“…We have been continuously applying efforts to lower the radiation dose in our hospital's neuroangiography suite. 1,2 According to a previous multi-center study, our level of radiation dose during cerebral angiography and embolization procedures is one of the lowest among the hospitals in Korea. 3 However, we believe that there is still scope for further dose reduction, which is attributed to fluoroscopy.…”

“…Despite the development of non-invasive modalities such as computed tomography and magnetic resonance imaging, diagnostic cerebral angiography remains essential for the diagnosis of many neurovascular diseases. We have been continuously applying efforts to lower the radiation dose in our hospital’s neuroangiography suite [ 1 , 2 ]. According to a previous multi-center study, our level of radiation dose during cerebral angiography and embolization procedures is one of the lowest among the hospitals in Korea [ 3 ].…”

Purpose: We applied a low-dose fluoroscopic protocol in routine diagnostic cerebral angiography and evaluated the feasibility of the protocol.Materials and Methods: We retrospectively reviewed a total of 60 patients who underwent diagnostic cerebral angiography for various neurovascular diseases from September to November 2019. Routine protocols were used for patients in the first phase and low-dose protocols in the second phase. We compared radiation dose, fluoroscopy time, and complications between groups.Results: Age, diseases, and operators were not significantly different between the two groups. The mean fluoroscopy dose significantly decreased by 52% in the low-dose group (3.09 vs. 6.38 Gy·cm<sup>2</sup> ); however, the total dose was not significantly different between the two groups (34.07 vs. 33.70 Gy·cm<sup>2</sup> ). The total fluoroscopic time was slightly longer in the low-dose group, but the difference was not statistically significant (12.2. vs. 12.5 minutes). In all patients, angiography was successfully performed without complications.Conclusion: The low-dose fluoroscopy protocol is feasible to apply for diagnostic cerebral angiography in that this protocol could significantly reduce the fluoroscopic dose.

“…3 ). In a phantom study, Song et al [ 9 ] demonstrated that an increase in the cranial angulation or caudal angulation resulted in a greater radiation dose during routine cerebral angiography. Specifically, a cranial angulation of 20 degrees increased the AK by 5.4%, compared to the true PA projection.…”
