Abstract
Radiation doses for interventional examinations are generally high and therefore necessitate dose monitoring for patients and staff. Relating the staff dose to a patient dose index, such as dose-area product (DAP), could be quite useful for dose comparisons. In this study, DAP and skin doses of 57 patients, who underwent neurointerventional examinations, were measured simultaneously with staff doses. Although skin doses were comparable with the literature data, higher DAP values of 215 and 188.6 Gy cm 2 were measured for the therapeutical cerebral and carotid examinations, respectively, owing to the use of biplane system and complexity of the procedure. Mean staff doses for eye, finger and thyroid were measured as 80.6, 77.6 and 28.8 μGy per procedure. The mean effective dose per procedure for the radiologists was 32 μSv. In order to allow better comparisons to be made, DAP normalised doses were also presented.

In this study, measurements of dose-area product (DAP) and entrance dose were carried out simultaneously in a sample of 162 adult patients who underwent different interventional examinations. Effective doses for each measurement technique were estimated using the conversion factors that have been determined for specific X-ray views in a mathematical phantom. Exposure conditions used in clinical practice never match these theoretical models exactly, and deviations from the assumed standard condit...

We investigated radiationdoses to 149 adult patients who underwent interventional neuroradiologic procedures, consisting of 132 patients who had diagnosticimaging examinations and 17 patients who had therapeutic procedures. The interventional procedures were carried out on a biplane system capable of performing fluoroscopy and digital subtraction angiography(DSA). The x-ray imaging system was interfaced to a patient dosimetry system, which computed surface (skin) doses based on the selected radi...

In interventional cardiology (IC) staff can be exposed to high dose levels due to the long fluoroscopy procedures performed Staff dosimetry can yield information on the optimisation level of radiation protection, which is influenced by the equipment performance, auxiliary protection devices, training in radiation protection and procedure complexity.

The Food and Drug Administration (FDA) has recommended the monitoring of radiationskindose to patients during procedures having the potential for radiation damage.Radiologists need information about typical radiationdoses during interventional procedures. The skindoses to patients during 522 interventional neuroradiological procedures have been monitored using an automated dosimetry system. Estimated entrance skindoses (ESD) were binned into 0.5 Gy increments and compared to FDA recommended thre...

The purpose of this study was to obtain representative quantitative information on exposure conditions and entrance doses of occupationally exposed persons (workers) in diagnostic and interventional arteriography. In a study in three hospitals all parameters of the X ray systems that are related to the exposure of workers were quantified with an automatic data acquisition system. Using LiF thermoluminescence dosemeters, entrance doses to workers were measured at the forehead, neck, thorax, abdom...

Abstract Vascular interventional procedures carried out under fluoroscopic guidance often involve high radiation doses. Above certain thresholds, radiation can cause significant damage to the skin including hair loss and severe necrosis. Such damage has been reported by several investigators. Many attempts have been made to quantitate the radiation doses to the skin involved with these procedures, but dosimetry methods are often flawed. To improve the situation better monitoring of radiation dos...

Patient skin doses resulting from interventional radiological procedures have the potential to exceed threshold doses for deterministic effects such as erythema and epilation. If the irradiation geometry is known, the entrance skin dose can be estimated from the measured dose-area product. For each of 10 non-coronary interventional procedures, a nominal geometry was identified. From a previous survey of patient dose-area products, the entrance skin doses were estimated under the assumption that ...

Radiation exposure during angiography is relatively high compared with other types of radiological procedures. In order to estimate the integral radiation dose absorbed by the patient, the applied dose-area product (DAP) is the most appropriate measurement The purpose of this study was a systematic recording of measured fluoroscopic DAP, spot DAP, and total DAP as well as detailed examination data acquired at our Department of Diagnostic Radiology to obtain a profile of the radiation exposure in...

In recent years surveys have been performed in the Netherlands to determine patient doses for various types of examination in diagnostic radiology. These surveys comprised examinations of chest, breast, colon, computed tomography and non-cardiovascular radiology procedures. In general, in these studies measurements were performed at 10 to 20 X ray units in different hospitals. The majority of the studies aimed at determination of effective dose as this quantity is generally assumed to he most di...

Within the past 10 years special fluoroscopy guided examinations have increasingly been performed. New techniques such as interventional radiology are requiring long periods of fluoroscopy causin high doses to patients Different factors affect patient exposure in fluoroscopy compared to radiography. Hoth examination practice and technical parameters influence dose. The consequences are demands for new reference dose values. One single reference value cannot give enough information, therefore at ...

Abstract Introduction Intracranial aneurysm coil embolisation is a fluoroscopically guided procedure associated with high radiation dose. The increase in the number of coil embolisation procedures raises concern for the amount of radiation and the associated radiation risks to the patients. This research study was conducted to determine the average radiation dose to patients’ thyroid glands and local skin during intracranial aneurysm coil embolisation and to establish preliminary local diagnosti...

Objectives There is potential for high radiation exposure during neurointerventional procedures. Increasing regulatory requirements mandate dose monitoring of patients and staff, and justification of high levels of radiation exposure. This paper demonstrates the potential to use radiation dose-tracking software to establish local diagnostic reference levels.

Abstract The ionizing radiation received by patients and health workers due to radiological imaging may increase the risks of radiation effects, such as cancer and cataracts. We have investigated the dose received by specific areas around the head and related this to DNA damage in the blood lymphocytes of subjects exposed to interventional imaging. The entrance surface doses (ESD) to the forehead, neck, and shoulder were measured with a thermoluminescence dosimeter (CaSO 4 disc or polycrystallin...

BACKGROUND AND PURPOSE: Neurointerventional surgery may expose patients and physician operators to substantial amounts of ionizing radiation. Although strategies for reducing patient exposure have been explored in the medical literature, there has been relatively little published in regards to decreasing operator exposure. The purpose of this study was to evaluate the efficacy of shielding systems in reducing physician exposure in a modern neurointerventional practice. MATERIALS AND METHODS: Inf...

BackgroundIn interventional neuroradiology, few operators routinely use radiation protection glasses. Moreover, in most centers, radiation dose data only accounts for whole body dose without specific information on lens dose. In 2012, the International Commission on Radiological Protection advised that the threshold limit value for the lens should be 20 mSv/year instead of the previous 150 mSv/year limit. The purpose of this study was to compare the radiation dose in the operator’s lens during r...
