ASTRO: Imaging, radiation oncology increasingly work as one
September 16, 2014 -- SAN FRANCISCO - Imaging is central to the unprecedented wave of medical specialties converging on cancer care. But it will take more than what today's radiologists are trained for to better understand cancer's mysteries, according to a keynote address by Dr. Hedvig Hricak, PhD, on Monday at the American Society for Radiation Oncology (ASTRO) meeting.

ASCO BCS research highlights benefits of mobile mammo, PET/MR
September 15, 2014 -- Screening for breast cancer with mammography isn't perfect -- and neither are the modalities used to track women already diagnosed with the disease. At the recent American Society of Clinical Oncology (ASCO) Breast Cancer Symposium (BCS) in San Francisco, researchers discussed ways to find and track breast cancer more effectively.
Lawsuit attacks CMS policy on PET beta-amyloid scans
September 11, 2014 -- Three women have filed suit against the U.S. Centers for Medicare and Medicare Services (CMS), seeking to invalidate the agency's reimbursement policy for PET beta-amyloid scans to detect early signs of Alzheimer's disease. The litigation charges that CMS overstepped its authority when it implemented the policy last year.
Ultralow-dose SPECT provides top image quality, less radiation
August 29, 2014 -- With an eye toward lowering radiation exposure, a group of researchers found that an ultralow-dose high-efficiency SPECT scan for myocardial perfusion imaging can achieve better image quality than standard low-dose SPECT, according to a study published in the September Journal of Nuclear Medicine.
Researchers dial back FDG activity to reduce PET/MRI dose
August 21, 2014 -- European researchers have set the groundwork for what they believe is a feasible way to achieve optimal image quality in PET/MRI scans: balancing lower radiotracer dose with prolonged PET image acquisition time to match the longer duration needed for MR image acquisition.
Circulation: Little radiation risk seen in cardiac scans
August 11, 2014 -- A lack of demonstrated harms combined with significant recent dose reductions have led at least one group of cardiovascular imaging specialists to worry less about the risks of a heart scan and more about the well-being of the patient, according to a new review article in Circulation.
Pilot study shows PET/MRI's benefits for large-vessel vasculitis
August 7, 2014 -- Evidence supporting the clinical value of PET/MRI continues to mount, as a small study from Germany has found that the hybrid modality is effective for evaluating patients with large-vessel vasculitis.
Study adds evidence linking Alzheimer's to sleep disorders
August 1, 2014 -- PET images with the radiopharmaceuticals FDG and Pittsburgh Compound B have shown a connection between sleep disorders such as sleep apnea and preclinical Alzheimer's among the cognitively normal elderly, according to researchers in New York City.
AAPM: Radiomics helps fine-tune radiation therapy dose
July 24, 2014 -- By extracting statistical information and other measurements from PET images using a data analysis technique called radiomics, researchers have developed a way to determine radiation therapy dose more accurately, according to a study presented this week at the American Association of Physicists in Medicine (AAPM) meeting.
PET agents differentiate Alzheimer's, cardiovascular disease
July 17, 2014 -- Researchers have found that using PET brain imaging with florbetapir and FDG can differentiate cardiovascular disease from symptoms of mild cognitive impairment or Alzheimer's disease. The combination can also detect amyloid plaques in patients with cardiovascular disease.
