NIH to fund PET imaging for Latino Alzheimer's study
September 14, 2020 -- The U.S. National Institutes of Health (NIH) has provided additional funding for researchers to use PET imaging to study Alzheimer's disease among Mexican Americans. The funds add amyloid and tau PET imaging to the ongoing Health and Aging Brain Among Latino Elders study.  Discuss
FET-PET offers more info on treatment of brain metastases
September 14, 2020 -- Using PET with the radiolabeled amino acid F-18 fluoroethyl tyrosine (F-18 FET) can significantly help determine the efficacy of radiotherapy in certain cancer patients who develop brain metastases, according to a study published online September 4 in the Journal of Nuclear Medicine.  Discuss
PET radiomics tailor head/neck cancer treatment
September 10, 2020 -- Radiomic factors -- that is, image-based tumor phenotypes -- gleaned from F-18 FDG PET exams can help clinicians personalize care and better predict treatment outcomes for patients with head and neck squamous cell carcinoma, according to a study published September 7 in EJNMMI Research.  Discuss
Nuclear medicine volume plummets due to COVID-19
September 8, 2020 -- It's no secret COVID-19 has disrupted nuclear medicine clinical practice, research, and work environments. However, a new survey by the Society of Nuclear Medicine and Molecular Imaging quantifies the effects: nearly 80% of respondents saw declines of 50% to 75% in non-PET nuclear medicine procedures.  Discuss
SNMMI updates ventilation study guidance
September 8, 2020 -- The Society of Nuclear Medicine and Molecular Imaging (SNMMI) has updated its statement regarding the use of ventilation/perfusion lung studies during the COVID-19 pandemic to recognize that sometimes these studies are clinically necessary.  Discuss
Dual-phase technique improves PET/CT brain tumor imaging
September 3, 2020 -- Using a dual-phase technique with F-18 FDG PET/CT -- that is, performing the exam at two time points after FDG administration -- improves the modality's lesion detection and diagnostic accuracy in malignant brain tumors, according to a study published August 25 in the American Journal of Roentgenology.  Discuss
PET/CT could be useful for diagnosing fever
August 27, 2020 -- F-18 FDG PET/CT could be an effective tool for evaluating unexplained fevers -- and thus improving how quickly patients can be diagnosed, according to a study published online August 23 in Clinical Infectious Diseases.  Discuss
PET/MRI ups lesion detection by 15% for some cancers
August 26, 2020 -- In a study of more than 1,000 exams, PET/MRI improved lesion detection by more than 15% compared with PET/CT in selected cancers -- namely malignant bone disease and lung cancer. In addition, PET/MRI reduced ionizing radiation by nearly 80% when compared with PET/CT.  Discuss
Follow-up SPECT/CT scan tracks radionuclide dose
August 13, 2020 -- Australian researchers have developed a technique that uses a follow-up SPECT/CT scan after radionuclide therapy to personalize the radiation dose delivered, according to a study published in the July issue of the Journal of Nuclear Medicine.  Discuss
New radiotracer increases multiple myeloma survival
August 11, 2020 -- A new alpha-radioimmunotherapy agent, Pb-212-anti-CD38, prevented tumor growth and increased survival in multiple myeloma tumor-bearing mice, according to new research published in the Journal of Nuclear Medicine.  Discuss
