Radiation Dose Assessment In Pediatric Chest Ct Protocols With Emphasis On Ctdivol And Dlp

Pediatric chest computed tomography (CT) is an essential diagnostic tool, children's increased radiosensitivity and extended life expectancy present serious difficulties. With an emphasis on the Computed Tomography Dose Index volume (CTDIvol) and Dose Length Product (DLP), this paper evaluates the state of the art on radiation dose assessment in various pediatric chest CT protocols. By comparing radiation doses from normal, low-dose, high-resolution, and ultra-low-dose protocols, we highlight dose optimization techniques such iterative reconstruction, size-specific dose estimating (SSDE), and adherence to the ALARA (As Low As Reasonably Achievable) doctrine. In order to standardize and reduce radiation exposure while maintaining diagnostic quality, it is emphasized how crucial it is to create size-based diagnostic reference levels (DRLs). The purpose of this paper is to provide guidance to radiographers and physicians on safer imaging procedures/protocols for children
