Brain imaging shows memory loss differs by age

Brain imaging shows memory loss differs by age

Health
March 7 (UPI) -- High-resolution brain imaging can be used to show memory proficiency between older and younger adults, according to University of California researchers.Using magnetic resonance imaging, researchers at the University of California, Irvine, found patterns in memory loss during two tests of memory, an object memory task and a location one."This suggests that not all memory changes equally with aging," lead author Zachariah Reagh, who participated in the study as a graduate student at UCI and is now a postdoctoral fellow at UC Davis, said in a press release. "Object memory is far more vulnerable than spatial, or location, memory -- at least in the early stages."As people get older, they often wonder whether its part of the normal part of aging or signs of early stages of a se...

New PET scan imaging agent detects prostate cancer recurrence earlier

March 5 (UPI) -- A new imaging agent that targets copper accumulation in tumors can detect prostate cancer recurrence in patients earlier earlier than current standard methods, researchers in Italy report.In research published in the March issue of The Journal of Nuclear Medicine, researchers compared the results of PET/CT scans to determine the efficacy of screening with copper-64 chloride, a new imaging agent, compared to fluorine-18-choline.Multiparametric magnetic resonance imaging was also performed, and the biodistribution, kinetics of the lesions and radiation dosimetry of the new agent also were evaluated.The recurrence of prostate cancer, which grows slowly, can occur in 30 percent to 90 percent of men, depending on their high risk prostate cancer and the initial treatment the pat...
Study shows there's more time post-stroke to remove clots with new imaging

Study shows there's more time post-stroke to remove clots with new imaging

Health
Jan. 26 (UPI) -- Patients' outcomes from strokes can be improved by removing brain clots several hours longer after the condition than currently performed, according to a study funded by the National Institute of Neurological Disorders and Stroke.The institute, which is part of the National Institutes of Health, presented its findings at the International Stroke Conference in Los Angeles on Thursday and published in the New England Journal of Medicine.The study, called Endovascular Therapy Following Imaging Evaluation for the Ischemic Stroke, or DEFUSE 3, found that performing endovascular therapy -- the physical removal of the blockage -- can be performed up to 16 hours after the symptom compared with the currently approved six hours, because of advanced-imaging technology.The study was c...

£3.4m Pencoed radiology and imaging academy plan unveiled

Health
A new academy to train radiologists and imaging professionals is to be created in Wales with £3.4m of Welsh Government funding. The new National Imaging Academy for Wales will be based in Pencoed, Bridgend, and is due to be up and running by mid-2018. Health Secretary Vaughan Gething will announce the plan on Friday.He said the academy would "play an important role" in helping to increase the number of trained radiologists. It will provide specialist training, in partnership with the existing provision at hospital sites throughout south Wales.Imaging scan trials to target tricky head cancerIt will feature state-of-the-art workstation suites, simulation training and a lecture theatre.
