PET/CT tumor volume best predicts breast cancer survival July 30, 2015 -- Whole-body metabolic tumor volume, as determined by FDG-PET/CT before treatment, is a reliable prognosticator of overall survival in patients who have invasive ductal carcinoma of the breast and distant metastases at the time of their initial diagnosis, according to a study published online July 23 in the American Journal of Roentgenology.
Guerbet bids to buy Mallinckrodt's contrast business July 27, 2015 -- French contrast agent developer Guerbet plans to acquire the contrast media and injector business of U.S. firm Mallinckrodt. The $270 million deal will double Guerbet's annual revenues, expand its product line, and instantly make the company a major player in the U.S. contrast market.
SPECT distinguishes TBI, PTSD in broad population July 20, 2015 -- SPECT is once again showing its value by distinguishing the fine line between post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) in nonmilitary patients, which should lead to better treatment for the disorders.
Brain SPECT shows improvement after cocaine users abstain July 10, 2015 -- Dysfunction in the prefrontal cortex region of the brain caused by excessive cocaine use may be reversed to some degree after more than one month of abstinence, researchers from Uruguay have found. Their findings are promising news for rehabilitation efforts, but the group cautioned that some brain dysfunction does appear to remain.
Proposal would dissolve ABNM, fold functions into ABR June 25, 2015 -- In the face of an increasingly difficult job market for nuclear medicine physicians, a proposal has been floated to dissolve the American Board of Nuclear Medicine (ABNM) and fold its functions into the American Board of Radiology (ABR). The combined organization would oversee a new, broader certification for imaging specialists.
Florbetaben-PET finds more beta-amyloid plaques June 22, 2015 -- New research indicates that PET imaging with the radiotracer florbetaben can detect a form of beta-amyloid plaque that develops early in the brain. The findings could possibly lead to the earlier detection of Alzheimer's disease, as well as new clinical indications for florbetaben.
OCT tool offers fast intraoperative brain tumor imaging June 19, 2015 -- A new brain tumor imaging technique based on optical coherence tomography (OTC) may offers surgeons a highly accurate way to visualize -- and ultimately resect -- malignant tumors during surgery, according to a report from Johns Hopkins University.
Annals: Few differences in CCTA vs. SPECT MPI June 11, 2015 -- A study comparing coronary CT angiography (CCTA) with SPECT myocardial perfusion imaging (MPI) in chest pain patients found that CT's radiation dose was lower and that it yielded fewer unpleasant experiences among patients, according to results published in the Annals of Internal Medicine.
SNMMI: FDG-PET/CT predicts ovarian cancer survival June 10, 2015 -- BALTIMORE - FDG-PET/CT scans can help predict disease progression and overall survival of ovarian cancer patients for as long as several years after treatment, according to a Tuesday presentation at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting.
SNMMI: FDOPA-PET/MRI monitors pediatric brain tumors June 9, 2015 -- BALTIMORE - Clinicians may soon be able to add PET/MRI with F-18 fluorodopa (FDOPA) to their imaging arsenal to evaluate the efficacy of the angiogenesis inhibitor bevacizumab for pediatric brain tumors, according to a study presented on Monday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting.
