This study aimed to determine and compare the patient radiation dose of intracranial aneurysm patients undergoing cerebral angiography using the conventional and high kV techniques in a retrospective study and a phantom study. A total of 122 cases (61 cases with conventional technique and 61 cases with high kV technique) of intracranial aneurysm patients, who underwent cerebral angiographic procedure and met the inclusion criteria, were recruited. The radiation dose and the angiographic exposure parameters were reviewed retrospectively. The radiation dose in the phantom study was conducted using nanoDotTM optically stimulating luminescence (OSLD), which were placed on the scalp of the head phantom, the back of the neck, and the phantom skin at the position of the eyes. The standard cerebral angiographic procedure using the conventional and high kV techniques was performed following the standard protocol. The results showed that the high kV technique significantly reduced patient radiation dose and phantom skin dose. This study confirms that the implementation of a high kV technique in routine cerebral angiography for aneurysm diagnosis provides an effective reduction in radiation dose. Further investigation of radiation dose in other interventional neuroradiology procedures, particularly embolization procedure, should be performed.<\/jats:p>","DOI":"10.3390\/tomography9020050","type":"journal-article","created":{"date-parts":[[2023,3,9]],"date-time":"2023-03-09T03:03:23Z","timestamp":1678331003000},"page":"621-632","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Comparing Radiation Dose of Cerebral Angiography Using Conventional and High kV Techniques: A Retrospective Study on Intracranial Aneurysm Patients and a Phantom Study"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5330-9421","authenticated-orcid":false,"given":"Woranan","family":"Kirisattayakul","sequence":"first","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Khon Kaen University, Khon Kaen 40002, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Panuwat","family":"Pattum","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Khon Kaen University, Khon Kaen 40002, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Waranon","family":"Munkong","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Khon Kaen University, Khon Kaen 40002, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6292-9040","authenticated-orcid":false,"given":"Thawatchai","family":"Prabsattroo","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Khon Kaen University, Khon Kaen 40002, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chonnatcha","family":"Khottapat","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Khon Kaen University, Khon Kaen 40002, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanyalak","family":"Chomkhunthod","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Khon Kaen University, Khon Kaen 40002, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vithit","family":"Pungkun","sequence":"additional","affiliation":[{"name":"Office of Atoms for Peace, Ministry of Higher Education, Science, Research and Innovation, Bangkok 10900, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,8]]},"reference":[{"key":"ref_1","first-page":"124","article-title":"Hemorrhagic Stroke: Aneurysmal Subarachnoid Hemorrhage","volume":"108","author":"Martin","year":"2011","journal-title":"Mo Med."},{"key":"ref_2","first-page":"50","article-title":"Hemorrhagic Stroke: Intracerebral Hemorrhage","volume":"108","author":"Rymer","year":"2011","journal-title":"Mo Med."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"427","DOI":"10.1016\/S1474-4422(09)70080-8","article-title":"ISAT Collaborators Risk of Recurrent Subarachnoid Haemorrhage, Death, or Dependence and Standardised Mortality Ratios after Clipping or Coiling of an Intracranial Aneurysm in the International Subarachnoid Aneurysm Trial (ISAT): Long-Term Follow-Up","volume":"8","author":"Molyneux","year":"2009","journal-title":"Lancet Neurol."},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"853054","DOI":"10.3389\/fneur.2022.853054","article-title":"Prevalence and Risk Factors for Unruptured Intracranial Aneurysms in the Population at High Risk for Aneurysm in the Rural Areas of Tianjin","volume":"13","author":"Liu","year":"2022","journal-title":"Front.
