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 contrastenhanced 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. [ABSTRACT FROM AUTHOR]
