MR targeting directs cancer-killing cells
October 2, 2015 -- Conventional cancer treatments using chemotherapy drugs can suffer from nonspecificity. New research shows MRI can direct cancer-killing cells to target sites. Not only does this technology target cancer kills, it enables anticancer agents to reach tumor sites that are normally inaccessible.
First choice for neuroendocrine tumors: Ga-68 DOTATATE
September 22, 2015 -- PET/CT imaging with radiopharmaceutical gallium-68 (Ga-68) DOTATATE significantly improves whole-body staging of patients with neuroendocrine tumors and should be the modality of choice in these cases, according to German researchers.
Neuroimaging underlines untapped potential of meditation
September 17, 2015 -- Imaging studies have confirmed that meditation can create the same physiological changes in the brain as medication for patients with clinical depression. More research needs to be done, but initial evidence suggests that, instead of medicating, people should try meditating.
PET/MRI can be a boon for pediatric cancer patients
September 11, 2015 -- Young pediatric patients may benefit from FDG-PET/MRI for staging and clinically evaluating oncologic disorders, given the hybrid modality's superior soft-tissue contrast and significantly lower radiation dose, according to a study published online August 24 in Investigative Radiology.
Lancet: Dementia imaging on cusp of a revolution
September 10, 2015 -- Imaging is on the "cusp of a revolution," according to a pan-European group of researchers who have studied the mounting evidence supporting the use of different imaging modalities in both early and established dementia. Their personal view was published online by Lancet Neurology.
PET/MRI matches PET/CT for recurrent pelvic cancer
September 8, 2015 -- PET/MRI can provide high diagnostic performance for restaging gynecological cancer patients compared with FDG-PET/CT, with only slightly longer scan time and "markedly reduced" radiation exposure, according to a German study published online in the European Journal of Radiology.
U.S. team finds favor with new PEM unit
August 7, 2015 -- A positron emission mammography (PEM) unit developed in Spain offers key advantages for breast imaging, according to a U.S. team that has been testing it. The unit offers better resolution than whole-body PET, and it may prove more useful than molecular breast imaging using technetium-99m sestamibi.
Women in medical physics: The current status
July 30, 2015 -- How well represented are women in the worldwide workforce of medical physicists? The IUPESM World Congress, held last month in Toronto incorporated five main congress themes, one of which was "Women in Biomedical Engineering and Medical Physics."
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 243.5 million euro 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.
Design changes transform potential of PET detectors
July 9, 2015 -- Two novel PET detector designs offer a significantly improved coincidence time resolution and may help better localize tumors within patients, report researchers from the Fondazione Bruno Kessler in Trento, Italy, and the Swiss-based European Organization for Nuclear Research, known as CERN.
