PET tracks Zika virus, disease progression in mice
September 21, 2017 -- Researchers from the U.S. Army are using PET scans of mice to study brain inflammation and gather more information about the progression of disease due to the Zika virus, according to a study published online September 12 in Molecular Imaging and Biology.  Discuss
FDG-PET/CT contributes to anal cancer follow-up
September 13, 2017 -- Given its high sensitivity and negative predictive value, French researchers are promoting FDG-PET/CT for its ability to assess response to treatment and redirect therapy for patients with recurrent or progressive anal cancer, in a study published in the September issue of the Journal of Nuclear Medicine.  Discuss
AI algorithm can classify bone lesions on PET/CT images
September 7, 2017 -- An artificial intelligence (AI) algorithm can reliably classify benign and malignant bone lesions on F-18 sodium fluoride PET/CT images, showing promise for automating a time-consuming and subjective process for nuclear medicine physicians, according to a research team from the University of Wisconsin in Madison.  Discuss
Shorter PET/MRI scans feasible for pediatric cancer patients
August 23, 2017 -- Researchers at Stanford University have developed a single-session PET/MR imaging protocol that reduces scan times for cancer patients and increases accuracy for evaluating chemotherapy-induced brain, heart, and bone abnormalities, according to a study published online August 4 in Radiology.  Discuss
AI predicts dementia years before symptoms occur
August 22, 2017 -- An artificial intelligence (AI) algorithm can recognize the signatures of dementia on amyloid PET scans two years before the onset of symptoms, according to research published online recently in Neurobiology of Aging.  Discuss
Hybrid modalities disappoint in bone metastases accuracy
August 21, 2017 -- Despite the apparent technological advantages of SPECT/CT, PET/CT, and PET/MRI, the three hybrid modalities do not perform appreciably better than planar bone scintigraphy in detecting and diagnosing bone metastases, according to a study published online August 10 in the Journal of Nuclear Medicine.  Discuss
JAMA: PET best option to diagnose ischemic heart disease
August 17, 2017 -- A head-to-head comparison to determine the most accurate modality for diagnosing myocardial ischemia has found that PET outperforms SPECT, coronary CT angiography, and hybrid variations of the three modalities in patients with suspected coronary artery disease, according to a study published online August 16 in JAMA Cardiology.  Discuss
PET links low serotonin levels to dementia
August 15, 2017 -- PET brain scans of people with mild cognitive problems show evidence of lower serotonin transporter levels, which can be an early indication of Alzheimer's disease or other dementias, according to a study published in the September issue of Neurobiology of Disease.  Discuss
Novel near-infrared agent could benefit lung nodule surgery
August 10, 2017 -- Researchers at the University of Pennsylvania are advancing lung cancer surgery by combining intraoperative molecular imaging with a novel near-infrared contrast agent and preoperative PET/CT scans to help surgeons better see and extract both obvious and hard-to-find tumors.  Discuss
New PET tracer could work well for prostate cancer
August 7, 2017 -- A new PET radiopharmaceutical based on carbon-11-labeled sarcosine could offer an alternative to choline-11-based PET for imaging patients with prostate cancer, according to a study published in the Journal of Nuclear Medicine.  Discuss
