Investigation of dose indicators for breast cancer CT localization procedures in radiation therapy in Croatia
Computed tomography (CT) has become an integral component of modern radiotherapy. CT data obtained is used for individual treatment planning and accurate localization. However, there is a growing awareness of the dose delivered to the part of the body outside the target volume. Ionizing radiation carries a stochastic risk of malignancy ; therefore, doses should be kept as low as reasonably achievable in order to provide an adequate information needed for radiotherapy planning. The aim of this study was to investigate the variation in CT localization scanning protocols for breast cancer patients between radiotherapy centers in Croatia. Data collection sheets were distributed to all institutions performing this type of procedure. All of them responded and a retrospective data collection was performed. Computed Tomography Dose Index volumetric, Dose-Length Product and scan length were recorded and statistically analyzed. The national diagnostic reference level for breast cancer CT protocol in radiation therapy is proposed and compared to other seldom published data. This study provides a platform for dose comparison and optimisation of planning CT protocols in breast cancer. Results will be presented.
