ROFO-FORTSCHRITTE AUF DEM GEBIET DER RONTGENSTRAHLEN UND DER BILDGEBENDEN VERFAHREN
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.
