Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Abscess

Patients group with abdominal abscess

ultralow dose abdominopelvic CT

Intervention Type OTHER

In the patient cohort with abdominal abscess, ultralow dose abdominopelvic CT will be performed as a follow-up protocol. Ultralow dose CT has approximately 80\~90% reduced radiation dose compared to standard dose CT.
