PET agent highlights tau's link to Alzheimer's disease
May 12, 2016 -- With the help of a new PET imaging agent, researchers at Washington University in St. Louis have shown how tau protein deposits in the brain are better indicators of a person's likely progression to Alzheimer's disease than beta amyloid, according to a study published May 11 in Science Translational Medicine.
Cardiac MRI beats SPECT for predicting heart events
May 10, 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.
Inappropriate MPI scans increase cancer risk among women
May 6, 2016 -- The inappropriate use of SPECT myocardial perfusion imaging (MPI) in women can increase their risk of cancer from radiation compared to men, according to a study published online April 21 in the Journal of Nuclear Medicine.
Inappropriate SPECT MPI scans more common in women
April 28, 2016 -- Women are more likely than men to have an inappropriate SPECT myocardial perfusion imaging (MPI) scan, partly due to atypical symptoms, which may overestimate the true health risk to the female patient.
SPECT finds low cerebral blood flow in NFL players
April 26, 2016 -- SPECT imaging shows abnormally low blood flow in the brains of current and retired National Football League (NFL) players, according to a new study to be published in the Journal of Alzheimer's Disease.
Cardiac PET/MRI protocol reduces radiation dose
April 21, 2016 -- Researchers have developed a new cardiac PET/MRI protocol with sodium fluoride that significantly reduces radiation dose and artifacts, enhancing the view of disease activity in coronary arteries.
PET obviates toxic chemo for some Hodgkin's patients
April 12, 2016 -- By using FDG-PET to guide chemotherapy, oncologists can significantly increase the number of patients who go into remission and decrease the use of more toxic forms of chemotherapy in those with advanced Hodgkin's lymphoma, according to a study published online April 11 in the Journal of Clinical Oncology.
Radiopharma dose varies globally for pediatric exams
April 7, 2016 -- While there are guidelines for recommended radiopharmaceutical doses for pediatric nuclear medicine patients, there is still wide variability around the world in terms of how those standards are followed, according to a new report published online March 31 in the Journal of Nuclear Medicine.
Study: No big gender differences in nuclear MPI dose
April 5, 2016 -- Despite some geographic variability, there are no major differences in the way nuclear myocardial perfusion imaging (MPI) studies are performed on men and women around the world, including the amount of radiation delivered, according to a new study published in JACC: Cardiovascular Imaging.
PET/CT after therapy avoids surgery for head, neck cancer
March 24, 2016 -- Using PET/CT scans to assess response to therapy can help patients with head and neck cancer avoid invasive post-treatment surgery to remove any remaining cancer cells, according to a U.K. study published online March 23 in the New England Journal of Medicine.
