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.
CT scans validated for immune-related colitis
April 5, 2017 -- CT is a reliable modality for diagnosing immune-related colitis, replacing invasive colonoscopy with high diagnostic accuracy and a safer profile, according to research published April 3 in Cancer Immunology Research.
CT radiation dose falls over time, but still varies widely
April 4, 2017 -- CT radiation dose dropped a little over the course of a large seven-year study of patients undergoing repeat scans. But just as noteworthy were large variations in dose for repeat procedures in the same patients over time, researchers concluded in a paper published March 28 in the American Journal of Roentgenology.
ACC: CT detects blood clots that reduce valve motion
March 20, 2017 -- CT detects small clots surrounding valve leaflets after transcatheter aortic valve replacement that are missed on echocardiography studies, concludes new research presented at the just-concluded American College of Cardiology (ACC) meeting in Washington, DC. Reduced valve motion after the procedure may be a sign of the condition, the researchers said.
Counseling visits help patients understand CT screening
March 15, 2017 -- Individuals who completed counseling visits prior to CT lung cancer screening exams demonstrated greater knowledge of the studies after the sessions, including a better understanding of screening's benefits and harms, according to a study published in the March edition of Chest.
Which orthopedic imaging options are the safest?
March 15, 2017 -- Pediatric orthopedic imaging patients who need surgery often receive more x-rays and CT scans than nonsurgical patients, and orthopedic surgeons should seek options to reduce radiation exposure, according to research being presented this week at the American Academy of Orthopaedic Surgeons 2017 annual meeting.
CTA plus stress tests help predict heart attacks
March 14, 2017 -- CT angiography (CTA) and CT stress myocardial perfusion imaging (MPI) can help predict heart attacks -- and offer the benefit of being less invasive than the traditional combination of coronary angiography and SPECT MPI stress tests, according to a study published online March 14 in Radiology.

6 tips for joining a CT lung cancer screening registry

On February 5, 2015, the U.S. Centers for Medicare and Medicaid Services (CMS) issued a national coverage determination (NCD) that found the evidence is sufficient to permit high-risk patients to receive annual low-dose CT (LDCT) scans for lung cancer screening without cost sharing. Read more
