Harry Potter's not the only injured quidditch player
June 21, 2017 -- Injuries from the Harry Potter-inspired sport of quidditch are far from make-believe, researchers from Oxford, U.K., have found. Fractures are surprisingly common, and players should consider wearing protective helmets and gloves, they recommended at last week's U.K. Radiological Congress.
MRI shows even moderate drinking harms brain
June 6, 2017 -- MRI results have revealed that even moderate drinking is linked to declines in brain health. The results of the 30-year study have important public health implications because alcohol consumption affects such a large percentage of the population, concludes a new study in BMJ.
Italians show how to succeed at 7T MRI of knee
June 5, 2017 -- Ultrahigh-field MRI -- and specifically 7-tesla MRI -- now is a clinically viable method for studying knee cartilage, thanks in large part to the development of a custom-built volume coil, according to researchers from Pisa University Hospital in Italy.
Which is best: CT- or MR-guided radiotherapy?
June 1, 2017 -- Image guidance using cone-beam CT can increase the accuracy of proton therapy and improve outcome, but the emergence of online MR-guided radiotherapy promises unparalleled soft-tissue image contrast and the ability to "see what you treat." So which technique is better?
RoeKo: Macrocyclic contrast shows no signal changes
May 31, 2017 -- A new study of pediatric MRI safety in the brain presented at the 98th German Radiology Congress (Deutscher Röntgenkongress, RöKo 2017) has added to the mounting evidence supporting the superior safety of macrocyclic gadolinium-based contrast agents when compared with linear MRI contrast.
Fast cardiac MR scan can boost patient care
May 26, 2017 -- A fast and relatively cheap cardiovascular MR (CMR) scan is a cost-effective way to scan large volumes of patients with a wide range of suspected heart conditions, said researchers from Peru in a presentation on 26 May at the EuroCMR 2017 meeting in Prague.
FDA finds no health effects from gadolinium retention
May 25, 2017 -- There is no evidence that gadolinium remaining in the body after MRI contrast administration has any negative health effects, according to a review published on 22 May by the U.S. Food and Drug Administration (FDA). The announcement is unlikely to settle the debate over gadolinium contrast safety, however.
MRI shows true value in invasive placenta
May 22, 2017 -- Further evidence of MRI's ability to confirm suspected placental anomalies or to assist in cases of equivocal ultrasound findings has come from Saudi Arabia. A study of pregnant women found that noncontrast MRI is a sensitive diagnostic test for detecting invasive placenta.
Gadolinium dosing calculator can guide MRI contrast use
May 18, 2017 -- Given the ongoing concern over the safety of gadolinium-based contrast agents (GBCAs), researchers have developed a resource for MRI technologists and radiologists that calculates accurate and appropriate GBCA doses for patients to avoid dosing errors.
New audit pinpoints causes of 'wasteful' unnecessary scans
May 17, 2017 -- Radiologists' failure to check the validity of requests for CT and MRI scans, along with ignorance among referring doctors of appropriateness criteria for imaging examinations, are the most important reasons for costly inappropriate requests of radiological exams, a new study from Saudi Arabia found.
