AI can differentiate parkinsonism on DWI-MRI
September 13, 2019 -- An artificial intelligence (AI) algorithm can distinguish between parkinsonian syndromes on diffusion-weighted MRI (DWI-MRI) exams at an accuracy level comparable to that of current gold-standard methods, according to research recently published online in Lancet Digital Health.  Discuss
PET, MRI link amyloid plaque with swift decline
September 12, 2019 -- Patients whose PET and MR images show beta-amyloid plaque accumulation in the brain experience a significantly faster path toward dementia than people with vascular dementia and no plaque deposits, according to a study published online September 11 in Neurology.  Discuss
Advanced MRI technique confirms dementia risk
September 12, 2019 -- U.K. researchers have developed a unique diffusion-tensor MR imaging algorithm to identify which patients with stroke-related small-vessel disease could progress to cognitive decline and possible dementia, according to a study published online September 12 in Stroke.  Discuss
MRI helps predict outcomes of endometriosis surgery
September 12, 2019 -- MRI can predict the severity of endometriosis in women referred for surgery when it is used as a complement to transvaginal ultrasound, according to a study published online September 10 in Ultrasound in Obstetrics & Gynecology.  Discuss
Ga-68 PSMA PET/MRI, mpMRI work for prostate cancer analysis
September 12, 2019 -- Prostate cancer patients at intermediate or high risk of advanced disease can benefit from either gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) PET/MRI or multiparametric MRI (mpMRI) alone to diagnose specific features of their disease, according to a study published September 10 in Radiology.  Discuss
MS patients show signs of gadolinium retention on MRI
September 10, 2019 -- Seeing is believing for Italian researchers who used MRI to visually confirm evidence of gadolinium retention in patients with multiple sclerosis (MS). Their study included patients who had undergone several MRI scans with a gadolinium-based contrast agent. The findings were published September 4 in Insights into Imaging.  Discuss
MRI joins PET to better diagnose large-vessel vasculitis
September 5, 2019 -- To evaluate large-vessel vasculitis, two modalities are better than one. A dual-modality approach worked well for French researchers who combined PET and MRI to improve their analysis of vasculitis abnormalities in a study published August 27 in Scientific Reports.  Discuss
Cancer deaths eclipse heart disease in developed world
September 4, 2019 -- Cancer is now the leading cause of death in high-income countries, with twice as many people dying from cancer than heart disease in these nations. Heart disease continues to be the main cause of death in less prosperous countries, according to data presented at this week's European Society of Cardiology meeting in Paris.  Discuss
German study finds trace gadolinium in fast-food drinks
August 29, 2019 -- Soft drinks served at fast-food outlets in a half-dozen cities in Germany had trace levels of gadolinium from MRI contrast agents, according to a recent study. While the research highlights the persistence of gadolinium in the environment, the levels most likely do not represent a health risk, experts say.  Discuss
3D MRI enables contrast-free evaluation of cardiac strain
August 29, 2019 -- Researchers from the U.K. have developed a new 3D MRI technique for calculating heart muscle strain. They discuss how their method may help improve the accuracy of quantifying cardiac health without the need for gadolinium contrast in an article published online August 28 in Scientific Reports.
