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.

Patient Radiation Dose Management in the Follow-Up of Potential Skin Injuries in Neuroradiology

“…We reported cumulative skin doses, obtained from the cumulative air kerma at the patient entrance reference point and displayed by most of the modern x-ray systems, 13 while other authors have measured or estimated peak skin doses. [7][8][9][10][11][12][13] Table 2 (adapted by the authors) compares the results reported by several authors. Our cumulative skin doses and DAPs are in the range of other published values.…”

“…Our cumulative skin doses and DAPs are in the range of other published values. [7][8][9][10][11][12][13] In 2009, 19 patients (5.9% of the total number of procedures included in the data base during that year) were included in a follow-up program for potential skin injuries. That year, 20 procedures (2 in the same patient) resulted in cumulative skin doses (frontal and lateral planes together) higher than 5 Gy.…”

“…6 Several evaluations of cumulative skin dose have been made in interventional neuroradiology procedures. [7][8][9][10][11][12][13] Radiation-induced skin injuries can sometimes occur after a clinically complex procedure, but may also, on other occasions, result from the use of inappropriate equipment or poor operational techniques. The ICRP states that acute radiation doses may cause erythema at 2 Gy and delayed skin necrosis at 12 Gy.…”

Local skin and eye lens equivalent doses in interventional neuroradiology

“…After their embolisation treatment of small aneurysms, the maximum skin dose was located on the back of the head behind the right ear. Moritake et al [31] extended the study to 32 patients and found maximum skin dose on the back of the head at the level of the ears. Hence, we conclude that the position of maximum skin dose in their study agrees with the positions of our TLD on our 71 patients.…”

A Comparison of Radiation Exposure between Diagnostic CTA and DSA Examinations of Cerebral and Cervicocerebral Vessels

“…5 The absorbed doses of organs predict the deterministic risks such as a temporary epilation, hair loss, or opacity of the lens. [6][7][8][9] Previous investigations have indicated a large variation between radiation exposures for cervical and cerebral angiography, depending on the imaged area and the imaging technique used. 2,3,[10][11][12][13][14] A comparison of the radiation exposure between CTA and DSA methods has not been previously performed by using the same dose-measurement setup, to our knowledge.…”
