Article Synopsis
- The study focuses on measuring radiation doses in interventional neuroradiology (INR) procedures to assess the impact of procedure complexity on patient radiation exposure.
- Data was collected from 332 patients with different conditions (unruptured aneurysms, dural arteriovenous fistulas, and arteriovenous malformations), finding higher skin and lens doses in more complex cases like DAVF and AVM compared to URAN.
- Results highlighted significant correlations between radiation doses and reference air kerma, suggesting the need for better radiation protection measures in complex cases.
The purpose of this study was to investigate the dose distribution and lens doses associated with C-arm cone-beam computed tomography (CBCT), using a head phantom, and to estimate the contribution ratio of C-arm CBCT to each patient's lens dose during interventional neuroradiology ('lens dose ratio') in 109 clinical cases. In the phantom study, the peak skin doses and respective right and left lens doses of C-arm CBCT were as follows: 63.0 ± 1.

Using radio-photoluminescence glass dosimeter, we measured the entrance skin dose (ESD) in 46 cases and analyzed the correlations between maximum ESD and angiographic parameters [total fluoroscopic time (TFT); number of digital subtraction angiography (DSA) frames, air kerma at the interventional reference point (AK), and dose-area product (DAP)] to estimate the maximum ESD in real time. Mean (± standard deviation) maximum ESD, dose of the right lens, and dose of the left lens were 431.2 ± 135.
