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.

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Patients group with abdominal abscess
Other: ultralow dose abdominopelvic CT
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.
Score of subjective image quality of CT image
Score of subjective image quality of CT images consists of overall subjective image quality, noise, diagnostic ability, and artifact.
Time frame: 1 month
Effective radiation dose: CTDIvol(volume CT dose index), DLP(dose length product), effective dose(DLPx0.015)
Effective radiation dose between standard dose CT and ultra-low dose CT will be compared
Time frame: 1 month
