Comparison of DLP and CTDI in somatom Definition Flash and GE revolution computed tomography scanners at AIIMS, India

The increasing radiation exposure from computed tomography (CT) scans raises concerns about patient safety, necessitating the comparison of radiation dose parameters across different CT scanners. This study compares the Dose Length Product (DLP) and Computed Tomography Dose Index (CTDI) values between the Somatom Definition Flash and GE Revolution CT scanners at AIIMS, New Delhi. Our findings reveal that the Somatom scanner consistently operates within international Diagnostic Reference Levels (DRLs), while the GE scanner shows significantly higher radiation doses, particularly for chest and abdomen scans. This research advances the understanding of CT dose optimization and highlights the need for scanner-specific protocols to ensure radiation safety.
