1. PET/CT "a new standard" in follicular lymphoma imaging

SNMMI SmartBrief | Sep 29, 2014

An analysis of 439 scans of patients with follicular lymphoma suggests that PET/CT is the best modality for post-treatment imaging, as it predicted outcomes better than CT alone, a study in The Lancet Hematology revealed. At four years, progression-free survival in patients with a positive scan was 23%, compared with 63% for those with a negative scan. CT was "weakly predictive" of PFS, researchers wrote. (09/26)

2. Study suggests role for technologists in stress-first SPECT MPI interpretation

SNMMI SmartBrief | Sep 24, 2014

A study presented at an imaging conference found nuclear medicine technologists could read and interpret stress-first SPECT myocardial perfusion imaging scans using a standard 17-segment scoring model. Even without formal training in the approach, technologists correctly identified the need for rest imaging in 53 of 60 patients while cardiologists identified 58. Having technologists screen under a stress-first SPECT MPI protocol could improve workflow, reduce radiation dose and save money, researchers said. (free registration) (09/22)

3. Imaging suggests link between brain changes and use of media devices

SNMMI SmartBrief | Sep 25, 2014

Simultaneous use of media devices may alter the structure of brain regions tied to emotional and cognitive control, according to a study in the journal PLOS One. U.K. researchers looked at 75 adults using functional MRI, finding that those who often used multiple media devices simultaneously had lower density of gray matter in the anterior cingulate cortex compared with those who used one device infrequently.

4. FDA OKs testing of scorpion venom tumor paint

SNMMI SmartBrief | Sep 30, 2014

Blaze Bioscience has been cleared to test its scorpion venom-derived tumor dye on 21 patients with brain cancer. The compound is based on chlorotoxin found in the scorpion venom, and the substance, which binds to malignant tissue, becomes fluorescent under laser light. The company will hold the trial in the U.S. and Australia, and it expects to finish by the end of next year. KOMO-TV/KOMO-AM (Seattle) (09/27)

5. PET scans for lung cancer less effective in places where infections are common

SNMMI SmartBrief | Sep 25, 2014

A study in the Journal of the American Medical Association found that FDG-PET scans may be less effective in detecting lung cancer in geographical regions where lung infections such as fungal infections and tuberculosis are more common. Researchers found that the average specificity of FDG-PET scans in detecting lung cancer was 16% lower in regions where lung infections were prevalent. HealthDay News (09/23)

6. Region of brain larger in extremely altruistic people, study suggests

SNMMI SmartBrief | Sep 26, 2014

The brains of altruists are different from average people's brains, researchers have found. A study published in the Proceedings of the National Academy of Sciences looked at the brains of 19 healthy people who had donated a kidney to a stranger and noted that the right side of their amygdalas is 8% larger than in people who had not donated an organ to a stranger, based on data collected using fMRI.

7. New molecule shows promise for Alzheimer's disease treatment

SNMMI SmartBrief | Sep 30, 2014

A study presented at the Alzheimer's Disease Drug Discovery Foundation annual meeting suggests that an apolipoprotein J-derived compound could be used to stem the toxic effects of beta amyloid in the brain. Lab testing suggested it might protect the brain and also curb inflammation and promote functional synapses. Researchers intend to test the peptide in mice. (09/28)

8. FDA clears GE's Discovery IQ system for PET/CT

SNMMI SmartBrief | Sep 24, 2014

The FDA has granted GE Healthcare's Discovery IQ PET/CT device 510(k) clearance. The features of the new system allow for better detection of small lesions and better precision in quantitative measurements along with good image quality. (free registration) (09/23)

9. Blood test could detect pancreatic cancer earlier

SNMMI SmartBrief | Sep 30, 2014

Greater concentrations of branched-chain amino acids in the blood were associated with increased risk of developing pancreatic cancer, according to a study published in the journal Nature Medicine. Patients with higher levels of these amino acids were diagnosed with the disease after two to 25 years. Science World Report (09/29) HealthDay News (09/29)

10. Experts issue new guidelines for advanced breast cancer

SNMMI SmartBrief | Sep 24, 2014

A group of international researchers issued guidelines for the care of patients with advanced breast cancer in the journals Annals of Oncology and The Breast. The guidelines call for additional research, address imaging frequency and emphasize focusing on psychosocial needs. Medscape (free registration) (09/22)
