ACR 2017: Radiation dose varies in head CTs of children
May 23, 2017 -- A large analysis of pediatric head CT scans across the U.S. showed surprisingly large variations in radiation dose that increased as children grew older, according to results presented at this week's American College of Radiology (ACR) meeting in Washington, DC.
Deep learning for lung cancer advances goals
May 11, 2017 -- SAN JOSE, CA - Deep-learning algorithms based on convolutional neural networks are advancing a number of cherished goals in lung cancer analysis that will soon help patients live longer -- and even predict how long they might expect to live, according to a May 10 talk at the NVIDIA GPU Technology Conference.
Ottawa Hospital slashes lung cancer treatment time
May 8, 2017 -- What's the best way to reduce time to treatment for patients with abnormal CT scans who are referred for suspected lung cancer? The radiology department at a Canadian hospital was able to cut the time to treatment in half for referred patients, according to a presentation at last month's Canadian Association of Radiologists meeting in Montreal.
Diagnostic reference levels reduce CT doses
May 5, 2017 -- Establishing diagnostic reference levels (DRLs) for radiation dose is a powerful tool for reducing radiation exposure in CT, according to a study by Canadian researchers published in the May issue of the American Journal of Roentgenology.
ARRS: Do NLST results translate to the real world?
May 4, 2017 -- NEW ORLEANS - When the National Lung Screening Trial (NLST) in 2011 reported a 20% lung cancer mortality reduction for high-risk smokers who were screened annually with low-dose CT, professional organizations lined up behind CT lung screening. But does the patient population studied in the NLST reflect the real world?
Photon-counting breast CT shows promise
April 27, 2017 -- Tests of a prototype photon-counting detector breast CT scanner show that the system could be useful as an adjunct to low-dose breast CT by separating the energy levels of different types of materials within the breast to assess tissue composition and improve cancer diagnosis.
Lung-RADS category 4X helps diagnose lung cancer
April 20, 2017 -- The addition of category 4X lesions in the Lung CT Screening Reporting and Data System (Lung-RADS) imaging scheme adds value and increases malignancy yields among experienced radiologists, according to a study in Radiology. The 4X nodules turn out to be malignant in half of cases.
Should ultrasound replace CT for asymptomatic hematuria?
April 18, 2017 -- The combination of renal ultrasound and cystoscopy is the most cost-effective strategy for evaluating patients with asymptomatic microscopic hematuria, potentially saving hundreds of millions of dollars compared with CT and cystoscopy, according to research published online April 17 in JAMA Internal Medicine.
6 tips for joining a CT lung cancer screening registry
April 17, 2017 -- Imaging facilities across the U.S. are beginning to provide CT lung cancer screening -- and they are getting Medicare payment for it as well. But to get paid, you have to participate in a CT lung cancer registry. In this article, Judy Burleson of the American College of Radiology offers six tips for getting started.
Sharing best practices cuts CT dose substantially
April 14, 2017 -- Substantial reductions in CT radiation dose can be achieved by monitoring and comparing dose across institutions -- even in a large academic health network such as the University of California. Getting buy-in from all the players involved is key, according to a study published online April 10 in JAMA Internal Medicine.
