result. The procedu re times were not significantly different (drainages: p=0.658, biopsies: p= 0.431, gastrostomies: p > 0.06). The radiation doses (CTID1) of the biopsie s and drainages showed significantly higher values (drainages p < 0.001, bi opsies p < 0.001) with CT-fluoroscopy than with conventional CT. There were no significant differences in gastrostomy procedures (p > 0.06). Conclusio n: Procedure times and yields were not improved by using CT-fluoroscopy. Ra diation doses showed significantly higher values with CT-fluoroscopy than w ith conventional CT guidance. CT-fluoroscopy was advantageous in non-compli ant patients over conventional CT guidance.
