Vioguard blasts germs off keyboardsHospital-associated infections are a growing concern for hospitals. Some 1.7 million people pick up infections each year while in hospitals. More than 99,000 die. While these infections may come from several sources, studies have shown that computer keyboards are a leading contributor. With the introduction of their first product, a self-sanitizing keyboard, Seattle-based Vioguard hopes to eliminate the keyboard as a vector of infection in hospitals.

Radiology Wife: US Arts 131 (Ultrasound Appreciation)Since ultrasounds are like opera but better, why are there no college classes offered in Ultrasound Appreciation alongside the other cultural arts? Since they don't yet exist I guess I should just offer a class myself. So here is the syllabus; let me know if you want to attend.

Cross-enterprise standard fosters imaging exchangeThe Integrating the Healthcare Enterprise initiative is intended to enable plug-and-play interoperability between clinical information systems from different vendors. Embraced by most major healthcare IT vendors, the IHE harnesses existing healthcare and IT standards such as DICOM and HL7 into integration profiles. The profiles amount to technical recipes for how standards must be implemented by vendors to ensure interoperability for specific tasks and problems faced by healthcare providers.

Clinicians weigh 64-slice CT's revolutionary potentialThe first announcements came at the 2003 RSNA meeting, informing the radiology community that 64-slice CT would soon be available for clinical practice. Initial site installations by Siemens Medical Solutions and GE Healthcare began shortly after, in late spring and early summer of 2004. The introduction of this new technology came as a surprise to many, since 16-slice CT had been widely available only since 2002.

Intervention: Needle biopsy, ablation score high in tumorsOver the past 15 years, improvements in biopsy needle design, sampling technique, and expertise of radiologists and cytopathologists have developed in concert with imaging technologies to make percutaneous needle biopsy (PNB) the most common interventional radiologic procedure. With skills refined from performing PNB, radiologists can now use a new and promising outgrowth of this technique-percutaneous tumor ablation-to safely and accurately place needles into a variety of malignant lesions to deliver local treatment.

Report from SNM: PET/CT restaging alters management for one-third of breast cancer casesFDG-PET/CT is gaining attention for its role in staging and restaging breast cancer. A trial from the Technical University of Munich, presented Sunday at the 2008 Society of Nuclear Medicine meeting in New Orleans, found that PET/CT detected local or distant recurrence in 67% of breast cancer patients and changed the management plan in 33% of the cases.

Is voice recognition a high-tech con game?I'm not a fan of voice recognition transcription, so I read Eric Trefelner's column, "Voice recognition misses a few beats" (May, page 104), with special interest. I'm also not naive enough to believe individual radiologists can, or should, stand in the way of this remarkable technology.

MR finds widespread clinical use in MS diagnosis, managementMR imaging has provided important insights into the pathophysiology of multiple sclerosis.1 Conventional MR scans afford only gross estimates of the extent and nature of tissue damage associated with MS,2 however, and the data correlate poorly with measures of concurrent disability in patients. Advances in MRI technology have improved the correlation of its findings with clinical status and increased the utility of MRI data as surrogate markers in monitoring disease progression and response to therapy.3 Newer techniques, such as magnetization transfer (MT), diffusion-weighted, and functional MRI, as well as proton MR spectroscopy and measures of brain and spinal cord atrophy, may help further elucidate MS pathology2 and provide opportunities for new treatment approaches.4
