WebModern CT scanners provide two dose parameters that both became available by the scanner manufacturers around 2001: the Volume CTDI (CTDIvol) measured in mGy, and the dose-length product (DLP) measured in mGy-cm. CTDIvol is a measure of the average dose within the scan volume to a standardized phantom. The total amount of radiation … WebThe study shows that there is room for optimization. New Icelandic NDRLs were proposed for the total DLP of CT examinations based on ten different indications, including: Brain ischemia (1060 mGycm), Interstitial lung disease (310 mGycm) and Appendicitis (690 mGycm). The proposed NDRLs were the first clinical indication based NDRLs in Iceland. WebThe objective of our study was to compare dose–length product (DLP)–based estimates of effective dose with organ dose–based calculations using tissue-weighting factors from publication 103 of the International Commission on Radiological Protection (ICRP) or dual-energy CT protocols.
