[Examination of Exposure Dose by Procedure in Cerebral Angiography].

Objective: In cerebral angiography, the patient's exposure dose varies greatly depending on the target site, purpose, and difficulty of the procedure. Therefore, it is necessary to manage the dose based on not only the disease but also the procedure.

Methods: In this study, diagnostic cerebral angiography (diagnosis group) was classified into 13 procedures and neuro-interventional radiology (treatment group) was classified into 10 procedures, and the total dose, fluoroscopy dose, radiographic dose, fluoroscopy time, and number of radiographic frames were compared.
