Chest pain patients do well after ultralow-dose SPECT April 10, 2015 -- Patients 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.
FDDNP-PET gives insight into brain trauma of NFL players April 7, 2015 -- Brain 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.
ACR, SNMMI set standards for reading PET/MRI brain scans March 19, 2015 -- The American College of Radiology (ACR) and the Society of Nuclear Medicine and Molecular Imaging (SNMMI) have released the first in a series of requirements for physicians and clinicians interested in gaining proficiency in reading PET/MRI scans.
ACC: PET/CT trumps SPECT for cardiac studies March 17, 2015 -- Researchers from Utah found that PET/CT is far superior to SPECT for diagnosing myocardial ischemia, with higher sensitivity at a lower radiation dose, according to a paper presented on Sunday at the American College of Cardiology (ACC) meeting in San Diego. PET/CT in particular far outstripped SPECT in determining that patients were free of cardiac disease.
Adults at low risk of heart disease shouldn't get screening March 16, 2015 -- Cardiac screening shouldn't be performed on patients at low risk for coronary heart disease, as it doesn't improve patient outcomes and comes with potential harms due to false-positive results, according to a paper published on Monday in the Annals of Internal Medicine by the American College of Physicians.
New indications, added funding power Navidea into the future March 16, 2015 -- The past six months have brought many substantial changes for radiopharmaceutical developer Navidea Biopharmaceuticals. The company's accomplishments range from new grant funding to expanded regulatory indications for its main product.
Canadian group succeeds with cyclotron-produced Tc-99m March 10, 2015 -- Researchers from Centre de Recherche of the Hospitalier Universitaire de Sherbrooke, working in conjunction with the University of Alberta and Advanced Cyclotron Systems, have achieved a major advance by affirming that use of cyclotron-produced technetium-99m (Tc-99m) results in image quality equivalent to that of Tc-99m manufactured in a nuclear reactor.
The big question: CT, MRI, or nuclear for coronary artery disease diagnosis? March 7, 2015 -- Faced with a choice of CT, MRI, and hybrid nuclear imaging for the diagnosis of coronary artery disease, which modality is most suitable for any one patient type and why? All three play an important role in the diagnostic process, according to speakers at a presentation on Saturday at ECR 2015.
Video from ECR 2015: Thomas Beyer, PhD, on hybrid imaging March 6, 2015 -- VIENNA - What does the future hold for PET/MRI? Can it ever be cost-effective? Thomas Beyer, PhD, a professor at the Medical University of Vienna, answers these questions in an interview with AuntMinnieEurope.com Editor-in-Chief Philip Ward at ECR 2015.
