Wayne Forrest[email protected]MRIfMRI finds women recover more slowly from concussions than menA new study published online April 28 in Radiology indicates that women have a more difficult time recovering from concussions than men, based on brain activation patterns seen on functional MRI (fMRI) during working memory tasks. The results hint that more aggressive treatment could be warranted after head injuries in women.April 27, 2015MRIMotion-tracking MRI gives new insight into stroke riskUsing a novel motion-tracking MRI technique, researchers from Johns Hopkins University have uncovered new evidence that reduced function in the left atrium of the heart may be a sign of increased stroke risk in patients with or without atrial fibrillation.April 26, 2015MRIARRS: MR tractography touted as 'reliable' imaging biomarkerDiffusion-tensor MR tractography may be a reliable quantitative imaging biomarker for assessing prostate cancer treatment response to androgen deprivation and radiation therapy, according to a study presented at the American Roentgen Ray Society (ARRS) meeting in Toronto.April 23, 2015Molecular ImagingNEJM: PET for Hodgkin's lymphoma prevents unnecessary radiotherapyA negative PET scan immediately after three cycles of chemotherapy for early-stage Hodgkin's lymphoma can identify patients with an excellent prognosis and avoid unnecessary additional radiation therapy, according to a U.K. study published on 23 April in the New England Journal of Medicine.April 22, 2015MRINEJM: MRI links brain swelling and cerebral malaria deathsAfter three decades of dedication to the care and treatment of children in Malawi who have cerebral malaria, a group of researchers from around the globe for the first time confirmed that brain swelling is the primary reason why some patients die within days from the condition.April 16, 2015Nuclear MedicineChest pain patients do well after ultralow-dose SPECTPatients with chest pain who underwent SPECT myocardial perfusion imaging with an ultralow-radiation-dose gamma camera had no major cardiac events a year later. The research, published in the April issue of the Journal of Nuclear Medicine, indicates that MPI radiation dose can be slashed without adverse clinical impact.April 9, 2015MRIStudy advises MRI screening for high-risk pancreatic cancer patientsSwedish researchers believe that MRI could be the best imaging modality to screen people at high risk of pancreatic cancer, according to an April 8 study in JAMA Surgery. In a small study, they showed how using MRI to screen high-risk individuals found pancreatic lesions in 40% of patients.April 7, 2015MRI3T MRI shows how meniscus tears heal, predicts outcomesMRI at 3 tesla can help forecast the healing potential of a meniscus tear based, in part, on decreased meniscus extrusion, according to a study presented March 28 at a meeting of the American Orthopaedic Society for Sports Medicine.April 7, 2015Molecular ImagingFDDNP-PET gives insight into brain trauma of NFL playersBrain scans with the PET radiopharmaceutical FDDNP of former National Football League (NFL) players who experienced multiple concussions show patterns that are similar to patients who experienced chronic traumatic encephalopathy, according to an April 6 study in the Proceedings of the National Academy of Sciences.April 6, 2015MRILong-term study confirms safety of gadolinium MRI contrast agentAmid persistent concerns over the safety of gadolinium MRI contrast agents, a new study published in the April issue of the American Journal of Roentgenology reinforces the "relatively robust safety profile" of at least one MRI agent. Adverse reactions were tracked over nearly eight years and found to be "infinitesimally small."March 31, 2015Previous PagePage 102 of 239Next PageTop StoriesInterventionalGAE reduces pain biomarkers in knee osteoarthritisGenicular artery embolization (GAE) significantly reduces key biomarkers that drive pain in patients with knee osteoarthritis.Residents/FellowsRace, ethnicity influence educational debt among radiology-bound MDsMRIMRI, CT findings correlate for assessing epicardial fat volumePractice ManagementImaging experts hope NSA enforcement bill delivers on accountabilityCTPET/CT identifies bone demineralization in breast cancer patients
