New SPECT tracer targets NSCLC receptor
November 9, 2018 -- Researchers from the U.S. and China are developing a SPECT tracer that could improve the diagnosis and treatment of non-small cell lung cancer (NSCLC). The radiotracer targets a key receptor linked to the progression of NSCLC, according to a preclinical study published in the November issue of the Journal of Nuclear Medicine.  Discuss
Deep-learning algorithm predicts Alzheimer's disease
November 7, 2018 -- By learning to identify the metabolic patterns of Alzheimer's disease, a deep-learning algorithm for brain FDG-PET studies can accurately predict the onset of this devastating disease years before a clinical diagnosis can be made, according to new research published online in Radiology.  Discuss
Many clinicians don't follow PET/CT reporting guidelines
November 7, 2018 -- There is plenty of room for improvement when it comes to clinicians following established reporting guidelines for oncology PET/CT scans. A survey of more than 200 imaging sites worldwide found a "lack of awareness" that reporting standards even exist, according to results published online November 2 in the Journal of Nuclear Medicine.  Discuss
Robot arm assists with PET/CT-guided needle biopsies
November 6, 2018 -- By combining a robotic arm-assisted needle navigation system with PET/CT, researchers in India are performing more-accurate targeted biopsies for suspicious bone and bone marrow lesions with near-perfect diagnostic results, according to a study published online November 1 in the American Journal of Roentgenology.  Discuss
Quantitative PET better estimates amyloid plaque burden
October 18, 2018 -- Dutch researchers have developed a quantitative method of analyzing PET images acquired with the radiopharmaceutical flutemetamol that may top semiquantitative methods for identifying dementia-causing amyloid plaque, according to a study published online October 12 in the Journal of Nuclear Medicine.  Discuss
Can dedicated breast PET identify suspicious lesions?
October 9, 2018 -- A dedicated breast PET scanner fell short in a European research study assessing its value for detecting cancer in women with suspicious mammograms. Spanish researchers found the system missed nine of 18 cancers in a small group of 50 women, according to an October 3 study in the European Journal of Radiology.  Discuss
FDG-PET/CT fails for peripheral T-cell lymphoma outcomes
October 5, 2018 -- Don't expect much help from FDG-PET/CT results in predicting progression-free or overall survival among patients with peripheral T-cell lymphoma, according to a study published in the October issue of Clinical Lymphoma, Myeloma and Leukemia.  Discuss
PET/CT predicts success of rad therapy for spinal mets
October 3, 2018 -- FDG-PET/CT scans can predict the success of radiation therapy in patients with spinal metastases, especially in regard to progression-free survival, according to a study published online September 28 in PLOS One.  Discuss
PET/MRI motion correction gives readers more confidence
October 2, 2018 -- A motion correction algorithm applied to PET/MRI scans resulted in more accurate scans with fewer false positives, and readers were more confident in their interpretations, according to study results published in the September issue of the Journal of Nuclear Medicine.  Discuss
FDG-PET/CT helps stage men with breast cancer, too
September 26, 2018 -- Assessing breast cancer in men is an uncommon clinical use for FDG-PET/CT, but the hybrid modality achieves results comparable to those in women in regard to accurate staging of the disease, according to a study published online September 21 in the Journal of Nuclear Medicine.  Discuss
