Objectives: Although contrast-enhanced abdominal computed tomography is frequently used to detect possible postoperative complications in living liver donors, radiation exposure remains a major concern. For this reason, we used low-dose postoperative computed tomography scans. We compared radiation doses of low-dose postoperative computed tomography with those of standard-dose preoperative computed tomography in living liver donors. Materials and Methods: This retrospective study included 80 living liver donors (median age of 28.0 years; 40 male participants) who underwent standard-dose preoperative and low-dose postoperative abdominal computed tomography scans between 2023 and 2024. Results: The median dose length product and effective dose with low-dose postoperative computed tomography were significantly lower than with standard-dose preoperative computed tomography (72.6 vs 371.0 mGy·cm and 1.1 vs 5.6 mSv, respectively; all P < .001). Conclusions: Low-dose postoperative computed tomography scans can significantly reduce radiation dose in living liver donors.
