Contrast-enhanced mammo effective in detecting breast lesions
April 25, 2014 -- While contrast-enhanced spectral mammography is a relatively new technique, two Egyptian studies are showing the advantage of using the technology for the detection of breast lesions, and compare it favorably with more established imaging modalities.
CMS publishes agenda for April 30 CT lung screening meeting
April 24, 2014 -- The U.S. Centers for Medicare and Medicaid Services (CMS) has released detailed information in preparation for the April 30 meeting of the Medicare Evidence Development and Coverage Advisory Committee to review the evidence on CT lung cancer screening.
Efficiency, personalized medicine will drive CAD forward
April 24, 2014 -- Clinical adoption of computer-aided detection (CAD) software has plateaued and has largely been confined to mammography. To change that, next-generation CAD software will need to deliver efficiency gains, interactivity, and algorithms that are personalized for patients, according to Dr. Eliot Siegel of the University of Maryland.
Report: Cardiology, neurology could fuel bright future for PET
April 24, 2014 -- The diversification and expansion of PET imaging into cardiology and neurology are two applications expected to propel growth in PET procedure volume and equipment purchasing over the next several years, according to a new market research report from Bio-Tech Systems.
Ambulance with mobile CT cuts stroke treatment times
April 23, 2014 -- An ambulance equipped with a mobile CT scanner and thrombolysis equipment reduced treatment times for stroke patients without a corresponding increase in adverse events, according to a study published by German researchers in the Journal of the American Medical Association.
Residents value overnight attendings, but crave independence
April 23, 2014 -- Radiology residents are of two minds when it comes to night call, according to the results of a new survey in Academic Radiology. They want the peace of mind that comes with knowing an attending radiologist is on duty to help with tough cases, but they also hunger for the freedom to make a "hot call" on tough cases without help.
JAMA IM: Mammo false positives don't create long-term anxiety
April 22, 2014 -- Mammography false positives are considered to be one of the harms of regular breast cancer screening. But receiving false-positive results doesn't seem to affect women's long-term anxiety -- and, in fact, may boost their intention to continue screening, according to a new study published online in JAMA Internal Medicine.
BMI tied to soft plaque at CCTA in diabetes patients
April 22, 2014 -- A new study of diabetes patients shows a direct relationship between body mass index (BMI) and the soft coronary artery plaques found on coronary CT angiography (CCTA) that portend a high risk for coronary events, according to research published online in Radiology.
CCTA plus stress CT MPI boosts diagnosis of high-risk patients
April 21, 2014 -- Combining coronary CT angiography (CCTA) and stress CT myocardial perfusion imaging (MPI) improves the evaluation of coronary artery stenosis in high-risk patients, reducing the number of false positives and potentially the number of unnecessary interventions, according to new research from the Medical University of South Carolina.
CAD detects retained surgical items on radiographs
April 21, 2014 -- Retained surgical items after surgery can be a significant source of mortality, morbidity, and cost. Computer-aided detection (CAD) technology can help prevent these costly errors, however, according to a group from the University of Michigan Health System.
Radiation dose safety: Filtering the message from the noise
April 18, 2014 -- Patient radiation dose safety is a hot topic in the imaging industry and media. But as often happens when a subject is hot, the radiation safety information pool has become muddied with disparate and conflicting information. Neil Singh from Ascendian Healthcare Consulting helps filter the true message in radiation safety from the industry noise.
MRI finds loss of brain volume in older, apathetic adults
April 17, 2014 -- MRI scans have revealed that older adults with bouts of apathy may have smaller volumes of gray and white matter in areas of the brain associated with learning, memory, and internal communication, according to a study published online April 16 in Neurology.
