DWI-MRI can solve pediatric arthritis with no contrast
March 16, 2020 -- Diffusion-weighted MR imaging (DWI-MRI) has proven accuracy in diagnosing and evaluating children with suspected arthritis and can help clinicians avoid the use of gadolinium-based contrast agents, according to a study published March 10 in Radiology.  Discuss
AI predicts final infarct lesion for stroke on MRI
March 12, 2020 -- An artificial intelligence (AI) algorithm can predict -- based on baseline MRI and prior to intervention -- the final infarct lesions in patients with acute ischemic stroke, according to research published online March 12 in JAMA Network Open. It can even outperform current clinical prediction methods.  Discuss
MRI shows active leisure time promotes younger brain
March 12, 2020 -- Brain MR images show that older adults who maintain an active lifestyle during their leisure time have more brain volume and age more slowly than their sedentary counterparts, according to a study scheduled to be presented at the upcoming American Academy of Neurology annual meeting.  Discuss
MRI parameters are safe for implanted cardiac devices
March 11, 2020 -- If imaging centers adhere to standard MRI parameters for static, gradient, and radiofrequency magnetic fields, implanted cardiac devices will continue to function smoothly during an MRI scan, according to a study published March 3 in Radiology.  Discuss
AI can help diagnose bipolar disorder on MRI exams
March 11, 2020 -- Artificial intelligence (AI)-based analysis of neuroimaging and neurocognitive measures shows promise as a tool for diagnosing bipolar disorder, according to a small proof-of-concept study published online February 26 in the Asian Journal of Psychiatry.  Discuss
Choline-PET boosts mpMRI for prostate cancer detection
March 5, 2020 -- The addition of F-18 choline PET to multiparametric MRI (mpMRI) can significantly improve the detection of higher-risk primary prostate cancer and assessment of patients with suspected cases, according to a study published in the March issue of the Journal of Nuclear Medicine.  Discuss
MRI-targeted biopsy optimizes prostate cancer detection
March 4, 2020 -- MRI-targeted biopsy can greatly improve prostate cancer diagnosis and reduce the chances of patients being either overtreated or undertreated for their disease, according to a study published March 5 in the New England Journal of Medicine.  Discuss
MRI, blood tests could guide care for glioblastoma
March 2, 2020 -- Combining an MRI brain scan with blood test results could become a potent duo in producing clinically relevant information for glioblastoma patients and subsequently direct the most appropriate care for their disease, according to a study published February 27 in Neuro-Oncology Advances.  Discuss
MRI finds gender differences even in healthy hearts
February 27, 2020 -- An investigational 4D flow MRI sequence has helped researchers confirm different blood flow characteristics in the hearts of young, healthy men and women. The findings could help clinicians set benchmarks for comparisons with unhealthy patients, according to a study published February 27 in Radiology: Cardiothoracic Imaging.  Discuss
MRI suggests main reason for psychotic relapses
February 26, 2020 -- MR images have revealed decreased cortical thickness in people on antipsychotic drugs compared with those on placebo. But in both cases, their relapse back into psychosis may be due more to structural brain change than a lack of medication, according to a study published February 26 in JAMA Psychiatry.  Discuss
