Specialties outside of radiology could benefit from unified databases and iPhone applications.

Cedars-Sinai Medical Center, the prestigious Los Angeles healthcare institution known as the hospital to the Hollywood stars, has been jolted by an FDA alert indicating that perfusion CT performed during an 18-month period exposed more than 200 stroke patients to eight times the normal dose of ionizing radiation for the procedures.

Swine flu patients are at risk of developing severe complications, such as pulmonary emboli, according to University of Michigan researchers. Most chest x-rays come back normal, so it’s especially important for radiologists to look closely for risks of blocked arteries in the lungs.

It should come as no surprise that the nuclear medicine community is struggling to keep up with the number of prescribed heart and bone exams. Technetium is typically used in the U.S. for more than 16 million nuclear medicine tests each year-but not this year. A survey by the SNM found that three quarters of nuclear medicine physicians are delaying patient tests, in many cases longer than a month. A shortage of medical-grade molybdenum-99 (Mo-99), the isotope critical to generating technetium, is the reason.

Coronary artery calcium scoring has been tested at the University of Western Ontario to flag nuclear myocardial perfusion scans that missed the presence of three-vessel coronary artery disease, and to triage patients who need coronary CT angiography or cardiac catheterization.

Nuclear imagers are using alternatives to keep their practices alive until the National Research Universal Reactor at Chalk River, ON, resumes production of Mo-99

A proposal to increase the assumed equipment utilization rate, combined with other payment reductions, could result in 2010 rate cuts for imaging centers greater than those imposed by the Deficit Reduction Act of 2005, a new analysis concludes.

With the goal of tailoring cancer interventions for the individual, researchers at the Lombardi Comprehensive Cancer Center at Georgetown University have published the results of a prospective study that validates the use of a simple blood test to help doctors more reliably assess treatment effectiveness for patients with metastatic breast cancer.

With the return of routine Mo-99/Tc-99 generator deliveries still at least four months away, nuclear imagers are discovering clinical alternatives from old and new diagnostic protocols to keep their practices alive.

On the eve of a major presidential speech on healthcare reform, medical imaging advocates weighed in with political broadsides urging Congress to set aside legislative proposals they say will harm imaging device sales and clinical practices.

Radiologists who believe that Washington insiders have targeted medical imaging for financial cutbacks can find plenty of evidence to raise concerns in a recent report on Medicare costs published by the Medicare Payment Advisory Committee.

A type of iterative reconstruction may reduce patient radiation dose from CT scans up to 65%, according to a study published in the September issue of the American Journal of Roentgenology.

The Canadian nuclear reactor that satisfies more than half of demand of molybdenum-99 for medical nuclear imaging services in North America will not return to service until the first quarter of 2010.

Radiologists may have to make only minor changes to their practices to adjust to the new international standards for lung cancer staging, but a lecture covering their implications was still controversial enough to send sparks flying Aug. 4 at the World Conference on Lung Cancer in San Francisco.

Blue Dog Democrats on the House Energy and Commerce subcommittee on health were credited Friday with combating liberal proposals arising during protracted deliberations that would have cut physician pay. No action was taken on an amendment that would have banned in-office imaging physician self-referral.

SNM’s Clinical Trials Network has expanded to include relationships with European PET radiopharmaceutical manufacturing sites to support molecular and nuclear imaging facilities on the continent that are gearing up to perform scientific studies for the program.

A study combining the work of two commercial health insurance plans and a Medicare Advantage managed care program indicates that imaging prior authorization dramatically slows the use of high-tech imaging in the short run, but its impact decreases over time.

The number of technologists taking primary certification exams has hit a plateau with the growth trend seen over the last eight years flattening out, according to the American Registry of Radiologic Technologists.

The window for giving tissue plasminogen activator is extended from three hours to four and a half hours after the onset of stroke under new guidelines recommended by the American Stroke Association. Results from two large multicenter trials led the group to advise expanding the time window for tPA delivery.

The nuclear reactor that serves as North America’s primary source of molybdenum-99 will not return to service before late 2009.

Experts are urging physicians to remain skeptical about controversial findings that show patients with compromised kidney function face a more than one in 10 chance of death, stroke, or myocardial infarction after experiencing contrast-induced nephropathy from coronary angiography.

Medicare reimbursement for high-tech imaging, including MRI and CT, could be cut by up to 40% if the Obama administration moves ahead with plans covered in proposed changes to the 2010 Physician Fee Schedule to shift funds to primary care physicians.

Diagnostic imaging is the focus of 11 of 100 priority research projects identified in an Institute of Medicine report released Tuesday that promises to revolutionize how the clinical efficacy and cost-effectiveness of emerging medical technologies and treatment regimens are determined in the U.S.

An article in the May 27 New England Journal of Medicine provides some interesting, and perhaps unintended, insights into the new world that is emerging as government takes a more active role in decisions about the relative value of medical procedures.

Results of a study by Italian and U.S. investigators suggest CT colonography can simultaneously spot colorectal cancer and abdominal aortic aneurysms.

Angry backers of CT colonography for colorectal cancer screening are regrouping after the Centers for Medicare and Medicaid Services repulsed their efforts to secure Medicare coverage for the procedure.
