Computed tomography (CT) colonography is the established successor to the barium enema for the detection of colonic neoplasia due to superior performance and patient experience. Consequently, CT colonography is widely disseminated across Western populations and increasingly provided by both subspecialist and general radiologists alike. As a result, CT colonography is now part of the core training curriculum for radiology in the UK. However, study data shows wide performance gaps between centres and between individuals of differing experience, which is perhaps unsurprising given the complexity of the CT colonography technique and interpretation. This article summarizes the background, evolution and recommendations of the CT colonography standards document (Appendix) developed by the International CT Colonography Standards Collaboration, which included highly experienced radiologists, radiographers, gastroenterologists, and screening experts. These standards are intended to guide and support radiology teams across the world by promoting methods for improving the quality of CT colonography technique and the patient experience.

The variability in interpretation of colonic codes in CT colonography reporting: a single-centre experience.
Clin Radiol
October 2024
Department of Radiology, Nottingham University Hospitals NHS Trust, Nottingham, UK. Electronic address:
Aim: Although standardised summary codes to classify colonic findings (C-codes) on computed tomography colonography (CTC) have been used for several years, there is no clear guidance on how these codes should be interpreted. The aims of this study were to (1) establish CTC C-code demographics and reporting practice at our hospital and (2) determine the agreement between CTC reporters when using C-codes.
Materials And Methods: Waiving ethical approval, this online questionnaire study invited all radiologists, reporting radiographers and radiology trainees who reported CTC at our hospital between 22/02/2023 and 05/03/2023.
Article Synopsis
- This study examines whether a new method of CT colonography (CTC) using Auto-kVp selection, higher preset ASIR-V, and noise index can effectively reduce radiation dose while accurately detecting colorectal tumors.
- Ninety patients underwent two types of CTC: standard dose (SDCTC) and ultra-low dose (ULDCTC), with results showing significantly lower radiation exposure for ULDCTC while maintaining or improving image quality.
- Both CTC methods demonstrated high rates of tumor detection and consistent tumor location results when compared with surgical findings, suggesting that the new method is a viable option for safer colorectal cancer screening.
AI-based abdominal CT measurements of orthotopic and ectopic fat predict mortality and cardiometabolic disease risk in adults.

Objectives: To evaluate the utility of CT-based abdominal fat measures for predicting the risk of death and cardiometabolic disease in an asymptomatic adult screening population.
Methods: Fully automated AI tools quantifying abdominal adipose tissue (L3 level visceral [VAT] and subcutaneous [SAT] fat area, visceral-to-subcutaneous fat ratio [VSR], VAT attenuation), muscle attenuation (L3 level), and liver attenuation were applied to non-contrast CT scans in asymptomatic adults undergoing CT colonography (CTC). Longitudinal follow-up documented subsequent deaths, cardiovascular events, and diabetes.

Background: Since 2003, a decline in the age-standardized incidence rates of colorectal cancer (CRC) has been observed in Germany. Nonetheless, one in eight cancer cases still affects the colon or rectum. The prognosis has improved, with the relative 5‑year survival rate for CRC being approximately 65%.

Background: The Paris classification categorises colorectal polyp morphology. Interobserver agreement for Paris classification has been assessed at optical colonoscopy (OC) but not CT colonography (CTC). We aimed to determine the following: (1) interobserver agreement for the Paris classification using CTC between radiologists; (2) if radiologist experience influenced classification, gross polyp morphology, or polyp size; and (3) the extent to which radiologist classifications agreed with (a) colonoscopy and (b) a combined reference standard.
