A study on radiation doses and irradiated areas in XXXX .

@entity1 @entity1779 @entity4858
@entity1 radiation doses during interventional radiology procedures may reach the thresholds for radiation-induced @entity4858 . This study investigates the irradiated areas and doses received by @entity1 undergoing @entity1779 , which is regarded as a high dose interventional radiology procedure. For each procedure the fluoroscopic and digital dose-area product (DAP), the fluoroscopic time, the total number of acquired images and entrance-skin dose (ESD) calculated by the angiographic unit were recorded. The ESD was measured by means of thermoluminescent dosimeters. In this study, the skin, eye and thyroid gland doses and the irradiated area for 30 @entity1 were recorded. The average ESD was found to be 0.77 Gy for the posteroanterior plane and 0.78 Gy for the lateral plane. The average DAP was 48 Gy cm(2) for the posteroanterior plane and 58 Gy cm(2) for the lateral plane. The @entity1 's average right eye dose was 60 mGy and the dose to the thyroid gland was 24 mGy. Seven @entity1 received a dose above 1 Gy, one @entity1 exceeded the threshold for transient erythema and one exceeded the threshold for temporary epilation. A good correlation between the DAP and the ESD for both planes has been found. The doctor's eye dose has also been measured for 17 procedures and the average dose per procedure was 0.13 mGy.
