“…Although there have been several reports analyzing a patient's skin dose in neurointerventional procedures, [1][2][3][4][5][11][12][13][14][15][16][17][18] there are few reports that could demonstrate the regional distribution of skin dose. 5,6,19,20 In this study, we demonstrated that the ESD on the area that encompasses the right temporal and occipital region was considerably higher than that on the frontal region.…”

“…Different methods for patient dosimetry in IR have been proposed and tested [22,23,24,25,26,27,28,29]. Basically, all the methods try to obtain the skin dose distribution with different approaches: arrays of TLD dosimeters; slow radiographic films (with the problem of saturation at 1.0-1.5 Gy); radiochromic films (without saturation at several Gy but still expensive and difficult to calibrate and to process); and on-line software, which was offered by Siemens but now is off the market [30].…”

After the alert of the FDA in 1994, about induced skin injuries to patients during fluoroscopically guided procedures, several national and international organizations addressed the topic to improve the safety in interventional radiology. The number and complexity of interventional procedures are increasing during the past years, but the number and rate of skin injuries is not known because no comprehensive monitoring or reporting mechanism exists. In interventional procedures, patient dosimetry is difficult, as X-ray entrance skin areas and different beam projections, field sizes, electronic magnification, radiation qualities, etc., are unpredictable. In addition, service engineers can modify parameters affecting dose and image quality tailoring the systems to the particular requirements of the users. This article reviews the reported skin injuries in the scientific literature. Misuse, X-ray system faults or non-optimized operational protocol gives rise sometimes to the injuries. The available procedures to evaluate patient doses and practical advice to minimize risks are also discussed.

Radiation doses to adult male patients from abdominal aortogram and aorta femoral runoff examinations in a medical center were determined with the help of a dose-area product meter. The abdominal aortogram and aorta femoral runoff examination consisted of scout radiographs, fluoroscopy (to position a catheter near the area of interest), and serial films (to record the flow of contrast media). Measurements were converted to effective doses with the help of published results from Monte Carlo simulation calculations. Data from 19 male adult patients weighing 53 to 86 kg were analyzed. The resulting total effective dose had a value of 14.0 +/- 4A mSv (mean and standard deviation). The percent contribution by fluoroscopy was 18.5 +/- 9.9%. The fluoroscopy effective dose had a stronger correlation with the dose-area product (correlation coefficient of 0.97) than with duration of exposure (correlation coefficient of 0.84). Most of the radiation exposure in the observed abdominal aortogram and aorta femoral runoff examination was attributed to radiography.
