Agfa debuts small-footprint, high-performance CR reader
December 9th 2009Agfa Healthcare extended its computed radiography portfolio with the global launch at RSNA 2009 of a compact, high-volume reader. Agfa also raised expectations among customers in the market for digital radiography systems with the unveiling of two works-in-progress built around flat-panel detectors.
Repeat/reject analysis makes case for digital training
It’s been argued that repeat/reject analysis, a quality-assurance tool to observe trends and make improvements that help reduce the need for repeat images, is not necessary when using digital equipment. While it is true that digital imaging reduces some error rates, the results on the Mayo Clinic digital poster exhibit at the RSNA meeting showed that mistakes still occur in the digital environment.
Digital mammography vendors switch into low gear
December 8th 2009New offerings shown at RSNA 2009 by the makers of digital mammography equipment reflected a new reality in the U.S. market, one based on cost constraints and diminishing demand. Vendors emphasized low-cost solutions that guard against obsolescence at the expense of premium ones, a change spurred by the continuing recession in the U.S. and an installed base increasingly saturated with high-end full-field digital mammography systems.
IR urges moratorium of vertebral compression fracture interventions
Interventional radiologists should refrain from performing either kyphoplasty or vertebroplasty unless the procedure, intended mostly for the management of pain from vertebral compression fractures, is done in the context of clinical trials.
Multigland parathyroidism reduces accuracy of lesion detection
Standard nuclear scintigraphy of parathyroid cancer produces enough false positives for patients with multigland disease to lead researchers to recommend rapid intraoperative parathyroid hormone assay along with preoperative technetium-99m sestamibi imaging to assure that all lesions have been removed.
Bone marrow lesions, female sex, predict knee osteoarthritis progression
Knee osteoarthritis progression can be predicted by MRI findings of medial collateral ligament edema, bone marrow lesions, and being female, according to a study presented at the RSNA meeting Thursday morning.
Toshiba unveils wide-bore 3T MR scanner
December 4th 2009Toshiba laid the groundwork for entering the 3T marketplace in the U.S. with the unveiling of its Vantage Titan 3T system at RSNA 2009. The work-in-progress, which is pending FDA clearance, leapfrogs earlier generations of 3T scanners with a 71-cm tapered aperture and Pianissimo noise reduction technology.
Advanced MRI reveals damage in brains of retired NFL football players
The brains of 16 retired National Football League players with known cognitive impairment show signs of damaging atrophy, according to advanced MRI studies described Wednesday at the 2009 RSNA annual meeting.
Technology, physiology streamline cardiac CTA contrast dose
Increasing CT scanning speeds and image resolution combined with automated injection and optimized protocols tailored to specific patient features could reduce iodinated contrast media needed for coronary CT angiography by at least half, according to several papers presented at the 2009 RSNA meeting.
