AI Article Synopsis
- - The study aimed to assess the optimization of common computed tomography (CT) procedures by measuring the volume computed tomography dose index (CTDIvol) and dose-length product (DLP) during various examinations.
- - Results indicated that variations in CTDIvol and DLP were primarily due to differences in the techniques employed, with specific values established for different CT procedures across multiple hospitals.
- - The findings, including key CTDIvol values (40.9, 9.0, 9.4, and 16.2 mGy) and corresponding DLP values (900, 360, 487, and 721 mGy.cm), provide a foundation for enhancing the optimization of CT procedures in the country.
Article Abstract
The aim of this study was to evaluate optimisation status during common computed tomography (CT) procedures by determining values of volume computed tomography dose index (CTDIvol) and dose-length product (DLP) per examination. Patient and exposure data were collected from the CT console during various CT procedures. The results show that variations in CTDIvol and DLP values were mainly because of differences in the techniques used. The 75th percentile values were set as the third quartile of the median CTDIvol or DLP values for all hospitals. These values of 40.9, 9.0, 9.4 and 16.2 mGy for CTDIvol were determined for head, high-resolution chest, abdomen-pelvis and lumbar spine, respectively. The corresponding DLP values for the same sequence of CT procedures were 900, 360, 487 and 721 mGy.cm, respectively. The updated results provide a basis for optimising the procedures of CT in this country.
