5 risk factors help predict brain hemorrhage on CT
August 17, 2018 -- U.K. researchers have identified five factors -- including contrast leakage on CT scans -- that may indicate a higher risk of continued bleeding in the brain of stroke patients. Checking for these factors may help improve survival, according to an article published online on August 14 in Lancet Neurology.  Discuss
Are patients adequately informed about CT lung screening?
August 13, 2018 -- Physicians may not be adequately explaining the harms and benefits of CT lung cancer screening to eligible smokers, according to an article published online August 13 in JAMA Internal Medicine.  Discuss
3 reasons why trauma injuries are missed on whole-body CT
August 9, 2018 -- There are three major characteristics that predict which patients presenting with multiple traumatic injuries will have their injury overlooked on a whole-body CT exam, according to an August 7 article in Radiology. Identifying these risk factors early could help improve injury detection.  Discuss
Variation in CT, MRI protocols can be reduced
August 8, 2018 -- Researchers from Boston successfully cut by almost one-third the number of CT and MRI protocols being used in their health network. They believe the streamlining will lead to more consistent patient care with less waste, according to an article published online August 3 in the Journal of the American College of Radiology.  Discuss
CT lung screening may benefit racial minorities most
August 2, 2018 -- Despite decreasing overall lung cancer mortality rates in the U.S., the racial disparity in deaths from the disease continues to widen. Tailoring CT lung cancer screening programs to inner-city, high-risk minority smokers may help bridge the gap, say Illinois researchers in a letter published online August 2 in JAMA Oncology.  Discuss
Global lung cancer death rates for women to increase
August 1, 2018 -- Global lung cancer mortality rates for women will increase by 43% from 2015 to 2030, at which point more women are projected to die from lung disease than breast cancer, according to a study published online August 1 in Cancer Research.  Discuss
Ultralow-dose CT with CAD helps detect lung nodules
August 1, 2018 -- An ultralow-dose CT protocol involving computer-aided detection (CAD) matched the accuracy of standard CT for identifying lung nodules at just 10% of the radiation dose of a standard scan, according to an article published online July 25 in the Journal of Thoracic Imaging.  Discuss
Can AI enhance the utility of breast conebeam CT?
July 30, 2018 -- An artificial intelligence (AI) algorithm for breast conebeam CT (CBCT) studies can accurately differentiate between benign and malignant breast lesions, potentially improving the real-world performance of radiologists reading CBCT images, according to a Web-exclusive paper in the August issue of the American Journal of Roentgenology.  Discuss
Is CT or US better for diagnosing gallbladder infection?
July 30, 2018 -- CT was found to be considerably more accurate than ultrasound at identifying acute cholecystitis in a new study, published in the August issue of the American Journal of Roentgenology. But is that enough evidence for CT to oust ultrasound as the imaging modality of choice? Probably not, say researchers from New Mexico.  Discuss
Could a blood test rule out most CT for brain injury?
July 25, 2018 -- A blood test that detects biomarkers for brain injury could help rule out patients suspected of having traumatic intracranial injuries, thus avoiding the need for CT scans, according to a large multicenter observational trial published online July 24 by Lancet Neurology.  Discuss
