The main goal of this study was to assess the viability of the bismuth breast shield in chest computed tomography (CT ) examinations. Dose measurements on a phantom (Cardinal Health 76 415) with an ionisation chamber were performed with and without bismuth breast protection in different configurations using the routine chest CT protocol. Image quality control was performed using a phantom (Gammex 464). In all measurements with bismuth protection (no sponges), we observed a dose decrease of 22.6%. Dose decreased by 19.9% with protection (one sponge), 17.6% with protection (two sponges) and 28.2% with the protection coupled to the gantry. It is therefore appropriate to implement the protection configuration coupled to the gantry as a protective measure for patients undergoing chest CT scans.
