RSNA 2009

Agfa 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.

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.

New 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.

Interest in computed and digital radiography was booming among vendors at RSNA 2009, as traditional providers of turnkey systems and components showed portfolios designed to appeal to cost-conscious buyers.

Korean researchers tested the ability of radiologists to spot CT images altered with commercially available software to introduce pathology and found that their ability to do so is no more certain than a coin flip.

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.

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.
