FDG-PET/CT predicts outcomes in pediatric osteosarcoma
January 19, 2018 -- The best way to predict a good outcome for pediatric patients with osteosarcoma is by performing FDG-PET/CT scans at regular intervals in the first several months after the start of chemotherapy, according to a study published in the January issue of the Journal of Nuclear Medicine.  Discuss
New PET radiotracer offers insight into multiple sclerosis
January 12, 2018 -- Combining PET scans with a novel radiotracer could help researchers track damage to myelin in the brain, providing insight into the treatment of multiple sclerosis as well as the development of other disorders, according to a preclinical study published online January 12 in Scientific Reports.  Discuss
Artificial intelligence guides lower PET tracer dose
January 11, 2018 -- In PET imaging, the amount of radiotracer dose correlates with the level of image quality. But what if artificial intelligence (AI) could enable PET to be performed using only 1% of current dose levels -- speeding exam times, decreasing radiation exposure, lowering costs, and alleviating shortages in radiotracers?  Discuss
UC Davis group reports progress on total-body PET/CT
January 5, 2018 -- Researchers at the University of California, Davis (UC Davis) report continued progress on their development of a total-body PET/CT scanner designed to image patients in less than one minute, in an article in the January issue of the Journal of Nuclear Medicine.  Discuss
Deep learning analyzes PET for signs of dementia
December 22, 2017 -- A deep-learning algorithm that analyzed FDG-PET was able to differentiate between normal cognition and dementia. Such models could someday help radiologists diagnose Alzheimer's disease, especially if they don't see the condition often, according to a study presented at the RSNA 2017 meeting.  Discuss
Florbetapir shows promise in preclinical Alzheimer's study
December 18, 2017 -- A preclinical study from Belgium has shown promising results with the PET tracer florbetapir for targeting amyloid plaque and tau tangles in the brain and potentially evaluating the efficacy of certain Alzheimer's treatments. Findings were published in the December issue of the Journal of Nuclear Medicine.  Discuss
fMRI, PET could help foresee epileptic seizure issues
December 12, 2017 -- Researchers have developed a method to integrate functional MR (fMRI) and PET images to identify epilepsy patients who are at high risk of continued seizures before the patients undergo potentially unsuccessful surgery, according to a study published online December 5 in Frontiers in Neuroscience.  Discuss
PET/MRI outclasses MRI alone for pelvic cancer recurrence
December 11, 2017 -- PET/MRI can better detect and classify local lesions and distant metastases in women suspected of having recurrent pelvic cancer than MRI alone, according to a study presented at the recent RSNA 2017 annual meeting.  Discuss
3D-printed kidney helps optimize SPECT/CT quantification
December 5, 2017 -- Low-cost, 3D-printed kidney phantoms provide shape-specific details that improve the quantification of SPECT/CT scans, according to a study from Würzburg, Germany, published online in the Journal of Nuclear Medicine.  Discuss
Philips highlights MRI, CT, and augmented radiology at RSNA
November 29, 2017 -- CHICAGO - Philips Healthcare is demonstrating a new value-oriented MRI scanner for international markets, an upgrade to its spectral CT platform, and new gamma cameras in its booth at RSNA 2017. The vendor is also giving attendees a look at the future of augmented radiology, as well as new relationships in 3D printing.  Discuss
