PiB-PET shows link between arterial stiffness and beta amyloid
April 1, 2014 -- PET scans with Pittsburgh Compound B (PiB) showed a dramatic increase in brain beta-amyloid deposits in older adults with no signs of dementia, and there was also a strong association between arterial stiffness and beta amyloid, according to a study published online March 31 in the Journal of the American Medical Association.
Nuclear medicine residents see 'dismal' job market
March 27, 2014 -- The job market is not what one would call robust for would-be nuclear medicine residents, and their limitations in reading hybrid images is just one reason why, according to a new survey published in the March issue of the Journal of the American College of Radiology.
JAMA: Nuclear MPI use in Kaiser system falls dramatically
March 25, 2014 -- The use of nuclear myocardial perfusion imaging (MPI) dropped by half from 2006 to 2011 within a Kaiser Permanente healthcare system in California, but researchers can't quite point to specific reasons for the decline, according to a study published in the March 26 issue of the Journal of the American Medical Association.
CT perfusion useful for evaluating small esophageal tumors
March 19, 2014 -- CT perfusion can be used to evaluate esophageal cancers with small tumor diameters that are not amenable to assessment with PET/CT, according to a new study by Turkish researchers presented at ECR 2014 earlier this month.
NOPR: NaF-PET can change prostate cancer treatment plans
March 17, 2014 -- PET imaging with sodium fluoride (NaF) changed treatment in more than half of men with prostate cancer and could prove to be a better tool than bone scintigraphy, according to an analysis from the National Oncologic PET Registry (NOPR) published online February 27 in the Journal of Nuclear Medicine.
Florbetapir-PET links beta amyloid to cognitive decline at 3 years
March 12, 2014 -- Individuals who tested positive for beta amyloid on florbetapir-PET brain scans were more likely to decline cognitively over a three-year period than those with a negative scan, in a study published online March 11 in Molecular Psychiatry.
Nuclear medicine patient survey finds mixed results
March 12, 2014 -- Researchers from Egypt studied patient satisfaction at a nuclear medicine department and found that while the patients were satisfied with the department's infrastructure, they didn't like wait times and how they were informed of their procedures. Changes have already been made in response to the survey.
Study finds PET/CT can help diagnose CUP syndrome
March 10, 2014 -- VIENNA - FDG-PET/CT can identify a possible primary tumor in patients with carcinoma with unknown primary tumor (CUP) syndrome at a rate comparable to that found in autopsy studies, German researchers reported on Monday at ECR 2014.
Ga-68 DOTATATE PET/CT detects neuroendocrine tumor recurrence
February 21, 2014 -- German researchers have confirmed the efficacy of PET/CT with the radiopharmaceutical gallium-68 (Ga-68) DOTATATE for detecting the recurrence of neuroendocrine tumors, in a study published in the February issue of Radiology.
ACC, others call for patient-centric heart imaging
February 18, 2014 -- Noninvasive cardiovascular imaging decisions must become more patient-centric and individualized, according to a statement from the American College of Cardiology (ACC) that was endorsed by 14 other medical societies.
BSGI is effective in women of all breast densities
February 13, 2014 -- In a clinical trial inspired by the growing breast density awareness movement, researchers from Washington, DC, found that breast-specific gamma imaging (BSGI) is effective at identifying cancer in women of all breast densities, according to a paper in the February issue of the American Journal of Roentgenology.
FDG-PET/MRI shows advantages with malignant bone lesions
February 7, 2014 -- Compared to PET/CT, FDG-PET/MRI with a fully integrated whole-body scanner is "technically and clinically robust" in its evaluation of bone lesions, despite differences in attenuation correction between the two hybrid modalities, according to a study in the February issue of the Journal of Nuclear Medicine.
FDG-PET predicts risk in patients with cardiac sarcoidosis
February 6, 2014 -- In a large study of patients with known or suspected cardiac sarcoidosis, researchers found that FDG-PET could identify those at higher risk of death or life-threatening arrhythmia, according to results published in the February 4 issue of the Journal of the American College of Cardiology.
CAD uses MRI to differentiate brain tumors on FDG-PET
January 29, 2014 -- A computer-aided detection (CAD) algorithm that makes use of anatomic data from MRI scans can help radiologists differentiate between benign and malignant brain tumors on FDG-PET images, according to researchers from Yamaguchi University in Japan.
Software helps rads agree when reading florbetapir PET scans
January 27, 2014 -- PET with the radiotracer florbetapir (also known as Amyvid) is an exciting new tool that could help determine which individuals are at risk of developing Alzheimer's disease. But reading the scans can be a challenge, so Pennsylvania researchers enlisted a software application that helped boost reader agreement.
Start-up Brain Biosciences advances compact PET scanner
January 23, 2014 -- Start-up firm Brain Biosciences is hoping to ride the wave of interest in PET scanning for Alzheimer's and other brain diseases by commercializing CerePET, a portable PET scanner designed to offer more cost-effective neuroimaging than whole-body scanners.
Software adds diagnostic value for heart disease patients
January 21, 2014 -- Dutch researchers have developed 3D visualization software that fuses anatomical and functional data into a single image. They believe the fused images make it easier to diagnose cases of coronary artery disease, according to a paper in the January issue of the Journal of Nuclear Medicine.
PET with F-18 FDOPA differentiates brain lesions
January 9, 2014 -- PET with the radiopharmaceutical fluorine-18 fluorodopa (F-18 FDOPA) can help differentiate recurrent or progressive brain metastases from late or delayed radiation injury, according to a study published in the January issue of the Journal of Nuclear Medicine.
PET/MRI offers details in acute myocardial infarction cases
December 20, 2013 -- German researchers have concluded that simultaneous PET/MRI for patients with acute myocardial infarction is feasible after finding "good concordance" in a comparison of PET and MR images. The study was presented at the RSNA 2013 meeting earlier this month.
