Circulation: Little radiation risk seen in cardiac scans
August 11, 2014 -- A lack of demonstrated harms combined with significant recent dose reductions have led at least one group of cardiovascular imaging specialists to worry less about the risks of a heart scan and more about the well-being of the patient, according to a new review article in Circulation.
AHRA: For patient satisfaction, focus on right-brain skills
August 11, 2014 -- As the delivery of healthcare shifts to value-based service, radiologists and their practices can't neglect patient satisfaction. To achieve service excellence, it's wise to highlight right-brain skills, according to a talk at the AHRA annual meeting in Washington, DC.
Automated CT tool reveals pulmonary hypertension
August 8, 2014 -- In a new study that used computer-aided analysis, the presence of low normal lung tissue volume correlated with pulmonary arterial hypertension at 3D CT. The technique could offer a more accessible and less invasive diagnostic test than right heart catheterization, according to researchers from Japan.
Canadian policy to improve MRI referrals has mixed results
August 7, 2014 -- A campaign by the Ontario Ministry of Health to reduce inappropriate referrals for lumbar MRI resulted in more-appropriate exams, but it did not lower the number of new referrals, according to a study published in the August issue of the Journal of the American College of Radiology.
Pilot study shows PET/MRI's benefits for large-vessel vasculitis
August 7, 2014 -- Evidence supporting the clinical value of PET/MRI continues to mount, as a small study from Germany has found that the hybrid modality is effective for evaluating patients with large-vessel vasculitis.
Siemens to sell Health Services to Cerner
August 6, 2014 -- Siemens Healthcare has agreed to sell its Health Services business to healthcare information systems firm Cerner for $1.3 billion in cash, transforming the face of healthcare IT by combining the two companies' workforces to become the largest provider in the field.
ICR 2014 organizers use new tactics to lure 5K delegates
August 6, 2014 -- For the first time in its almost 90-year history, the International Congress of Radiology (ICR) will benefit from a fully integrated scientific program with global participation in every session, according to the event organizers. An estimated 5,000 delegates are expected at ICR 2014, to be held in Dubai in September.
Do homework before plugging in CT iterative reconstruction
August 6, 2014 -- Implementing iterative reconstruction on your CT scanner is more than just turning the thing on: You need a careful stepwise approach to get the most out of the radiation dose reduction technology, according to Dr. Jeffrey Mendel. In fact, a full review of your institution's CT protocols could be in order.
Study supports regular mammography screening in older women
August 5, 2014 -- Mammography-detected breast cancer is associated with a shift toward earlier-stage diagnosis in women 75 years and older, subsequently reducing the rate of more advanced, difficult-to-treat cases, according to a new study published online in Radiology.
CT shows Egyptian heart disease hasn't changed in millennia
August 4, 2014 -- CT scans of coronary artery calcium in modern Egyptians revealed that they had patterns of atherosclerosis nearly identical to those of ancient Egyptian mummies -- right down to the affected anatomy, according to a new study in Global Heart.
Study adds evidence linking Alzheimer's to sleep disorders
August 1, 2014 -- PET images with the radiopharmaceuticals FDG and Pittsburgh Compound B have shown a connection between sleep disorders such as sleep apnea and preclinical Alzheimer's among the cognitively normal elderly, according to researchers in New York City.
Straight Talk From the PACSman: Will PACS survive?
July 31, 2014 -- I have been asked time and again if PACS can survive as its own health IT discipline, and I always answer, "Yes, it can." Will it survive, though, is another question entirely, and one that has no easy or clear-cut answer.
Standard mammography image processing best for calcifications
July 31, 2014 -- Standard image processing algorithms help mammography detect calcification clusters more effectively than low-contrast or film-screen algorithms and could reduce false positives, according to a new study published in the August issue of the American Journal of Roentgenology.
