Ionizing radiation exposure from medical diagnostic imaging has greatly increased over the last few decades. Approximately 80% of patients who undergo medical imaging are exposed to low-dose ionizing radiation (LDIR). Although there is widespread consensus regarding the harmful effects of high doses of...
Radiation doses were assessed, excluding cases with incomplete data. The study included 32 procedures in the fluoroscopy group and 30 in the CT group.#In the CT-guided group, the median effective dose was 0.21 mSv. The median number of CT scans per procedure was 4.5, and the median ...
It has been well-established that acute radiation exposures increase the risk of leukemia. However, it is still unknown whether these leukemia risk estimates could be extrapolated to occupational populations who receive repeated low-dose radiation exposure. The purpose of this study was to estimate qu...

Prenatal exposure to cadmium is also associated with increasing epigenetic effects on the offspring's multi-organ functions. However, whether and how maternal exposure to low-dose cadmium impacts the risks of developing type 2 diabetes (T2D) in the young and/or adult offspring remains unclear. ...
Improving Cone-Beam CT Angiography for Prostatic Artery Embolization: Is a Low-Dose Protocol Equivalent to the Standard? Purpose To compare the utility of low-dose versus standard cone-beam computed tomography (CT) angiography protocols in identifying nontarget embolization (NTE) during prostatic ...
a positive impact of very low-dose radiation has been reported on distal femur cancellous bone in C57BL/6J adult mice who were exposed to collimated head-only iron-ion 56Fe dose with a collimator interposed between the beam and the animals, resulting in a 0.04 Gy exposure of the hindlim...
dose radiation,7 equivalent to the upper limit dose from a full-body spiral CT scan8 and 2–4 Gy as high-dose radiation that causes substantial DNA damage to cells,9,23 4 Gy is close to the LD50 for human whole-body exposure.24 Using gH2AX as a surrogate marker of DNA damage,23 ...
These results suggest that the radiation-induced early hatching effect is observed for low doses of X-rays. 展开 关键词: Zebrafish Low-dose X-rays Hatching Blastula period Embryos DOI: 10.1016/S0013-9351(03)00042-2 被引量: 46 年份: 2003 ...
Forty-eight individuals, who received protracted low-dose rate γ-irradiation from radioactive environments for 2–10 years, have been evaluated repetitively for cytogenetic damage by the cytochalasin-B micronuclei assay (CBMN) after they relocated from radioactive buildings. These subjects were shown ...
