Medical physics: Future directions and current status
July 29, 2016 -- Where is medical physics now, and where might it be in 60 years' time? And what have been the key moments in the evolution of medical physics? These questions were addressed in a symposium at London's Imperial College.
Does imaging after thyroid cancer treatment help?
July 28, 2016 -- Yes, surveillance imaging can identify the recurrence of thyroid cancer in patients who have received treatment. But that doesn't mean the scans will affect patient survival, according to a large retrospective study published online July 21 in BMJ.
FDG-PET adds to gallium-68 scans for neuroendocrine tumors
July 21, 2016 -- Follow-up FDG-PET scans can determine which patients with neuroendocrine tumors are suffering from progression of their disease and which of them would benefit from a change in therapy, according to an Austrian study published in the August issue of the European Journal of Nuclear Medicine and Molecular Imaging.
Very low calcium scores do not guarantee negative MPI
July 14, 2016 -- Symptomatic patients with very low coronary artery calcium scores are almost as likely to have a positive SPECT myocardial perfusion imaging (MPI) scan and a subsequent cardiac event as patients with higher calcium scores, according to a study presented at the Society of Nuclear Medicine and Molecular Imaging annual meeting.
MR-guided radiotherapy progresses in lung
July 8, 2016 -- By accounting for the presence of the magnetic field during treatment planning, it is possible to deliver clinically acceptable MR-guided lung stereotactic body radiotherapy treatments, report U.K. researchers. This result may pave the way toward improved radiotherapy treatments.
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.
