Novel PET agent could advance neurological imaging
April 3, 2018 -- Swiss and German researchers have obtained promising results with a novel PET imaging agent that could help guide and assess treatment for people with various neurological diseases. The preclinical study was published in the April issue of the Journal of Nuclear Medicine.  Discuss
Canada's NRU reactor to go offline for the final time
March 30, 2018 -- It's the end of an era in Chalk River, Ontario, as the National Research Universal (NRU) nuclear reactor goes offline for the final time on March 31. The reactor has been a key source of molybdenum-99, the precursor to the widely used radiopharmaceutical technetium-99m.  Discuss
NorthStar's novel generator could relieve U.S. isotope shortages
March 29, 2018 -- NorthStar Medical Radioisotopes is hoping that its isotope separation technology -- almost a decade in the making -- can alleviate worries about inadequate sources of molybdenum-99, the precursor to technetium-99m, a widely used radiopharmaceutical for nuclear medicine scans.  Discuss
ACC: PET tops SPECT for severe coronary artery disease
March 12, 2018 -- PET is significantly more proficient than SPECT in detecting severe obstructive coronary artery disease, enabling more appropriate use of revascularization treatment, according to a study presented on Saturday at the American College of Cardiology (ACC) meeting in Orlando, FL.  Discuss
ACC: PET/CT calcium scans could foretell cardiac events
March 12, 2018 -- By using PET/CT to measure the level of calcium in the coronary arteries during stress tests, clinicians can better predict which patients are at high risk of heart disease, according to a study presented on Monday at the American College of Cardiology (ACC) annual conference in Orlando, FL.  Discuss
PET/MRI falls short in lymph node metastases analysis
March 9, 2018 -- While the combination of PET and MRI has shown promise for detecting and characterizing some forms of cancer, the hybrid modality does not match the accuracy of invasive sentinel lymph node biopsy in melanoma patients, according to a study presented at ECR 2018 in Vienna.  Discuss
Video from ECR 2018: Thomas Beyer on hybrid imaging
March 3, 2018 -- VIENNA - The successful clinical implementation of hybrid imaging in Europe still appears to be a long way off. Major challenges remain, particularly in terms of training and education and also the availability of equipment. Thomas Beyer, PhD, MBA, professor of physics of medical imaging at the Medical University of Vienna, speaks about an extensive new survey that sheds light on the issues to be resolved.  Discuss
Extremity PET/CT scans unnecessary for melanoma patients
March 2, 2018 -- VIENNA - To save time and spare melanoma patients from additional radiation exposure, researchers are recommending that clinicians bypass imaging upper and lower extremities in whole-body FDG-PET/CT scans. The findings were presented on Thursday at ECR 2018.  Discuss
PET imaging shows that depression alters the brain
February 27, 2018 -- PET imaging results show that long-term depression alters the brain and suggest that different stages of the illness may need different therapies, according to a study published February 26 in Lancet Psychiatry.  Discuss
CCTA usage rate rises sharply, but still eclipsed by MPI
February 23, 2018 -- The use of coronary CT angiography (CCTA) to evaluate chest pain in the emergency department has grown exponentially, but clinicians are still using myocardial perfusion imaging (MPI) far more frequently, according to research published online February 15 in the American Journal of Roentgenology.  Discuss
