Summary: The study evaluated the effectiveness of the Clear VD11 PURE platform system in reducing radiation dose during peripheral arterial endovascular procedures. The results showed a significant decrease in radiation dose after the implementation of the new system, but the reduction in fluoroscopy time was not statistically significant.

Summary: This study aimed to estimate operator organ doses from fluoroscopically guided infrarenal endovascular aneurysm repair (EVAR) procedures using radiation dose structured reports. Monte Carlo methods were used to calculate conversion factors between kerma area product (PKA) and primary operator organ doses. A computer program was developed to estimate operator doses for 81 EVAR procedures. The results showed that with optimal use of shielding, operator doses can be reduced to levels well below statutory dose limits.

Summary: The study aimed to investigate operator's eye lens doses in typical CT-guided interventions, the correlation between dose length product (DLP) and operator's dose, as well as different methods for estimating eye lens dose in clinical settings. Results showed that eye lens doses were generally low in CT-guided interventions, and can be estimated based on DLP or measured dose at the operator's collar level.

Summary: This study evaluated the feasibility of using PR-based PCCT with microbubble contrast agent for vascular imaging. Results showed that microbubbles provided weaker contrast enhancement compared to iodine, but still sufficient for imaging rat aortas. The imaging modality can currently be used as a complement or alternative to absorption-based microCT for imaging vessels in biological samples.

Summary: This study investigates the impact of prolonged exposure to low-dose radiation on cognitive performance. The focus is on the fallout from the Chernobyl accident, which resulted in increased ground radiation levels in Europe. By utilizing unexpected rainfall patterns and the trajectory of the radioactive plume, the researchers are able to identify a causal effect on local fallout and its impact on cognitive test scores. Analysis of geo-coded survey data from Germany reveals a significant decline in cognitive performance 25 years later for individuals exposed to higher radiation levels.

Summary: Deep learning can improve contrast in low-dose cardiovascular MRA. Evaluation of image quality and diagnostic confidence showed comparability between enhanced LD-MRA and HD-MRA. Vessel diameter measurements also demonstrated comparability.

Summary: This study aimed to implement a communication tool with standardised commands to reduce radiation exposure in an orthopaedic department in Ireland. The study evaluated radiation exposure using dose-area product (DAP) and compared pre- and post-intervention groups. The results showed that implementing the communication tool effectively reduced radiation exposure.

Summary: This study evaluated radiation doses to physicians and medical staff in CT-guided interventions, finding that the doses to physicians were higher than those to nurses, with significant correlations between physician doses and CT-fluoroscopy mAs. The study highlights the importance of reducing and optimizing radiation dose to medical personnel in CTIs to minimize the risk of radiation-induced injuries.

Summary: The aim of this study was to assess the value of advanced imaging guidance on radiation exposure and iodinated contrast volume during endovascular treatment of lower extremity arterial disease (LEAD). The results showed that fusion imaging guidance does not affect radiation exposure and contrast volume.

Summary: This study aimed to assess the radiation exposure of neurointerventionalists during endovascular stroke treatment (EST) and compare the exposure on the left arm with the left temple. The results showed that neurointerventionalists experienced radiation exposure during EST, but there was no significant difference in exposure between the left arm and left temple.

Summary: This study aimed to evaluate the radiation dose associated with contrast-enhanced mammography (CEM) in a large population. The results showed a 6.2% difference in radiation dose between two centers, mainly due to the characteristics of the study populations and manufacturing differences. The radiation dose of CEM was about 30% higher than that of standard digital mammography. However, considering the diagnostic gain granted by CEM, radiation dose concerns should not hinder its clinical implementations.

Summary: DLCTA with 70-80 kVp and 200 mg I/kg can reliably detect the presence of endoleak after TEVAR/EVAR, reducing radiation and iodine dose compared to standard CTA.

Summary: The study aimed to compare the precision of maintaining target CNR in angiography between CNR-driven exposure control (CEC) and conventional detector dose-driven exposure control (DEC), as well as estimate the difference in incident air kerma between the two when reaching the same CNR. Results showed that CEC was more effective in maintaining a predefined CNR level compared to DEC, using equal or lower air kerma to provide a given CNR level.

Summary: This study aimed to examine the effects of different postoperative antithrombotic regimens on 3-year clinical outcomes after infrapopliteal bypass for chronic limb-threatening ischemia (CLTI). The results showed that compared to single antiplatelet therapy (SAPT), dual antiplatelet therapy (DAPT) and anticoagulation therapy were not associated with improved outcomes among Medicare beneficiaries who had undergone infrapopliteal bypass for CLTI. These findings suggest that the routine use of DAPT or anticoagulation therapy might not provide clinical benefit in this high-risk, elderly population.

Summary: The study findings indicate that compared to aspirin/clopidogrel, aspirin/ticagrelor may potentially reduce the risk of stroke/death in specific cases involving carotid artery stenting and carotid artery revascularization procedures when protamine is used, while also increasing the risk of bleeding.
