Posteroanterior Scout View of Pediatric Patients Using Computed Tomography During Different Tube Voltages: Validation Using Pediatric Anthropomorphic Phantoms

This study aims to compare the effect of obtaining the anteroposterior scout view (APSV) with that of the posteroanterior scout view (PASV) on mammary gland dose in pediatric patients during different tube voltages. 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. Compared with APSV, it is possible to reduce the exposure dose by approximately 80% using PASV at different tube voltages ( p
