Virtual reality adds depth to brain aneurysm diagnosis
June 20, 2018 -- Radiologists detected brain aneurysms just as accurately by examining CT scans with a virtual reality device as they did by reviewing conventional CT angiography and 3D rotational angiography scans, researchers reported in the July issue of Clinical Neurology and Neurosurgery.  Discuss
New 3D CT technique tops x-ray for diagnosing arthritis
June 19, 2018 -- Researchers from the U.K. have developed an algorithm capable of detecting subtle changes in the spacing between arthritic joints on 3D-reconstructed CT scans better than even standard x-ray imaging can, according to an article published online on June 18 in Scientific Reports.  Discuss
Patient outreach may boost uptake for CT lung screening
June 18, 2018 -- Amidst disappointing uptake of CT lung cancer screening, one group of researchers was able to buck the trend within a U.S. Veterans Affairs health network. The key? Bolstering outreach to eligible smokers, according to an article in the June American Journal of Managed Care.  Discuss

June 15, 2018 -- As expected, the Trump administration has formalized its plans to impose tariffs on a wide variety of products manufactured in China. Effective July 6, more than 800 products -- including a range of medical imaging technologies -- will be hit with 25% import tariffs.  Discuss
Are good intentions good enough for reducing CT dose?
June 15, 2018 -- CT radiation dose has been the target of a variety of recommendations, protocols, and guidelines designed to reduce how much dose patients receive. But despite good intentions, radiology may not be doing all it can to reduce CT radiation dose, according to a June 12 opinion article in the American Journal of Roentgenology.  Discuss
Stress echo beats CCTA for evaluating chest pain
June 13, 2018 -- Stress echocardiography is a safe method of evaluating chest pain in patients who present to the emergency department, resulting in lower rates of hospitalization and shorter hospital stays when compared with coronary CT angiography (CCTA), according to a study published online June 13 in JACC: Cardiovascular Imaging.  Discuss
CT links brain calcifications to smoking, diabetes
June 12, 2018 -- Researchers from the Netherlands examined the brain CT scans of patients with memory complaints and identified a strong association between the presence of calcifications in the hippocampus and various risk factors including smoking and diabetes, according to an article published online June 12 in Radiology.  Discuss
Are we using the right metrics for CT lung screening?
June 8, 2018 -- CT lung cancer screening has been shown to reduce mortality when administered to high-risk smokers, but a new study is questioning whether the right metrics are being used to demonstrate this reduction, according to an article published online June 7 in JAMA Oncology.  Discuss
Deep learning accurately detects brain hemorrhage
June 7, 2018 -- A deep-learning algorithm can provide high sensitivity and specificity for detecting brain hemorrhage on noncontrast head CT studies, according to research presented last week at the Society for Imaging Informatics in Medicine annual meeting in National Harbor, MD.  Discuss
More follow-up CT doesn't improve colorectal cancer outcome
June 5, 2018 -- Increasing the frequency of follow-up CT exams for patients who underwent colorectal cancer surgery did not significantly affect their survival or the detection of cancer recurrence, according to two studies recently published in the Journal of the American Medical Association.  Discuss
