Background & Aims: We prospectively compared the performance of low-dose multidetector
computed tomographic colonography (CTC) without cathartic preparation with that of …

PURPOSE: To determine, by using multi–detector row helical computed tomography (CT),
the added value of obtaining unenhanced and delayed phase scans in addition to biphasic …

PURPOSE: To compare the performance of lower-dose multi–detector row helical computed
tomographic (CT) colonography with that of conventional colonoscopy in the detection of …

PURPOSE: To evaluate whether the use of two arterial phase image acquisition series,
when combined with portal venous phase imaging at multi–detector row helical computed …

PURPOSE: To prospectively evaluate the diagnostic accuracy of low-radiation-dose
computed tomographic (CT) colonography for detection of colorectal polyps by using two …

Our objective was to evaluate the feasibility of ultra-low-dose scanning for multislice CT
colonography in the detection of colorectal lesions. Twenty-seven patients (14 men, 13 …

Our objective was to optimize a scanning protocol for CT colonography using a multidetector
scanner with an adaptive-array matrix in a phantom study. A colonic phantom with 27 …

Purpose The purpose of our study was to evaluate the efficacy of multislice spiral CT
colonography: 1) in the diagnosis and staging of colorectal carcinoma; 2) in the evaluation of …

Our purpose was to assess the effect of reader experience, fatigue, and scan findings on
interpretation time for CT colonography. Nine radiologists (experienced in CT …

The extent measurement error on CT colonography influences polyp categorisation
according to established management guidelines is studied using twenty-eight observers of …
