CT

Siemens Medical Solutions unveils a new CT platform this week at the RSNA meeting that company executives claim will put an end to the slice wars vendors have been fighting since the first multislice scanners were commercialized eight years ago.

Research studies published in November and December demonstrate there are no one-stop radiologic shops for the diagnosis of cardiovascular disease. Each modality is endowed with specific strengths that recommend it as the instrument of choice in specific clinical situations.

Fifteen years ago, a strike at the Chalk River Laboratories nuclear reactor in Ottawa, the main source of raw material for technetium-99m, was averted hours before the walkout was to take effect. Three years later, in 1995, a fuel rod got stuck. Fortunately, repairs caused only a four-day shutdown.

Canadian authorities order reactor start-upEmergency legislation issued by the Canadian government late Dec. 12 has ordered the restart of a nuclear reactor critical to the supply of technetium-99m. The Chalk River Laboratories reactor in Ottawa will require about a week before returning to full production of the medical isotope.

Physicians around the globe breathed a sigh of relief as the Canadian nuclear reactor responsible for producing a majority of the world’s medical radioisotopes was ordered to begin production again.

Radioactive microsphere therapy is gaining in popularity among specialists who deal with both primary and metastatic solid tumors in the liver. During the past two years, sessions dedicated to this therapeutic approach have been held in meetings of all major related specialties: interventional radiology, radiology, radiation oncology, surgical oncology, hepatobiliary surgery, nuclear medicine, and medical oncology.

Dr. Abass Alavi, a professor of radiology at the University of Pennsylvania, is the first nuclear medicine physician to receive the University of Bologna's prestigious laurea honoris causa. Alavi received the honorary doctorate in medicine and surgery for his contribution to the development of the radiotracer FDG.

As sure as the sun fades in the west, reimbursements for medical imaging set over time, a natural consequence of familiarity and increased demand, followed inevitably by increased productivity. But in 2006, the expected increase in demand did not happen in nuclear medicine.

Spectrum Dynamics unveiled at the RSNA meeting the commercial version of its D-SPECT Cardiac gamma camera, which promises to cut the time typically needed to do a SPECT heart scan by 75% or more. Time savings come from solid-state cadmium-zinc-telluride detectors and proprietary image reconstruction techniques, according to the company.

Late percutaneous coronary interventions do little goodIf you’re going to open a blocked coronary, do it quick or don’t bother, at least if you’re trying to have a long-lasting effect. Percutaneous coronary interventions (PCIs) using stents and balloons won’t make any difference in preventing second heart attacks, death, or development of heart failure if performed three or more days after a heart attack, according to research presented this week at the American Heart Association meeting.Toshiba launches faCTor64 studyGerman firm unveils dose shieldACR schedules ‘face’ time

As the end of the year closes in, vendors find themselves trailing far behind the previous year in the number of devices cleared by the FDA for marketing in the U.S.
