Article Synopsis
- * Researchers included 400 adult oncology patients from 8 PET-CT centers and calculated various dose metrics such as CT dose index (CTDIvol) and dose-length product (DLP) to assess the effectiveness of dose reduction practices over the past few years.
- * The results showed that the proposed 2022 local DRLs for half-body and whole-body scans improved significantly from 2020, with values lower than those from Switzerland and France but slightly higher than the UK, indicating ongoing optimization in imaging practices.
Objective: Diagnostic reference levels (DRLs) for CT part of positron emission tomography-CT (PET-CT) examinations are limited. The study was aiming to execute the second phase of the national DRL in support of optimisation and dose reduction in State of KW.
Methods: In this multicentre collaborative PET-CT study, oncology patient data were exclusively collected due to the National MOH Ethical Committee recommendation and limitation of the other studies.
Many discrepancy in selection of proper filter and its parameters for individual cases exists. The authors investigate the impact of the most common filters on patient NM images with coronary artery disease (CAD), and compare the results with the computerized tomography (CT)-Angio and angiography for accuracy.The investigation initiated by performing various single photon emission computerized tomography (SPECT)/CT scan of the national electrical manufacturers association chest phantoms having hot and cold inserts.
