Extracolonic findings at CT colonography in an oncological hospital setting and why they matter.
Clin Imaging
June 2022
Department of Radiology, Memorial Sloan Kettering Cancer Center, 1275 York Ave, New York, NY 10065, USA. Electronic address:
Purpose: To evaluate the frequency and clinical outcome of unknown extracolonic findings in patients with cancer who underwent CT colonography (CTC).
Methods: Consecutive patients who underwent CTC from February 2000-April 2016 for any indication were retrospectively included. One radiologist blinded to clinical data determined C-RADS classification for all extracolonic findings on CTC reports as follows: E1: normal examination or anatomic variant, E2: clinically unimportant, E3: likely unimportant, incompletely characterized, and E4: potentially important.
Pheochromocytoma is a catecholamine-producing neuroendocrine tumor arising from chromaffin cells of the adrenal medulla. The detection of these tumors is extremely important because they are associated with high cardiovascular morbidity and mortality. Progress in molecular genetics has revealed that up to 35% of pheochromocytomas are inhereted.

Background: Colorectal cancer (CRC) is the third most prevalent cancer in the world and is the second cause of cancer death. Positron emission tomography/computed tomography (PET/CT) using 18F-FDG is used for its staging and follow up.
Aim: To assess the occurrence of synchronous colonic and extracolonic tumors detected with contrast-enhanced F18-FDG PET/CT (PET/CTc) in patients with a recently diagnosed CRC.
Quantitative and qualitative assessment of a coding system for reporting CT colonography.
Clin Radiol
July 2019
University Hospitals of North Midlands, Newcastle Road, Stoke-on-Trent, ST4 6QG, UK. Electronic address:
Aim: To validate a coding system implemented to summarise computed tomography colonography (CTC) findings for the detection of suspected colorectal cancer (CRC) by assessing interobserver variability and also to evaluate any weaknesses through qualitative analysis.
Materials And Methods: All CTC investigations over a 6-month period (01/07/2016 to 31/12/2016) were analysed retrospectively. Each study was read initially by an advanced practitioner radiographer with a final report issued by a consultant gastrointestinal radiologist.
Comparison of extracolonic findings and clinical outcomes in a screening and diagnostic CT colonography population.

February 2019
Department of Radiology, Albert Einstein College of Medicine, Montefiore Medical Center, Bronx, NY, USA.
Purpose: To compare the distribution of extracolonic findings and clinical outcomes between screening and diagnostic CT colonography (CTC) populations.
Methods: 388 consecutive patients (369 men, 19 women; mean ± SD age 67.8 ± 10 years) who underwent first-time CTC (4/2011-4/2017) at a Veteran's Affairs Medical Center were divided into screening (asymptomatic) or diagnostic (symptomatic) cohorts based on CTC indication.
