| description |
The aim of the study is to measure the prevalence and types of abnormalities on CT Colonogra-
phy, and to assess the association between standard colonoscopy and CT Colonography. Another
aim of the study is to determine the level of preference between standard colonoscopy and CT
Colonography. Materials and Method A total of 24 patients were included in the study. All pa-
tients underwent a standard bowel preparation (phospho-soda/Fleet@). Patients underwent CTC
within 4 hours after standard colonoscopy. Su�cient amount of air was insu�ated through rectal
tube for colonic distension prior to scanning. CTC was performed using a 4detector row helical
CT scanner (Somatom Volume Zoom). Image acquisition was done in prone and supine positions.
Scanning parameters were as per CTC protocal. The images were transferred to a remote syngo
Colon Work
ow Assisstant workstation for 2D and 3D data rendering. The endoluminal navi-
gations were performed from rectum to caecum, in both retrograde and antegrade directions in
order to visualize both sides of haustral folds. CTC �ndings were correlated with conventional
colonoscopy �ndings, which were used as standard reference. For assessment of patients preference
between CTC and standard colonoscopy, standard questionnaires were given to patients after both
CTC and standard colonoscopy procedures. Results: A total of 24 patients were included in this
study. Most of the patients were male (66.7%), and majority were Malays (70.8%). Age ranges
from 20-70 years, but most of the patients were more than 40 years of age. Per rectal bleeding
were the most common indication for colonoscopy (29.2%). Abnormal CTC results were detected
in 62.5%. Abnormal results were due to tumour in 29.2%, polyp in 25% and diverticulum in 8.3%.
Correlating with standard colonoscopy results, there is no signi�cant association between the two
studies (P value = 0.092). For level of preference between CTC and standard colonoscopy and �nal
selection between these two procedures, most of the patients were satis�ed with CTC procedure,
which was 62.5%. Conclusion: Even though there were variations in the detection rates of CTC in

patients due to its advantages over standard colonoscopy. |
