Preclinical study shows lingering effect of linear GBCAs
November 20, 2018 -- How do different gadolinium-based contrast agents (GBCAs) affect gadolinium retention in the brain? In rats, concentrations of linear GBCAs were several dozen times greater one year after administration than levels of macrocyclic GBCAs, German researchers found in a study published online November 13 in Radiology.  Discuss
MR spectroscopy offers insight into neonates' brain damage
November 19, 2018 -- Proton MR spectroscopy scans of newborns suspected of having brain damage can hasten an early and accurate diagnosis and help determine if they will have severe developmental issues within two years after they are born, according to a study published online on November 14 in Lancet Neurology.  Discuss
Can 7-tesla MRI make the transition to clinical prime time?
November 15, 2018 -- Is 7-tesla MRI ready to stake its claim in the radiology department? Currently, three institutions in the U.S. have begun using 7-tesla magnets for clinical applications, but mostly for neurological and musculoskeletal conditions. The challenge now is showing how much more 7-tesla MRI can contribute to patient care.  Discuss
Artificial intelligence for MRI distinguishes uterine cancer from fibroids
November 15, 2018 -- A machine-learning algorithm for MRI helped clinicians differentiate uterine sarcomas from leiomyomas, according to a study published online November 12 in the European Journal of Radiology. The algorithm could help women avoid unnecessary surgery, concluded the researchers from Iran.  Discuss
MRI depicts brain changes in self-injuring teen girls
November 15, 2018 -- MR images have shown that teenage girls who are prone to injuring themselves have reduced brain volume in two regions. The results suggest the root of the self-harming actions is also biological, rather than solely behavioral, according to a study published online November 5 in Development and Psychopathology.
Is gadolinium deposition disease really a disease?
November 9, 2018 -- Is gadolinium deposition disease really a disease? Italian researchers aren't so sure after they studied patients who received gadolinium-based contrast agents for MRI scans. They reported their findings in a study published online October 30 in Investigative Radiology.  Discuss
MRI reveals mechanics of beatboxing
November 8, 2018 -- Have you ever wondered how performers can so fluidly make those syncopated beatboxing sounds? Researchers have shed some light on the mystery by using real-time MRI to show how motions of the mouth and tongue create different beatboxing sounds and styles.  Discuss
Heart valve-tracking algorithm boosts viability of 4D MRI
November 2, 2018 -- An automated heart valve-tracking algorithm halved the amount of time and variability involved in blood-flow quantification with 4D MRI, according to an article published online October 30 in Radiology. The improved efficiency may help convince clinicians that cardiac 4D MRI is useful for assessing valvular heart disease.  Discuss
2nd MRI center reports problems with Apple devices
November 1, 2018 -- A second imaging facility is reporting problems with Apple devices that appear to be related to the operation of the center's MRI scanner. Nearly 10 late-model Apple iPhones and Watches were permanently disabled at a Delaware center after it ramped down its MRI magnet.  Discuss
Did MRI helium leak take out hospital's iPhones?
October 31, 2018 -- Social media websites are buzzing with speculation that newer Apple iPhones are susceptible to helium leakage from MRI scanners, based on a recent incident at a hospital near Chicago in which more than three dozen Apple devices stopped working after a scanner installation.  Discuss
