Perfusion imaging expands window for stroke treatment
January 25, 2018 -- Perfusion MR and CT images can help clinicians identify stroke patients who could benefit from therapy later than previously thought -- up to 16 hours after the event, according to a study published online January 24 in the New England Journal of Medicine.  Discuss
Machine learning predicts working-memory performance
January 23, 2018 -- Can the combination of a machine-learning algorithm and diffusion MRI metrics of brain white-matter microstructure serve as a useful method for the early prediction of working-memory impairment? It appears possible, according to recent research from NYU Langone Medical Center in New York City.  Discuss
Artificial intelligence, brain MRI aid kids with hearing loss
January 15, 2018 -- U.S. and Chinese researchers have developed a machine-learning algorithm that analyzes MRI brain scans to predict how well deaf children may be able to develop language skills after receiving a cochlear implant, according to a study published online January 15 in the Proceedings of the National Academy of Sciences.  Discuss
3T MRI fetal scans should not affect newborns' hearing
January 12, 2018 -- When pregnant mothers are scanned with 3-tesla MRI, the higher noise levels relative to 1.5-tesla scanners do not seem to increase the risk that their babies will have hearing problems after birth, according to new research from Boston Children's Hospital and the Children's Hospital of Philadelphia.  Discuss
CMS to ease rules for MRI scans of implantable devices
January 11, 2018 -- Reimbursement could soon get a lot easier for MRI scans of patients with implantable cardiac devices. The U.S. Centers for Medicare and Medicaid Services (CMS) on January 11 proposed withdrawing its requirement that payments for these scans only be made when the scans are performed within a clinical study.  Discuss
3D-printed breast biopsy device boosts accuracy
January 10, 2018 -- Researchers from the Netherlands have developed a 3D-printed robot-guided device capable of facilitating MR-guided breast biopsy and improving the accuracy of breast cancer diagnosis. Biopsies can even be performed inside the MRI scanner.  Discuss
Multiparametric MRI can help avoid renal mass biopsies
January 10, 2018 -- Researchers at the University of Texas Southwestern have discovered that radiologists using multiparametric MRI have an 80% chance of detecting clear cell carcinoma in the kidneys without the need for a confirming biopsy. In addition, the technique was successful among radiologists with varying levels of expertise.  Discuss
MRI links function of brain networks to IQ
January 5, 2018 -- A person's intelligence could soon be confirmed with an MRI scan to assess how well connected and functional his or her neurological networks are, according to a study published in the January issue of Neuron.  Discuss
NEJM: No long-term effects on cardiac devices with MRI
January 2, 2018 -- There's good news for patients with cardiac devices who are about to undergo an MRI scan. Researchers found no long-term clinically significant adverse events with the devices in a study of more than 1,000 scans, according to results published in the December 28 issue of the New England Journal of Medicine.  Discuss
Gadolinium in fetuses almost entirely cleared via placenta
January 2, 2018 -- Only trace amounts of the gadolinium administered to pregnant monkeys cross the placenta and enter the fetuses, and most of this gadolinium quickly returns back to the mother's bloodstream for excretion, according to research published in the January issue of Radiology.  Discuss
