“…Recent data for P KA are available in the international literature for interventional fluoroscopy procedures. Among others, Peruzzo Cornetto et al tabulated data for 23 procedures in an Italian hospital, Compagnone et al published data from a different Italian hospital for nine interventional procedures, Dauer et al published P KA data for 43 interventional fluoroscopy procedures at a single U.S. institution, Bundy et al did the same for 12 procedures at a different U.S. medical center, Erskine et al published P KA data for 32 interventional fluoroscopy procedures in Australia, Étard et al’s report contains data from France for 15 procedures, Pitton et al published data for 17 interventional vascular procedures at a German hospital, Schmitz et al reported data on biliary interventions at 23 different facilities, and Ruiz‐Cruces et al reported data for seven interventional procedures performed at eight hospitals in Spain. Many other published studies were also consulted to estimate one or more of P KA , E , and DC E …”

“…An additional issue is the variability in naming and grouping interventional procedures in the literature. Some reports provide very granular categorization of procedures, while others group similar procedures and still others combine the two approaches . With highly granular categories, fewer data points are included in each category.…”

When a category simply reflects a general description of various procedures in the same anatomic region, and relatively large amounts of data were available, the unweighted average of E for the procedures was assigned for this category; when only limited data were available, judgment based on clinical experience was used.…”

Purpose To provide current data on average air kerma‐area product (PKA) and effective dose (E) for noncardiac interventional fluoroscopy procedures and suggested values of dose coefficients (DCE) for conversion of PKA to estimates of effective dose. Methods A PubMed literature search covering the time period from 2006 to August 2019 was performed to obtain recent data on PKA, E and DCE for interventional fluoroscopy procedures. Results There is very wide variation in the reported values of PKA, E, and DCE in the literature. A number of factors are involved in this variability and the resultant uncertainty in average values of these dose quantities. Conclusions The values of PKA, average E and suggested DCE presented here can be of use for comparison of the radiation detriment from different procedures and may be useful for categorizing detriment within an order of magnitude or so. They do not represent actual or expected radiation dose or detriment from any specific procedure or for a specific patient and should be not be used as such.

Modified design of x‐ray protective clothing to enhance radiation protection for interventional radiologists

2023

Background: In interventional radiology procedures, the operator typically stands on the right side of the patient's right thigh to manipulate devices through the femoral sheath. Because the standard x-ray protective clothing is designed as sleeveless and scatter radiations from the patient are mainly incident from the left-anterior direction to the operator, the arm hole of the clothing may be a significant unprotected area, contributing to an increase in the operator's organ doses and effective dose.Purpose: This study aimed to compare the organ doses and effective dose received by the interventional radiologist when wearing the standard x-ray protective clothing and when wearing the modified clothing with an additional shoulder guard. Methods: The experimental setup aimed to simulate actual clinical practice in interventional radiology. The patient phantom was located at the beam center to generate scatter radiation. An adult female anthropomorphic phantom loaded with 126 nanoDots (Landauer Inc., Glenwood, IL) was used to measure organ and effective doses to the operator. The standard wrap-around type x-ray protective clothing offered 0.25-mm lead-equivalent protection, and the frontal overlap area offered 0.50-mm lead-equivalent protection. The shoulder guard was custom-made with a material providing x-ray protection equivalent to lead of 0.50 mm thickness. The organ and effective doses were compared between the operator wearing the standard protective clothing and the one wearing the modified clothing with a shoulder guard. Results: After adding the shoulder guard, doses to the lungs, bone marrow, and esophagus decreased by 81.9%, 58.6%, and 58.7%, respectively, and the effective dose to the operator decreased by 47.7%. Conclusions: Widespread use of modified x-ray protective clothing with shoulder guards can significantly decrease the overall occupational radiation risk in interventional radiology.
