“…Data from large studies on screening cohorts have suggested that CTC and conventional colonoscopy have similar sensitivity for polyps ≥6-mm in diameter [8,9]. Moreover, patients generally prefer CTC instead of barium enema examination or colonoscopy [10][11][12][13]. However, concerns were raised about recommending CTC as routine screening tool because of potential harm [14,15].…”

a b s t r a c tAim: To retrospectively study the frequency and magnitude of complications associated with computed tomography (CT) colonography in clinical practice. Methods: A questionnaire on complications of CT colonography was sent to Italian public radiology departments identified as practicing CT colonography with a reasonable level of training. The frequency of complications and possible risk factors were retrospectively determined. Responses were collated and row frequencies determined. A multivariate analysis of the factors causing adverse events was also performed. Results: 40,121 examinations were performed in13 centers during the study period. No deaths were reported. Bowel perforations occurred in 0.02% (7 exams). All perforations were asymptomatic and occurred in patients undergoing manual insufflation. Five perforations (71%) occurred in procedures performed following a recent colonoscopy. There was no significant difference between perforations associated with rectal balloon (0.017%) and those that were not (0.02%). Complications related to vasovagal reaction (either with or without spasmolytic) occurred in 0.16% (63 exams). All vasovagal reactions resolved in less than 3 h, without any sequelae. Conclusions: Perforation rate at CT colonography in Italy is comparable with elsewhere in the world, occurring regardless of the experience of radiology centers. Although the risk is very small, it may not be negligible when compared with the risk of diagnostic colonoscopy.

“…It was demonstrated that noninvasive methods such as CT virtual colonoscopy [15], MR cholangiopancreatography [16], and MR angiography of the carotid arteries [17] are more widely accepted by patients than the traditional invasive approaches [18][19][20][21][22][23].…”

“…In fact, the success of a method is undeniably associated with the intrinsic acceptance of the method by the patients, who are increasingly pursuing noninvasive and outpatient diagnostic examinations [14]. On the one hand, recent studies have shown that noninvasive tools such as CT virtual colonoscopy [15], magnetic resonance (MR) cholangiopancreatography [16], and MR angiography of the carotid arteries [17] are widely accepted by patients more than the traditional invasive approach, on the other hand it is known that conventional coronary angiography (CCA) may cause intense concern and anxiety in the patients and affect their quality of life especially in the hours before the examination, with the need for pharmacological and/or psychological treatment [18][19][20][21][22][23].…”

Purpose This study was done to evaluate the psychological state and anxiety of patients undergoing computed tomography coronary angiography (CTCA), and assess their acceptance and satisfaction compared to invasive conventional coronary angiography (CCA). Materials and methods A total of 442 consecutive patients (282 male; mean age 57.7 ± 9.5 years) who underwent CTCA for suspected or known coronary artery disease were evaluated with the Endler Multimodality Anxiety Scales (EMAS) before and after the scan, and a questionnaire administered after the scan. Among the 442 patients, 181 had a history of CCA. Two radiologists assessed the image quality of CTCA.

“…However, there have been reports about a possible correlation between nephrogenic fibrosing dermopathy (NFD) and the intravenous administration of gadolinium compounds (20). As far as patient acceptance is concerned, several trials revealed a higher acceptance rate for virtual colonography compared to optical endoscopy (21)(22)(23). The need to undergo bowel cleansing yet is rated as the most unpleasant part of the virtual colonography exam (21-25) and patient discomfort scores can be significantly improved with tagging preparations previously shown for CT colonoscopy (CTC) (26).…”

Purpose:To evaluate if different patient characteristics influence performance of fecal tagging (a new MR colonography (MRC) technique to label stool to avoid bowel cleansing) and, consecutively, MR image quality. Materials and Methods:A total of 333 patients (mean age ϭ 61 years) underwent MRC with fecal tagging. Four segments of the large bowel (ascending, transverse, descending, and sigmoid colon) were assessed as for the presence of nontagged stool particles, which can impede an assessment of the colonic wall. Ratings were correlated with patients' characteristics including patient age (Ͻ55 vs. Ն55 years), body mass index (BMI) (Ͻ25 vs. Ն25), gender, and acceptance levels for fecal tagging. Statistical analysis was performed using a Mann-Whitney U-test.Results: A total of 1332 colonic segments were evaluated. Among them, 327 segments (25%) did not contain any visible stool particles. Considerably reduced image quality was found in 61 segments (5%). Best image quality was found in the sigmoid colon (mean value ϭ 1.9), while image quality of the ascending colon turned out to be worst (mean value ϭ 2.6). Fecal tagging effectiveness showed a reverse correlation with patient age. However, all other characteristics did not have a statistically significant influence on fecal tagging outcome.Conclusion: MRC in conjunction with barium-based fecal tagging led to diagnostic image quality in 95% of all colonic segments. Since tagging results were significantly decreased in patients Ն55 years, tagging protocols should to be modified in this group, i.e., by increasing the time interval of tagging administration.

Abstract: CT colonography was considered less painful and less difficult overall than colonoscopy and was the preferred examination.
