Use of Iterative Reconstruction Method in Ultralow-dose CT for Follow-up of Patients With Intraabdominal Abscess: Comparison With Standard Dose CT

South Korea20 participantsStarted 2018-06-29

Plain-language summary

Increasing radiation exposure by medical examinations is getting more concerns. For optimal medical imaging, reducing radiation exposure with preservation image quality is important. One of the solutions is use of iterative recontruction of CT examination. In this study, the investigators aimed to investigate the clinical feasibility of ultralow dose abdominopelvic CT with iterative reconstruction in patients with intraabdominal abscess. Patients with intrabdominal abscess usually undergo multiple CT examinations to evaluate treatment response. Therefore, ultralow dose CT can reduce unnecessary radiation exposure in these patients.
