An international study on CT perfusion imaging at 15 medical centers in eight countries, led by researchers at Johns Hopkins University in Baltimore, have enrolled the first dozen patients to figure out how well various imaging tests can measure the degree of blockage or narrowing in any particular artery and their use in predicting patients who need catheterization or angioplasty, or bypass surgery.
Researchers at Massachusetts Institute of Technology and Harvard Medical School have built targeted nanoparticles that can cling to artery walls and slowly release medicine, which could be an alternative to drug-eluting stents in some patients with cardiovascular disease, according to research published in the Jan. 18 issue of the Proceedings of the National Academy of Sciences.
ContextVision has made its GOPView iRV Plus available on a field-programmable gate array (FPGA) platform.
The Society of Interventional Radiology (SIR), which has previously published clinical practice guidelines on radiation dose management, has released a new document providing guidance on the safe use of fluoroscopy on pediatric and adult patients.
Treating critical limb ischemia in peripheral arterial disease (PAD) patients with below-the-knee angioplasty is thwarted by restenosis, the need for repeat treatments and the continued progression of atherosclerotic disease, leading to tissue death and amputation. However, interventional radiologists have found that drug-eluting stents (DES) lessen the rate of repeat procedures to open these small arteries, according to results presented at the Society of Interventional Radiology (SIR) annual meeting in San Diego this week.
Medtronic reported strong growth in profits for the medical device manufacturer's fiscal 2009 third quarter, which ended Jan. 23.
WASHINGTON—After one year, use of a drug-eluting stent (DES) in heart attack patients demonstrated significantly reduced rates of target lesion revascularization and binary angiographic restenosis when compared to the use of a bare metal stent (BMS), according to the HORIZONS AMI trial presented Wednesday at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium.

Medical imaging provider NovaRay Medical and business research and development group Triple Ring Technologies have developed an x-ray imaging system utilizing processing technology from Nethra Imaging, a Santa Clara, Calif.-based diagnostic imaging company.
The Leapfrog Hospital Survey, which annually compares hospital performance on standards of safety, quality and efficiency, added 45 hospitals to the highest ranking of quality care this year.
Primary PCI and a policy of pre-hospital lysis followed by transfer to an interventional center have similar mortality rates at five years, which is consistent with the 30-day outcomes, according to the CAPTIM trial in the July issue of the European Heart Journal.
Interventional radiologists are establishing how to use stem cells to create new or more blood vessels to treat peripheral arterial disease (PAD) in individuals with extensively narrowed or clogged arteries. Recent successful techniques use imaging to view and locate transplanted stem cells, and to confirm that they remain alive in the body once injected, according to a study presented at the Society of Interventional Radiology (SIR) annual conference this week in San Diego.
Interventional radiology treatments are making childbirth safer for women who have C-sections that are complicated by massive bleeding and for those who suffer from the pregnancy condition of "invasive" placenta, according to two studies released at the annual meeting of the Society of Interventional Radiology (SIR) this week in San Diego.
Researchers have found that Medicare recipients who undergo elective percutaneous coronary intervention (PCI) often do not get the recommended stress tests to confirm the surgery is warranted, according to a study published in the Oct. 15 issue of the Journal of the American Medical Association.

The use of health IT to reduce rehospitalizations will be welcome but also disruptive, said Stephen Jencks, an independent consultant in healthcare safety during a Feb. 24 webinar on the potential use of health IT to mitigate rehospitalizations, sponsored by the Agency for Healthcare Research and Quality (AHRQ).
During the Health IT Standards Committee meeting on Feb. 24 in Washington, D.C., the Clinical Operations Workgroup sought to gather comments on proposed recommendations on implementation specifications for content exchange, vocabulary and code set standards for the Interim Final Rule of meaningful use.
In 2006, the Center for Devices and Radiological Health (CDRH), a branch of the FDA, began examining the number of medical device reports they received. Over the past two years, the number of submitted reports has increased, sparking a demand for the CDRH to make a move to electronic reporting.
A new hospital breaking ground usually isn’t breaking news. But the vision of patient care at one new facility, tentatively named Palomar Medical Center West (PMC West), is currently illegal under California state law.
