PennPET Explorer acquires 1st human images
November 22, 2019 -- Researchers at the University of Pennsylvania have published the first clinical images acquired using the prototype PennPET Explorer, the second of two large axial field-of-view whole-body PET imagers developed by the U.S.-based Explorer Consortium.  Discuss
PET uncovers heightened ischemia after TBI
November 18, 2019 -- A novel PET imaging technique has uncovered high levels of ischemia in patients within the first 24 hours after a traumatic brain injury (TBI), but it also showed the condition does begin to subside over the next 10 days, according to a study published online November 11 in JAMA Neurology.  Discuss
SNMMI agrees with CMS 2020 fee schedules
November 7, 2019 -- The Society of Nuclear Medicine and Molecular Imaging (SNMMI) is breathing a collective sigh of relief after this week's release by the U.S. Centers for Medicare and Medicaid Services (CMS) of its 2020 physician and hospital outpatient reimbursement schedules.  Discuss
PET/MRI sheds light on cerebral vascular risk factors
November 4, 2019 -- PET/MRI scans show middle-aged adults with high vascular risk factors have less whole-brain volume by the time they reach their late 60s, but their lifestyle and physical characteristics do not influence beta-amyloid accumulation, according to a study published online November 4 in JAMA Neurology.  Discuss
Deep-learning model characterizes PET/CT findings
November 1, 2019 -- An artificial intelligence algorithm shows a promising level of accuracy for identifying normal and abnormal results on FDG-PET/CT exams, and it could potentially help radiologists avoid missed findings, according to research published online October 28 in the Journal of Digital Imaging.  Discuss
CEDM, MBI outperform MRI for breast cancer staging
October 31, 2019 -- Contrast-enhanced digital mammography (CEDM) and molecular breast imaging (MBI) are comparable to breast MRI when it comes to identifying breast cancer, but CEDM and MBI outperform breast MRI when it comes to treatment staging, according to a study published online October 29 in Radiology.  Discuss
Is PET really necessary to predict oncoming Alzheimer's?
October 21, 2019 -- Can a person's progression from mild cognitive impairment to Alzheimer's disease be reliably predicted without PET imaging? A new study published online October 18 in the Journal of Nuclear Medicine lists several nonimaging methods that could offer a better prognosis than the modality.  Discuss
Image processing shows potential to reduce MBI dose
October 10, 2019 -- Postprocessing software shows promise for reducing the radiation dose of molecular breast imaging (MBI) -- making way for more widespread adoption of the modality for breast cancer screening in women at higher risk or with dense breast tissue, according to a study published online October 9 in the American Journal of Roentgenology.  Discuss
Automated bone scan software proves worth with radium-223
October 10, 2019 -- An automated bone scan algorithm has shown its value in determining the response to radium-223 (Ra-223) treatment for patients with metastatic castration-resistant prostate cancer, according to a study published online October 4 in the Journal of Nuclear Medicine.  Discuss
Ga-68 PSMA-11 PET interpretation criteria need work
October 2, 2019 -- Interpretation criteria for gallium-68 (Ga-68) prostate-specific membrane antigen-11 (PSMA-11) PET with CT or MRI for prostate cancer can bolster interreader agreement, but some performance issues remain, according to a study published online September 27 in the Journal of Nuclear Medicine.  Discuss
