NIH navigates 'perfect storm' in 2006
November 16, 2006 -- CHICAGO - The events of 2006 have left the National Institutes of Health (NIH) with little to cheer about, according to its director Dr. Elias Zerhouni. But the agency is gearing up for an expanded presence and more medical breakthroughs in the years ahead. At the American Heart Association (AHA) meeting on Tuesday, Zerhouni discussed how the current shortfalls for funding research aren't about a lack of money, but have more to do with increased competition for grants.  Discuss
Dual-source CT overcomes artifacts in coronary imaging
November 14, 2006 -- CHICAGO - Dual-source CT (DSCT) is the best option for the detection of coronary artery stenosis and the elimination of artifacts created by a patient's heart rate, according to two studies presented on Monday at the 2006 American Heart Association (AHA) meeting.  Discuss
Investment firm garners third ultrasound THI patent, approaches vendors about licensing
October 10, 2006 -- A Tucson, AZ, patent management firm has received its third U.S. patent for tissue harmonic imaging (THI), a widely used technology found on many ultrasound scanners. While the company is not detailing its specific plans for defending the patents, it has already licensed the technology to one ultrasound vendor and says it is approaching others about similar deals.  Discuss
PET helps uncover dopamine's influence on alcoholism

Timing is everything in contrast-enhanced CT
September 28, 2006 -- When imaging the abdominal aorta and the lower extremity arterial tree in patients with peripheral arterial occlusion disease (PAOD), matching the contrast injection to when CT scanning begins in those regions is key. Researchers at Stanford University have developed protocols for optimal wait times between contrast injection and the start of CT imaging based on the time it takes the bolus to reach the abdominal aorta or arterial tree.  Discuss
Antiscatter grids may not be helpful in some DR applications
September 22, 2006 -- In the quest for an optimum balance between image quality and radiation dose in digital radiography (DR), a U.K. group looked at whether better DR image quality provided through the use of an antiscatter grid justified an increase in effective dose to patients.  Discuss
Study: Premature wear can cause CR image artifacts
September 21, 2006 -- In a study of more than 250 computed radiography (CR) systems from three vendors, a group of researchers from Vancouver General Hospital in British Columbia have found that premature wear of cassettes and image plates can cause image artifacts.  Discuss
Student-designed CT-guided biopsy device shows early promise
