Group creates 3D printed heart with CT, echo data June 29, 2015 -- In what they are calling a major advance, researchers from Michigan have created a 3D model of a human heart using data from two separate cardiac imaging techniques: CT and echocardiography. They believe that such hybrid 3D models will be more accurate than those created from just one imaging modality.
CT lung CAD may require adjustment from radiologists June 26, 2015 -- Computer-aided detection (CAD) for CT lung exams will be essential in the coming era of population-based lung cancer screening. But radiologists may have to change their way of reading studies to reap its benefits, according to a recent talk by Dr. Geoffrey Rubin from Duke University.
Nonsolid nodules can be safely managed with CT June 23, 2015 -- Patients with nonsolid lung nodules can be safely managed noninvasively using low-dose CT, according to an analysis published online June 23 in Radiology of more than 57,000 lung cancer screening patients.
Are imaging sites ready for new Joint Commission rules? June 22, 2015 -- On July 1, a new era of intense scrutiny and documentation will arrive for CT and other imaging modalities, thanks to new Joint Commission accreditation requirements that become effective on that date. Unfortunately, most radiology departments aren't remotely ready to fulfill the requirements, according to a talk at the International Symposium on Multidetector-Row CT.
Lung disease goes undiagnosed in many smokers June 22, 2015 -- More than half of long-term smokers who pass lung-function tests are actually living with lung disease that remains undiagnosed, according to a study published online Monday in JAMA Internal Medicine.
PACS replaces planes for image transfer in Arctic June 17, 2015 -- A remote spot in an eastern Arctic region of Canada that is closer to Greenland than Toronto has received its first CT scanner, as well as a PACS and satellite link to go with it. The new technologies are revolutionizing healthcare in the region, as images no longer need to be transported by cargo plane to the southern part of the country.
USPSTF ponders addition of new heart risk factors June 12, 2015 -- The U.S. Preventive Services Task Force (USPSTF) has drafted a research plan for assessing cardiovascular disease risk, and it is accepting public comments on the idea of adding nontraditional measures such as coronary artery calcium into standard cardiovascular risk factor assessment for asymptomatic individuals.
MDCT: In CT lung cancer screening, don't forget the heart June 11, 2015 -- SAN FRANCISCO - Radiologists who screen smokers for lung cancer with CT should remember to look at the heart as an important predictor of mortality in its own right, according to a Tuesday talk at the International Symposium on Multidetector-Row CT (MDCT).
Annals: Few differences in CCTA vs. SPECT MPI June 11, 2015 -- A study comparing coronary CT angiography (CCTA) with SPECT myocardial perfusion imaging (MPI) in chest pain patients found that CT's radiation dose was lower and that it yielded fewer unpleasant experiences among patients, according to results published in the Annals of Internal Medicine.
