Ultrasound eases drug delivery to the brain
June 30, 2016 -- Brain diseases are notoriously difficult to treat due to the blood-brain barrier (BBB), a protective layer of cells limiting the delivery of most drugs into the brain. One promising approach for BBB disruption combines pulsed ultrasound with injected microbubbles.
PET shows tau may be Alzheimer's catalyst
June 27, 2016 -- In a comparison of PET images with three different radiotracers, German researchers found that tau deposits may be more influential in causing Alzheimer's disease than amyloid accumulation, according to results presented at the Society of Nuclear Medicine and Molecular Imaging meeting.
German team wins prestigious Image of the Year award
June 17, 2016 -- SAN DIEGO - German researchers have received this year's Image of the Year award from the Society of Nuclear Medicine and Molecular Imaging (SNMMI) for the use of three different radiotracers with PET to measure amyloid plaques, tau tangles, and metabolic activity in the brains of living Alzheimer's patients.
Debate focuses on how medical physicists improve therapy
June 3, 2016 -- When introducing new treatment technologies, medical physicists are faced with a tricky balance between quality and safety. But how can they help improve treatment quality? This question was addressed by Håkan Nyström, PhD, chief physicist at the Skandion Clinic in Uppsala, Sweden.
FDG-PET helps accurately assess unconscious patients
May 27, 2016 -- European researchers have developed a way to use FDG-PET to measure glucose metabolism in patients with severe brain injuries to diagnose and predict when they will recover consciousness, according to a study published online on 26 May in Current Biology.
Hurdles remain for image-guided robotic prostatectomy
May 19, 2016 -- Dutch researchers are using a novel approach to radical prostatectomy by combining a hybrid imaging agent with SPECT/CT to detect lymph nodes and guide robot-assisted surgery, according to a study in the July issue of the European Journal of Nuclear Medicine and Molecular Imaging.
Software as good as hardware for PET gating
May 19, 2016 -- Researchers have demonstrated that software is as good as, if not better than, hardware when it comes to filtering out patient motion during PET. In blind tests, reviewers could spot no difference most of the time, and when differences were seen, software gating was more likely to be rated as superior.
Swiss presenters come out top in ECR survey
May 18, 2016 -- Swiss, Dutch, French, and German speakers who present at ECR have the highest conversion rate into publications, while the profiles of researchers from Japan, Korea, China, and India are rising fast, according to a new study.
Cardiac MRI beats SPECT for predicting heart events
May 12, 2016 -- Cardiovascular MRI is a better prognosticator of risk for serious cardiovascular events than SPECT, regardless of a person's risk factors, angiography results, or initial treatment, according to a study published online in the Annals of Internal Medicine.
U.K. releases new guidelines on PET/CT
May 11, 2016 -- The U.K. Royal College of Radiologists (RCR) and Royal College of Physicians have issued revised recommendations on the best use of PET/CT. The 34-page document can be downloaded free of charge from the RCR's website, and it includes a comprehensive bibliography.
