Basheerudeen SAS, Kanagaraj K, Jose MT, et al. Entrance surface dose and induced DNA damage in blood lymphocytes of patients exposed to low-dose and low-dose-rate X-irradiation during diagnostic and therapeutic interventional radiology procedures. Mutat Res. 2017 Jun;818:1-6.

The ionizing radiation received by patients and health workers due to radiological imaging may increase the risks of radiation effects, such as cancer and cataracts. We have investigated the dose received by specific areas around the head and related this to DNA damage in the blood lymphocytes of subjects exposed to interventional imaging.

Barakat MT, Thosani NC, Huang RJ, et al. Effects of a Brief Educational Program on Optimization of Fluoroscopy to Minimize Radiation Exposure During Endoscopic Retrograde Cholangiopancreatography. Clin Gastroenterol Hepatol. 2018 Apr;16(4):550-557.

We aimed to evaluate whether a 20-minute educational intervention for endoscopists would improve use of fluoroscopy and decrease ERCP-associated exposure to radiation for patients. At baseline, total radiation dose and dose area product were significantly higher for LVEs, but there was no significant difference between HVEs and LVEs following education. Education was associated with significant reductions in median fluoroscopy time (48% reduction for HVEs vs 30% reduction for LVEs), total radiation dose (28% reduction for HVEs vs 52% for LVEs) and dose area product (35% reduction for HVEs vs 48% reduction for LVEs). All endoscopists significantly increased their use of low magnification and collimation following education.
