“…Radiation reduction can be done in many ways, such as administering radiation education to interventional cardiologists as well as catheterization lab staff [6]. One ideal method is renewal of the X-ray equipment in catheterization labs by purchasing the latest machines, up-to-date software, and realtime dose monitoring [7,8]. However, financial constraints limit accessibility for many catheterization labs.…”

Backgrounds: Reducing radiation exposure is the basic principle for performing percutaneous coronary intervention (PCI). Many studies have confirmed the effect of radiation protection for medical staff, but studies about the effectiveness of protection for patients and real measurement of radiation dose in patients’ specific organs are lacking. Aim: To measure the radiation doses absorbed by patients’ radiosensitive organs during PCI and the effectiveness of radiation protection. Methods: A total of 120 patients were included and allocated into three groups as the ratio of 1:1:2. A total of 30 patients received PCI at 15 frames rate per second (fps), 30 patients at 7.5 fps, and 60 patients wore radiation protective hat and glasses during PCI at 7.5 fps. The radiation doses were measured at right eyebrow (lens), neck (thyroid), back (skin), and inguinal area (genital organs) by using thermoluminescent dosimeters (TLDs). Results: Dose-area product (DAP) reduced by 58.8% (from 534,454 ± 344,660 to 220,352 ± 164,101 mGy·cm2, p < 0.001) after reducing the frame rate, without affecting successful rate of PCI. Radiation doses measured on skin, lens, genital organs, and thyroid decreased by 73.3%, 40.0%, 40.0%, and 35.3%, respectively (from 192.58 ± 349.45 to 51.10 ± 59.21; 5.29 ± 4.27 to 3.16 ± 2.73; 0.25 ± 0.15 to 0.15 ± 0.15; and 17.42 ± 12.11 to 11.27 ± 8.52 μSv, p < 0.05). By providing radiation protective equipment, radiation doses at lens and thyroid decreased further by 71.8% and 65.9% (from 3.16 ± 2.73 to 0.89 ± 0.79; 11.27 ± 8.52 to 3.84 ± 3.49 μSv, p < 0.05). Conclusions: By lowering the frame rate and providing protective equipment, radiation exposure in radiosensitive organs can be effectively reduced in patients.

“…Assessing the effectiveness of best practices for radiation safety requires both in lab patient dose tracking as well as post‐procedure follow‐up of high dose patient exposure. Ichimoto et al, in this issue of CCI , address the potential for procedural radiation dose reduction through a technique providing visual real time patient dosimetry for operator radiation dose awareness .…”

Real time radiation dose monitoring in the cath lab may provide immediate feedback for potential dose reduction during PCI. Radiation dose monitoring to predict potential tissue injury utilizes equipment measured air Kerma at the interventional reference point (IRP) with then calculated specific tissue peak skin dose. The role of the cath lab Quality Committee is not only to assess individual high dose radiation cases but also to create processes and assess new technologies to assure radiation dose is best utilized in all cases.
