Study: Overuse of cardiac imaging adds to health costs
October 13, 2014 -- A new study published in Annals of Internal Medicine has concluded that the overuse of cardiac stress testing with medical imaging has contributed to rising healthcare costs.
PET/MRI matches PET/CT with less radiation for children
October 6, 2014 -- German researchers have found promising evidence that PET/MRI is equivalent to PET/CT for lesion detection in pediatric cancer patients, while at the same time delivering just one-quarter of the radiation dose, according to a study published in the October issue of Radiology.
SNMMI: Mo-99 supply issues still shape nuclear medicine
October 3, 2014 -- The tenuous supply of molybdenum-99 (Mo-99) in recent years has resulted in a double-digit price increase at many nuclear medicine facilities across the U.S., as well as the canceling or rescheduling of appointments and fewer after-hours exams.
Use of SPECT MPI exercise stress continues to decline
September 30, 2014 -- The convenience of pharmacologic stress agents and an increase in patient mobility issues are contributing to a decades-long decline in the use of exercise stress for SPECT myocardial perfusion imaging (MPI), according to a study presented at the American Society of Nuclear Cardiology annual meeting.
JAMA: PET falls short in areas with widespread lung disease
September 25, 2014 -- A new study in the September 24 issue of the Journal of the American Medical Association found that FDG-PET has sharply lower specificity for diagnosing lung cancer in geographic regions where infectious lung disease is common. The findings could affect how PET is used for following up CT lung screening studies.
ASNC: Should nuclear technologists read SPECT MPI scans?
September 22, 2014 -- BOSTON - Nuclear medicine technologists were nearly as accurate as cardiologists in reading stress-first SPECT myocardial perfusion imaging (MPI) studies, according to research presented at the American Society of Nuclear Cardiology (ASNC) meeting. The study hints at a role for technologists in determining which patients could avoid the rest portion of the scans.
FDG-PET/CT benefits breast cancer patients younger than 40
September 17, 2014 -- While guidelines recommend FDG-PET/CT only as an optional workup for women with stage III breast cancer, the hybrid modality can help women younger than 40 who have potentially aggressive stage II breast cancer, according to a study published online September 11 in the Journal of Nuclear Medicine.
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.
