PURPOSE
BowelPreparationrepresentsa crucialstepfor a successful CT Colonography.
Our study aimed to evaluate a same day iodine bowel preparation for CTcolonography usingIopamidol in asymptomatic and symptomatic patients undergoing CTColonography.
Methods and Materials
Material andmethoths
Fifty consecutive patients,
between 41 and 87y.o.,underwent two days of low fiber diet and assumed 2 tablets of Bisacodyl a night before examination,followed by 2 tablets of Bisacodyl the day of examination with 400ml of water mixed with 64.5g of Macrogol Simeticoneand 70ml of tagging agent (Iopamidol,Gastromiro,Bracco,Italy).
Time to firstevacuation,numberof evacuation episodes occured and mean waiting time after preparation were recorded for all patients.
AVisual Analogue Scale (VAS) was administered to patients in order to evaluate their tolerability toexamination.
Two reviewers independently performed...
Results
RESULTS
Mean number of evacuation episodes was 3 and first evacuationoccuredin 85% of patients just 1 hour after ingestion of preparation.
Mean waiting time after preparation was 1 hour and 45 minutes.
VAS evaluation showed a very hightolerabilty of the exam.
Mean tagging density was 572.
quality was graded 5(excellent)in 90% of all segment.
Mean per-polyp sensitivity for lesions >or=10 mm was 92%.
Mean number of CAD FP's was 10 for prone and 12 for supine series
Conclusion
CONCLUSION
Same-day preparation withIopamidolresults in a very high patient acceptability and has a comparable,
excellent image quality and good diagnostic performance of our standard tagging protocol.
Tolerability of the exam was
very high in 90%of patients
