MRI reveals key brain differences in people with genetic autism
August 8, 2017 -- With the aid of MRI and machine learning, researchers have identified structural brain abnormalities that correspond with cognitive and behavioral deficiencies in people with common genetic causes of autism spectrum disorder, according to a new study published online August 8 in Radiology.  Discuss
PAWS program achieves sedation-free pediatric MRI scans
August 4, 2017 -- MRI can be scary for pediatric patients, but Vanderbilt Children's Hospital in Nashville, TN, has found that a little extra attention can go a long way toward easing fears. A Vanderbilt initiative called Patients Awake While Scanned (PAWS) has helped nearly all young patients to complete MRI scans without sedation.  Discuss
Machine learning predicts pregnancies with fetal growth restriction
August 3, 2017 -- Making use of 3D MRI features, a machine-learning algorithm can accurately predict pregnancies with fetal growth restriction, potentially opening up opportunities for interventions to protect vulnerable fetuses, according to research published online in the Journal of Magnetic Resonance Imaging.  Discuss
Luminal water MRI could be best for prostate cancer
July 31, 2017 -- Researchers from the University of British Columbia are reporting early success in developing a novel T2-based MRI technique that uses water content in prostate tissue to detect and grade cancer. The method outperformed several other MRI parameters, according to a study published in the August issue of Radiology.  Discuss
Neonates show no adverse effects from CT, MRI contrast
July 27, 2017 -- A review of inpatient neonates suggests that babies with normal renal function who receive iodine-based CT or gadolinium-based MRI contrast agents have no greater risk of renal toxicity than those not receiving contrast, according to results published in the August issue of Radiology.  Discuss
EMA confirms clampdown on linear gadolinium agents
July 21, 2017 -- It's official: After months of intense lobbying and wrangling, the use of some linear gadolinium contrast agents in MRI will be restricted, and others are to be pulled from the market, following confirmation on Friday that the European Medicines Agency (EMA) has approved recommendations made on 7 July by the Pharmacovigilance Risk Assessment Committee.  Discuss
Pediatric patient sedation on the rise at one ACO
July 21, 2017 -- A four-year survey of more than 18,000 MRI scans within the Partners for Kids accountable care organization (ACO) showed an increasing need to anesthetize pediatric patients undergoing MRI scans, according to results published in the July issue of the Journal of the American College of Radiology.  Discuss
fMRI, EEG may detect consciousness in TBI patients
July 20, 2017 -- Researchers from Massachusetts General Hospital are using the novel approach of combining functional MRI (fMRI) and electroencephalography (EEG) to determine the level of consciousness in intensive care unit patients with severe traumatic brain injury (TBI), according to a study published online July 20 in Brain.  Discuss
Gadolinium found in animal tissue regardless of GBCA type
July 18, 2017 -- Contrary to previous research, a prospective animal study has confirmed the presence of gadolinium deposits in brain tissue after the injection of both linear and macrocyclic gadolinium-based contrast agents (GBCAs), according to results published online in Radiology.  Discuss
DWI-MRI shows vision changes could predict Parkinson's
July 12, 2017 -- With the help of diffusion-weighted MR imaging (DWI-MRI), researchers in Italy have uncovered changes in the visual systems of patients newly diagnosed with Parkinson's disease, according to a study published online July 11 in Radiology.  Discuss
