Abstract

Objective: To evaluate the image quality and radiation dose reduction of chest computed tomography (CT) using combined automated tube potential selection (ATPS) and iterative reconstruction (IR). Materials and Methods: Image quality and radiation dose were compared between conventional contrast-enhanced chest CT using 120 kVp and filtered back projection (Protocol A) and CT using ATPS and IR (Protocol B) in 43 patients. Results: The effective radiation dose was 3.6±0.4 mSv for Protocol A and 2.2±0.6 mSv for Protocol B (mean dose reduction, 39.7%). Protocol B showed diagnostic image quality in all patients. Conclusion: ATPS and IR allows for radiation dose reduction while maintaining diagnostic image quality.
