New-generation dual-source CT heart scans prove fast and sharp
July 22, 2014 -- Operating the new third-generation dual-source CT scanner 24/7 has revealed a rapid system with robust imaging capabilities and an array of new features to perform heart scans at low doses, according to researchers from a leading German facility.
'Tiered' CT approach shows promise in coronary disease
July 22, 2014 -- In patients with stable angina and suspected coronary disease, a "tiered" approach to CT imaging finds -- so far at least -- that calcium scoring is all many patients need. That's right, for most patients there's simply no need to start with the big imaging guns, researchers in Rotterdam report.
4D peripheral CT often beats dynamic MRI
July 21, 2014 -- Pinpointing flow problems in the peripheral arteries is a task that is typically handed over to dynamic MR angiography. But often, bone-subtracted 4D CT angiography can do a better job, according to German researchers.
MRI links antipsychotic drugs to brain loss
July 21, 2014 -- MR images of patients with schizophrenia have confirmed that antipsychotic drugs can lead to a decrease in brain volume, but the drugs do not appear to cause adverse cognitive issues. The study also found that the rate of brain loss was greater when the dose of medication was higher.
Market matters: Health information exchange
July 18, 2014 -- Barriers continue to exist across Europe for healthcare IT adoption, but there are tangible benefits for radiologists and patients alike on the horizon. Based on a new study, analyst Stephen Holloway discusses how large-scale IT infrastructure is shaping the future of medical imaging.
Dutch use shimming to enhance value of MRI-linac unit
July 17, 2014 -- Only a handful of groups are developing hybrid MRI-linac systems for cancer treatment, but interest in this area looks set to grow after researchers from the Netherlands showed that shimming allows a system to acquire images with good geometric fidelity for all static gantry positions.
French MRI waiting times are 'worst in a decade'
July 16, 2014 -- The shortage of MRI equipment in France is becoming increasingly alarming, and many patients have to wait almost 40 days to undergo an examination, the longest delay in the past 10 years, according to new data. This report highlights a disaster, said a respected senior radiologist from Paris.
Actionable reports and the teleradiology debate
July 16, 2014 -- Technology has transformed radiologists' reporting practices, allowing for flexible working and sharing of workloads, but this should not compromise a radiologist's ability to provide actionable reports. Face-to-face dialogue remains a key factor, writes Dr. Neelam Dugar.
MRI use linked to patient mortality in Irish study
July 15, 2014 -- A new study of MRI use at a hospital in Ireland paints a complex picture of the modality, with higher in-hospital mortality and longer hospital stays for patients who got MRI scans. However, this could be because the patients were more acutely ill, according to an article in the July Journal of the American College of Radiology.
Ultrasound visualizes odor perception in brain
July 15, 2014 -- A neurofunctional ultrasound method can provide in vivo visualization of odor perception in the brain, shedding light on the functioning of the olfactory system, researchers from France reported in an article published in NeuroImage.
German-led team develops novel x-ray phase-contrast method
July 14, 2014 -- Using a laboratory source with unprecedented brightness, scientists from three European institutions have found a way to achieve high-quality x-ray phase-contrast imaging with lower radiation dose. A major goal is to find clinical applications, including cancer diagnosis and osteoporosis.
ESTI: New 3D tool displays promise for rib evaluations
July 14, 2014 -- An automated curved planar reformatting software tool that presents the ribs in an "unfolded" view is starting to prove its clinical value, according to a presentation at the European Society of Thoracic Imaging (ESTI) annual meeting, held last month in Amsterdam.
Rotterdam group helps gauge coronary disease severity
July 14, 2014 -- At the same time that a validated fractional flow reserve CT angiography application seems to be nearing U.S. Food and Drug administration approval, a new contender for gauging the severity of coronary disease at CT is pushing its way into the ring. Furthermore, it promises to be a simpler solution, according to a team of Dutch researchers.
