Usefulness of non-lead aprons in radiation protection for physicians performing interventional procedures
TL;DR: In this study, the radiation protection effects of commercially available protective lead and non-lead aprons, when exposed to diagnostic X rays, are compared and the performance of these non- Lead aprons was similar for scattered X rays at tube voltages of 60-120 kV.
Journal ArticleDOI
Relationship Between Fluoroscopic Time, Dose–Area Product, Body Weight, and Maximum Radiation Skin Dose in Cardiac Interventional Procedures
Koichi Chida,Haruo Saito,Hiroki Otani,Masahiro Kohzuki,Shoki Takahashi,Shogo Yamada,Kunio Shirato,Masayuki Zuguchi +7 more
TL;DR: The correlation between the maximum radiation skin dose with DAP is more striking than that with fluoroscopic time in both RFCA and percutaneous coronary intervention procedures and it is recommended that physicians record the DAP when it can be monitored and that Physicians record the fluoroscope time when DAP cannot be monitored for estimating the maximum patient skin dose in RFCA procedures.
Journal ArticleDOI
Occupational dose in interventional radiology procedures
Koichi Chida,Yuji Kaga,Yoshihiro Haga,Nozomi Kataoka,Eriko Kumasaka,Taiichiro Meguro,Masayuki Zuguchi +6 more
TL;DR: The occupational dose determined using one badge under the apron was far lower than the dose obtained with two badges in both physicians and nonphysicians, suggesting use of two monitoring badges to evaluate interventional radiology nurses as well as physicians.
Journal ArticleDOI
Radiation dose to the pediatric cardiac catheterization and intervention patient.
Koichi Chida,Tadayuki Ohno,Shuhei Kakizaki,Mika Takegawa,Hiroko Yuuki,Mitsuru Nakada,Shoki Takahashi,Masayuki Zuguchi +7 more
TL;DR: There was a good correlation between the DAP and weight and between D AP and weight-fluoroscopic time product for children who underwent cardiac catheterization or an interventional radiology procedure, and body weight is important for determining radiation dose.
