MRA is cost-effective for kidney disease-related aneurysms
February 21, 2019 -- Optimizing costs with beneficial patient outcomes is a constant goal in healthcare. In that regard, the use of MR angiography (MRA) to screen and follow up patients who may have intracranial aneurysms linked to kidney disease can work well from both cost and clinical perspectives, according to a study published online February 19 in Radiology.  Discuss
MRI measurements can change Parkinson's diagnosis
February 20, 2019 -- With a tweak to a proven MRI method for measuring certain brain regions, Italian researchers have eased the difficult task of differentiating between Parkinson's disease and progressive supranuclear palsy with parkinsonism. Results of their study were published online February 13 in Movement Disorders.  Discuss
Targeted MRI signal could provide insights to psychosis
February 20, 2019 -- Results of a type of MRI protocol called neuromelanin-sensitive MRI (NM-MRI) could help diagnose psychosis and provide an indicator of psychosis severity, according to a study published February 18 in the Proceedings of the National Academy of Sciences.  Discuss
AI algorithm predicts Alzheimer's disease progression
February 19, 2019 -- An artificial intelligence (AI) algorithm can predict the progression of Alzheimer's disease by analyzing a combination of demographic and neuroimaging data, as well as information on cerebrospinal fluid and cognitive performance biomarkers, according to research published online February 13 in Scientific Reports.  Discuss
MRI should be 1st choice for pediatric appendicitis
February 18, 2019 -- Look no further than MRI to confirm suspected cases of acute appendicitis in children or to provide an alternative diagnosis, according to a study published online February 12 in Radiology.  Discuss
fMRI gauges procedure to reduce PTSD pain
February 14, 2019 -- Could vagus nerve stimulation help ease pain from post-traumatic stress disorder (PTSD)? Functional MRI (fMRI) scans provided an affirmative answer by showing reduced activity in brain regions linked to pain processing in a study published online February 13 in PLOS One.  Discuss
Gadolinium in gliomas, adjacent tissue raises questions
February 12, 2019 -- Researchers have discovered the presence of gadolinium from MRI contrast in gliomas, as well as neighboring normal brain tissue and necrosis. The findings are contributing to the body of knowledge regarding the retention of trace elements from gadolinium-based contrast agents (GBCAs), according to a study published online February 2 in Neuroradiology.  Discuss
Underutilized cardiac MRI stress test predicts mortality
February 8, 2019 -- A stress test with cardiac MRI can do more than simply assess heart function. The modality's findings can also predict which patients are most likely to have a fatal outcome within five years, according to a study published online February 8 in JAMA Cardiology.  Discuss
AI singles out high-risk prostate cancer on mpMRI
February 8, 2019 -- Working with radiomics data on multiparametric MRI (mpMRI) scans, an artificial intelligence (AI) algorithm was able to distinguish between low-risk and high-risk prostate cancer more accurately than the current risk assessment approach used by radiologists, according to research published online February 7 in Scientific Reports.  Discuss
Advanced imaging offers insight into targeted therapies
February 6, 2019 -- Major breakthroughs are emerging in the development of targeted therapies that use the body's own immune system to attack cancer cells. But traditional methods of measuring the success of drug candidates are slow and expensive. Could advanced imaging help? Diana Roettger, PhD, and Olga Kubassova, PhD, of the Image Analysis Group offer a perspective.  Discuss
