It is time to think inside the (collimation) box; a quality improvement project to reduce over-scanning in CT scanning of the kidneys, ureters and bladder

摘要

Objective: The Royal College of Radiologists (RCR) recommend CT of the kidneys, ureters and bladder (CTKUB) as the first-line investigation for renal colic, stating that excess scan length above the upper pole of the highest kidney should not exceed 10% of the total scan length. The project aim was to determine what proportion of CTKUB scans performed at a district general hospital (DGH) were meeting this standard and explore improvement options as necessary.
