ATLANTA--In choosing the appropriate test, keeping clinical context in mind and understanding what the test indicates and what it does not indicate are key elements a physician must remember in selecting the correct imaging modality for the testing of myocardial viability, said Christopher Hanson, MD, professor of medicine and radiology at Thomas Jefferson University Hospital in Philadelphia, during an imaging symposium at the American College of Cardiology (ACC) annual conference on Monday.
ATLANTA -- The presence of obstructive coronary artery disease (CAD) was found to be a significant predictor of adverse cardiac events, and multi-detector CT may be able to predict cardiac events in known or suspected CAD, according to researchers from the Division of Cardiology at Daegu Catholic University in Daegu, South Korea.

Rcadia Medical Imaging has been issued a CE Mark for its computer-aided detection software--the COR Analyzer system--that helps identify patients with significant coronary artery disease by an analysis of coronary CT angiography (CCTA) studies.
Medical software provider Medipattern has signed a 38-site agreement with Doshi Diagnostic Imaging Services of New York and Florida to install its B-CAD-For-Life package, its breast care program.
iCAD has reported steady profits for the fourth quarter of fiscal year 2009, but it wasn’t enough to put the company into the black for the year, which ended Dec. 31.
In a trial to assess gender differences in coronary plaque composition, researchers found that women presented less coronary segments with calcified and mixed plaque than men and had exhibited lower rates of coronary segments with stenosis equal to or fewer than 70 percent. The study was published in the Feb. 15 issue of the American Journal of Cardiology.
The European PACS market will grow by about 5.9 percent annually through 2015, according to a report published by GlobalData, a market research firm.
Linear polyp measurement in the 3D endoluminal view appears to be the most reliable parameter for use in the decision to excise a polyp by the linear metric approach and manual volume is the most reliable measurement parameter for observing polyp growth over time, according to a study published in the December issue of the American Journal of Roentgenology.
Medical software developer Medipattern and Sentinelle Medical, a manufacturer of MRI coils and advanced visualization software, are entering a technology access and distribution agreement.
Computer-assisted detection developer Riverain Medical has formed a partnership with Canadian medical imaging distributor, Christie Group.

ATLANTA--“Within the past decade, our focus on women at risk has led to a clarification of understanding of the sex-specific factors that can influence our decisions and testing when it comes to women at risk or with symptoms of heart disease,” said Jennifer Mieres, MD, associate professor of medicine and director of nuclear cardiology at New York University School of Medicine, during a presentation at the 59th annual American College of Cardiology (ACC) conference.
A coronary CT angiography-only approach -- when factoring in a $20,000 threshold level for cost per correct diagnosis and $50,000 per quality-adjusted life-year -- is the most cost-effective diagnostic strategy for the evaluation of patients presenting with stable chest pain without known coronary artery disease (CAD) with intermediate CAD prevalence, according to a decision analysis study published in the March issue of Radiology.
Image analysis and workflow solutions provider iCAD has been granted a patent-number 7,660,448, which will cover all future iterations of its SecondLook Digital computer-aided detection (CAD).

With the plethora of clinical data emerging at this month’s American College of Cardiology annual meeting, the sessions are seeking to provide clinicians and administrators with methods to improve the quality of evidence-based care.
While coronary CT angiography (CCTA) can assist in the diagnosis of coronary artery disease (CAD), the radiation dose exposure during an exam has been a problem. Using volume scans rather than helical scans has the potential to reduce dose by 91 percent, a study published in the March issue of Radiology found.
The absence of coronary calcification does not exclude obstructive stenosis or the need for revascularizations in patients suspected to have coronary artery disease (CAD), based on results of a substudy of the CORE 64 registry data published in the Feb. 16 issue of the Journal of the American College of Cardiology.
While radiologists are ready and willing to take advantage of the benefits provided by advances in medical technology, without adequate training and an understanding of what that technology can do, it loses much of its utility.
Large irregular polyps, despite being correctly marked by computer-aided detection (CAD) software, are often ignored by reporting radiologists during CT colonography. A group of researchers from University College Hospital in London, writing in the December issue of Radiology, endeavored to find out why.

CHICAGO--There are many factors that can lead to a radiologist missing a cancer diagnosis during mammography screening; however, there are tools and methods currently in place that may reduce the occurrence of misdiagnosis, said Robyn Birdwell, MD, during the Computer-Aided Detection (CAD) in Practice: Hope and Hype session at the Radiological Society of North America (RSNA) annual conference on Tuesday.
The Centers for Medicaid & Medicare Services (CMS) will increase the reimbursement for PET myocardial perfusion imaging (MPI) by 24 percent in the Hospital Outpatient Prospective Payment System, which will go into effect Jan. 1, 2010.

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.
