“…In the present study, the average maximal ESD during procedures for single-stenosis was 1.4±0.9 Gy, which agrees with the findings of Hwang et al who reported that the mean skin dose of 25 single-stent cases was 1,529± 601 mGy. 20 Of the present 97 PCI procedures, the maximal ESDs exceeded 1 Gy and 3 Gy in 75 and 16 procedures, respectively. The exposure dose is affected by the type of angiographic unit, the mode of operation for fluoroscopy and image acquisition, and the protocols used for the PCI procedures.…”

“…Real-time measurements of skin dose are possible only at one or a few selected points on the skin (15). A radiolucent probe using either a metal-oxide semiconducting field-effect transistor, or MOSFET (Med-Tec, Orange City, Iowa), or a scintillation dosemeter (McMahon Medical, San Diego, Calif) (15)(16)(17) is placed at the presumed point of peak skin dose.…”

Skin injury is a deterministic effect of radiation. Once a threshold dose has been exceeded, the severity of the radiation effect at any point on the skin increases with increasing dose. Peak skin dose is defined as the highest dose delivered to any portion of the patient's skin. Reducing peak skin dose can reduce the likelihood and type of skin injury. Unfortunately, peak skin dose is difficult to measure in real time, and most currently available fluoroscopic systems do not provide the operator with sufficient information to minimize skin dose. Measures that reduce total radiation dose will reduce peak skin dose, as well as dose to the operator and assistants. These measures include minimizing fluoroscopy time, the number of images obtained, and dose by controlling technical factors. Specific techniques-dose spreading and collimation-reduce both peak skin dose and the size of skin area subjected to peak skin dose. For optimum effect, real-time knowledge of skin-dose distribution is invaluable. A trained operator using well-maintained state-of-the art equipment can minimize peak skin dose in all fluoroscopically guided procedures.

“…MONITORING OF skin entrance radiation exposures in lengthy interventional radiological procedures has been investigated, proposed, and conducted by various means (Hwang et al 1998;McParland 1998;Wagner and Pollock 1999;O'Dea et al 1999;van de Putte et al 2000;Vano et al 2001Vano et al , 2003Fletcher et al 2002;Guibelalde et al 2003;Miller et al 2003;Efstathopoulos et al 2004;Bor et al 2004). Radiochromic film has been used in dosimetry since as early as 1990 (Farahani et al 1990) for external beam radiation therapy and 1991 for brachytherapy (Muench et al 1991).…”

Monitoring of skin entrance radiation exposure in lengthy interventional procedures has been recommended because of the potential for skin injury. Fluoroscopy duration and dose-area product (DAP) are readily available real-time measurements. It would be of interest to study the correlation of these parameters and skin entrance radiation. Twenty neurological interventional procedures performed through the aortic arch were monitored. Two pieces of GafChromic XR Type R film were placed between the patient and the examination table. An observer recorded the fluoroscopy duration and DAP for each phase of the procedure. Each film was scanned post-procedure in RBG mode, and then the image was analyzed for peak skin entrance radiation dose (in air kerma). All DAP values were corrected according to a calibration with an ion chamber. With the DAP values for the respective phases of a procedure, the effective dose in a Reference Man was calculated. For these twenty cases, the means and standard deviations were 17.2+/-6.4 min for x ray on-time, 256+/-65 Gy cm (-2) for DAP, 94+/-34 cGy for peak skin entrance dose in air kerma, and 19.2+/-5.0 mSv for effective dose, respectively. The peak skin entrance dose was correlated to fluoroscopy duration, DAP, and effective dose with the r(2)-values of 0.48, 0.46, and 0.09, respectively. The correlation with DAP or fluoroscopy duration was not sufficiently strong to infer skin entrance dose from either of these parameters. Therefore, skin entrance dose should be determined directly.
