Abstract

Abstract Background: To compare the effect of obtaining the anteroposterior scout view (APSV) with that of posteroanterior scout view (PASV) on mammary gland dose in pediatric patients. Methods: We used a pediatric anthropomorphic phantom with a 64 detector-row computed tomography (CT) scanner using the APSV or PASV protocol of the chest. A real-time skin dosimeter was placed on the scanner gantry and pasted onto the phantom surfaces of the right and left mammary glands. We compared the real-time skin dosimeter values in the right and left mammary glands between the APSV and PASV protocols at different tube voltages. Results: Compared with APSV, it is possible to reduce the exposure dose by approximately 80% using PASV at different tube voltages (p < 0.05). Conclusion: Obtaining the PASV was helpful in reducing the mammary gland dose by approximately 80% in pediatric patients than that of APSV without deteriorating the image quality of the main scan.
