Malta's CT protocol cuts dose, maintains value
June 4, 2015 -- A new CT protocol to scan the head -- as well as the abdomen and thorax -- that reduces patient radiation dose by 24% to 36% and maintains diagnostic efficacy is being used in Malta, following the publication of a study this month.
Concerns emerge about EU radiation safety directive
June 3, 2015 -- Under the new European Directive 2013/59/Euratom, the imaging community and industry will have to adapt regulations, practices, and equipment for a high standard of radiation safety. The European Society of Radiology has now summarized the directive, but some problems remain.
MR fingerprinting returns -- and hopefully disappears again
June 3, 2015 -- Some cardiologists have scientific shortcomings in imaging science, the Maverinck believes. The experiments, methods, and results described went out of date years ago; even dressed in "new clothes" they are inadequate and deficient in precision and accuracy, he writes. Radiologists have their own new clothes: MR fingerprinting.
Know your artifacts to optimize MRI scans
June 2, 2015 -- It's crucial to know the most common artifacts in MRI and try to overcome them, as well as to recognize the diagnostic pitfalls they can mimic, according to researchers from Portugal. They also emphasize that these artifacts can have clinical utility and may assist with a diagnosis.
DTI-MRI may identify early onset of Alzheimer's disease
June 1, 2015 -- Using diffusion-tensor MRI (DTI-MRI) to identify damaged white matter in the brain may help pinpoint the early onset of Alzheimer's disease, as well as the start of two atypical forms of the condition, according to a new Dutch study published online May 27 in Radiology.
Last-minute deal averts strike in Vienna
May 29, 2015 -- VIENNA - Medical staff at Vienna's general hospital have voted overwhelmingly to support a strike, according to results announced on Thursday, but a walkout is unlikely after doctors clinched a last-minute agreement that includes higher pay and additional support staff.
Analysis finds variance in uptake of amyloid PET tracers
May 28, 2015 -- PET scans can detect varying levels of amyloid in the brain that change with age and the presence of a genotype linked to Alzheimer's disease, according to a Dutch study in the May Journal of the American Medical Association. The findings may enable clinicians to better tailor which patients receive the scans.
Specialist imaging search tool shows promise
May 27, 2015 -- Radiologists increasingly face information overload in their interpretation tasks, but a medical image retrieval system combining text-based searches and content-based image retrieval techniques is assisting more of them.
Study finds higher breast recall rates in U.S. vs. Denmark
May 27, 2015 -- New evidence has shown that women screened for breast cancer in the U.S. were recalled for workup much more frequently than women screened in Denmark, and cancer detection rates also varied significantly, according to a study published by the International Journal of Cancer.
New breast tomo CAD shows high sensitivity
May 26, 2015 -- A new computer-aided detection (CAD) algorithm for digital breast tomosynthesis studies delivers high sensitivity and an acceptably low false-positive rate, according to Italian researchers. In a retrospective study of nearly 200 women who underwent DBT for breast cancer screening, CAD demonstrated sensitivity of 89% with a false-positive rate of 2.7 per breast.
