摘要

本研究旨在为摩洛哥一家医院的乳腺癌计算机断层扫描成像放射治疗（CT-RT）建立当地诊断参考水平（LDRL）。研究人员在五个月内收集了 106 名年龄在 33 岁至 78 岁之间的成年乳腺癌患者的数据。数据是通过摩洛哥一家地区肿瘤中心的日立 Supria 16 片 CT 模拟器获得的。CT-RT 图像用于三维适形放射治疗规划。剂量长度乘积（DLP）和容积计算机断层扫描剂量指数（CTDIvol）是通过确定第75百分位数作为CT-RT乳腺癌的诊断参考水平进行评估的。根据 DLP 和 CTDIvol 确定了 CT-RT 乳腺癌的 LDRL，分别为 330.4 mGy.cm 和 6.8mGy。该 DRL 与其他欧洲研究进行了比较。该研究的 DRL 值低于英国、克罗地亚和斯洛文尼亚的 DRL 值。这项研究的结果可作为摩洛哥制定地方和国家 DRL 以及优化 CT-RT 乳腺癌手术的参考。

Etablissement de niveaux de référence diagnostiques locaux pour les protocoles de tomodensitométrie en radiothérapie du cancer du sein dans un seul centre marocain

The objective of this study was to establish local diagnostic reference levels (LDRLs) for breast cancer computed tomography imaging in radiotherapy (CT-RT) at a single hospital in Morocco. Data were collected from 106 adult breast cancer patients aged between 33 and 78 years during five months. Data were obtained using a Hitachi Supria 16-slice CT simulator at a regional oncology center in Morocco. CT-RT images are intended for 3D conformal radiotherapy treatment planning. Dose length product (DLP) and volumetric computed tomography dose index (CTDIvol) were evaluated by determining the 75th percentile as diagnostic reference levels for CT-RT breast cancer. LDRLs for CT-RT breast cancer have been determined in terms of DLP and CTDIvol, and they were 330.4 mGy.cm and 6.8mGy, respectively. The DRLs were compared with other Europeans study. DRLs for this study were lower than those for the United Kingdom (UK), Croatia and Slovenia. The results of this study can be a reference for the establishment of local and national DRLs in Morocco and the optimization of CT-RT breast cancer procedures.

期刊介绍： Radioprotection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes (theoretical and practical aspects): dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments.
