Sonographers exposed to radiation from MPI patients
April 17, 2018 -- A new study found that sonographers who performed cardiac ultrasound studies on patients who received nuclear myocardial perfusion imaging (MPI) scans were exposed to residual radiation from the patients. While the radiation levels were low, the researchers advised that sonographers modify their scanning techniques.  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
