CZT-based SPECT MPI may predict cardiac outcomes
May 9, 2017 -- SPECT gamma cameras featuring cadmium zinc telluride-based (CZT) digital detector technology are just what the nuclear cardiologist ordered to diagnose seemingly healthy patients with cardiac symptoms and to help predict their chances for an adverse event, according to a study published online April 27 in the Journal of Nuclear Medicine.
Nuclear cardiology lab cuts radiation dose by 60%
May 8, 2017 -- A large nuclear cardiology lab was able to reduce its average radiation dose by 60% over the past eight years, according to new research presented on Friday at the International Conference on Nuclear Cardiology and Cardiac CT in Vienna and published in JACC: Cardiovascular Imaging.
SPECT/CT can solve renal cell carcinoma diagnosis conundrum
April 27, 2017 -- By turning to a SPECT/CT scan with technetium-99m sestamibi, clinicians can overcome inconclusive or suspicious CT or MRI results and are better able to characterize and diagnose renal cell carcinoma, according to a study published in the April issue of Clinical Nuclear Medicine.
PET plays key role in preventive Alzheimer's study
April 19, 2017 -- With projections that the number of people living with Alzheimer's disease in the U.S. could more than triple by the year 2050, 65 research institutions are collaborating on a clinical trial using PET scans to identify the disease in its earliest stages, as well as guide the use of potential therapeutic agents.
PET links midlife vascular risk factors to more amyloid
April 11, 2017 -- Florbetapir-PET scans show that midlife adults with two or more vascular risk factors are significantly more likely to have greater levels of amyloid deposits in their brains later in life than peers with no such risk factors, according to a study published April 11 in the Journal of the American Medical Association.
IBA Molecular forms Curium as new radiopharmacy player
April 6, 2017 -- Radiopharmacy vendor IBA Molecular has combined with recent acquisition Mallinckrodt Nuclear Medicine to form Curium, a new company with a mission to be a global developer, manufacturer, and supplier of SPECT, PET, and therapeutic radiopharmaceuticals.
Reduced FDG dose levels for PET/MRI show mixed results
April 6, 2017 -- Even though a lower dose of FDG did not significantly affect lesion detection for most adult cancer patients undergoing a whole-body PET/MRI scan, German researchers recommend that clinicians stay with recommended levels to avoid artifacts, according to a study published in the Journal of Nuclear Medicine.
Role of imaging modalities is changing for PE diagnosis
March 31, 2017 -- The use of ventilation/perfusion SPECT scans to rule out pulmonary embolism (PE) is evolving. What used to be the definitive test for PE is shifting into a role that harmonizes with the use of pulmonary CT angiography, according to an article in the American Journal of Roentgenology.
FDG-PET/CT can direct biopsies for pediatric cancer
March 8, 2017 -- FDG-PET/CT can play a valuable role in directing image-guided biopsies of pediatric cancer patients, given its ability to detect and discern between malignant and benign regions, according to a study by a group from Saudi Arabia and Canada published in the March issue of the American Journal of Roentgenology.
Novel PET tracer aids recurrent prostate cancer patients
March 8, 2017 -- A study in the March issue of the Journal of Nuclear Medicine is touting the PET radiotracer fluciclovine F-18 for its ability to guide and monitor targeted treatment for recurrent prostate cancer.
