Abstract No. 516 Risk of postcontrast acute kidney injury in patients with gastrointestinal (GI) bleeding undergoing computed tomography angiography (CTA) followed by visceral angiography within 24 hours
The use of iodine-based contrast agents may lead to nephropathy, and patients with underlying chronic kidney disease (CKD) are at increased risk for this complication. In a recent study of patients with stroke who underwent CTA followed by cerebral angiography, 9.5% of patients developed postcontrast acute kidney injury.1 The purpose of this study was to assess the risk of postcontrast acute kidney injury in patients with GI bleeding undergoing CTA followed by visceral angiography within 24 hours.

Sex Difference of Radiation Response in Occupational and Accidental Exposure
Conclusion and Outlook This review summarizes the data from major human studies on the health risks of radiation exposure and shows that sex can potentially influence the prolonged response to radiation exposure (Figure 1 and Tables 1, 2). These data suggest that long-term radiosensitivity in females is higher than that in males who receive a comparable dose of radiation. Our analysis of the literature agrees with the conclusions of the recent report on the Biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences (NAS), United States (National Research Council, 2006). The B...

Iodine Extravasation Quantification on Dual-Energy CT of the Brain Performed after Mechanical Thrombectomy for Acute Ischemic Stroke Can Predict Hemorrhagic Complications INTERVENTIONAL
CONCLUSIONS: The presence of parenchymal hyperdensity with a maximum iodine concentration of >1.35 mg/mL may identify patients developing intracerebral hemorrhage with 100% sensitivity and 67.6% specificity.
