Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subjects with no abnormalities in renal function (Serum creatinine \< 1.4 mg/dl , GFR \> 45mL/min/1.73 m2) in blood tests performed within one month
* Those who understand the contents of the research subject explanation and voluntarily sign the consent form

Exclusion Criteria

* Body mass index \> 30
* Subjects whose renal function abnormality was confirmed in a blood test (Serum creatinine \> 1.4 mg/dl , GFR \< 45mL/min/1.73 m2) conducted within one month
* Diabetic patients taking metformin
* Those with a history of urinary tract obstruction
* Those with a history of bladder, urinary tract, or kidney surgery that may affect the evaluation of the contrast agent in the renal parenchyma
* Those whose anatomical deformities have been identified in previous images that may interfere with image analysis
* Those who know or have been reported to have a history of contrast agent side effects in previous CT scans
* Those with a history of hypersensitivity or adverse reactions to iobrix (intravascular CT contrast) or iodine based agent
* Those with severe thyroid disease
* Pregnancy
* Those who are judged unsuitable for clinical trials by the researcher for reasons such as having other severe diseases or being judged to have a high risk of adverse reactions to intravascular contrast agents
