Dose measurement on both patients and operators during neurointerventional procedures using photoluminescence glass dosimeters.

ABSTRACT:

Background and purpose

Although radiation skin injuries associated with interventional radiology have been known as a critical issue, there are few reports mentioning direct measurement of the entrance skin dose (ESD). Thus, the purpose of this study was to clarify the regional distributions of ESDs in neurointervention.

Materials and methods

Using photoluminescence glass dosimeters (PLDs), we measured the ESDs in 32 patients with a median age of 61.5 years. Angiographic parameters, including exposure time, dose-area product (DAP), and the number of digital subtraction angiography (DSA) studies and frames, were recorded. The ESDs of operators were analyzed by the same method.

Results

The maximum ESD of 28 therapeutic procedures was 1.8 +/- 1.3 Gy. Although the average
