Study adds evidence linking Alzheimer's to sleep disorders August 1, 2014 -- PET images with the radiopharmaceuticals FDG and Pittsburgh Compound B have shown a connection between sleep disorders such as sleep apnea and preclinical Alzheimer's among the cognitively normal elderly, according to researchers in New York City.

AAPM: Radiomics helps fine-tune radiation therapy dose July 24, 2014 -- By extracting statistical information and other measurements from PET images using a data analysis technique called radiomics, researchers have developed a way to determine radiation therapy dose more accurately, according to a study presented this week at the American Association of Physicists in Medicine (AAPM) meeting.
PET agents differentiate Alzheimer's, cardiovascular disease July 17, 2014 -- Researchers have found that using PET brain imaging with florbetapir and FDG can differentiate cardiovascular disease from symptoms of mild cognitive impairment or Alzheimer's disease. The combination can also detect amyloid plaques in patients with cardiovascular disease.
Moments in Radiology History: Part 16 -- Early nuclear medicine July 11, 2014 -- After early efforts began to harness the power of x-rays for diagnosis and therapy, some physicians and physicists chose to focus instead on the development of radioactive isotopes. In his latest Moments in Radiology History installment, radiology historian Otha Linton examines the advances that ultimately led to the field of nuclear medicine.
Early trial of PET tracer shows promise for brain tumors July 2, 2014 -- Researchers at the University of Wisconsin's UW Health system have completed the first successful human clinical trial of a new PET radiopharmaceutical that targets and detects brain tumors more specifically than FDG.
4-scan PET/MRI exams improve breast imaging June 25, 2014 -- Austrian researchers added PET/CT to a package of three MRI sequences to create fused PET/MR images, which they found aided in the differentiation of suspicious breast lesions, according to a new study published online in Clinical Cancer Research.
Dementia link? SPECT finds brain changes in football players June 19, 2014 -- SPECT imaging has uncovered abnormal cerebral blood flow in retired professional football players in brain regions associated with frontotemporal dementia and Alzheimer's disease, according to a poster presentation at last week's Society of Nuclear Medicine and Molecular Imaging (SNMMI) meeting.
SNMMI: PET, MRI may predict pediatric brain tumor outcomes June 11, 2014 -- ST. LOUIS - Researchers from Boston Children's Hospital have found that certain PET and MR imaging characteristics of brain tumors in pediatric patients may help predict progression-free and overall survival, according to a study presented on Tuesday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) meeting.
SNMMI: ARMI trial shows benefits of Rb-82 PET for heart disease June 10, 2014 -- ST. LOUIS - Trial results presented on Monday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) meeting show that rubidium-82 PET outperformed thallium-201 SPECT for diagnosing obstructive coronary artery disease -- all while exposing patients to less radiation.
