CardioVations launches next in line of innovative heart stabilization systems
Full ArticleCardioVations, a division of ETHICON, has introduced the latest advancement to their line of heart stabilization systems. The EMBRACE Heart Stabilizer stabilizes desired areas of the heart, which in turn, creates a relatively stationary coronary artery during beating heart or "off-pump" coronary bypass (OPCAB) surgery and gives cardiac surgeons confidence for the most demanding procedures. The device uses stabilization "feet" to hold in place the epicardium parallel to the coronary artery in place, allowing them to bypass the blocked artery without resorting to the traditional method of stopping the heart and employing the heart/lung machine.
Viatronix to comment on recent JAMA study by Dr. Cotton on virtual colonoscopy reliability
Full ArticleDemonstrating clearly that not all virtual colonoscopies are equal, the study published in the December 2003 issue of the New England Journal of Medicine (NEJM) and the American Journal of Roentgenology, found the results obtained using the Viatronix V3D-Colon system for primary 3D reading to be equal to or better than optical colonoscopy results. One of the major differentiating factors between the two studies is that Dr. Peter Cotton's earlier study was based upon 2D as the primary read while Perry Pickhardt's trial published in the NEJM utilized live 3D as the primary read. The DOD multi-centre trial utilized 1233 patients as opposed to 615 patients utilized in the recently published study in the Journal of American Medical Association (JAMA) conducted by Dr. Peter Cotton. While Dr. Cotton's results have been disappointing, Dr. Perry Pickhardt's results published in NEJM for a much larger patient group are dramatically different.
Actuality Systems introduces first spatial 3D interventional planning tool for medicine
Full ArticleActuality Systems Inc., specialized in Spatial 3D visualization technology, has released Perspecta Medical, the first-ever Spatial 3D system for surgical and interventional planning. Perspecta Medical combines Actuality's award-winning Perspecta Spatial 3D display with innovative software that enables medical researchers to dramatically increase the value of existing imaging technologies by projecting interactive Spatial 3D images of CT, MRI, and PET data into a 360-degree multi-viewer visualization system.
Duke engineers receive grant for probing contortions of the heart's blood vessels
Full ArticleDuke biomedical engineers have received more than $2,2 million from the National Institutes of Health (NIH) to continue their explorations of how the complex moving and flexing of blood vessels during a heartbeat might contribute to heart disease. They are combining clinical images of beating hearts and computer software to perform challenging visualization studies of the coronary arteries that supply the heart with blood. Their goal is to determine whether there are certain motions that predispose vessel walls to thicken and ultimately reduce blood flow, or to develop a clot that blocks the vessel entirely.
New study reveals virtual colonoscopy as less sensitive than conventional colonoscopy
Full ArticleFindings of a new multicentre study by Cotton et al. published in the Journal of the American Medical Association comparing standard colonoscopy with CT colonography for the detection of colorectal cancer reveal that this technology, in the form used most often in the United States, while of significant interest, is not presently a viable option for routine colorectal cancer screening. The study utilized abdominal-pelvic CT scanning and the radiologists relied primarily on two-dimensional images but three-dimensional "fly-throughs" of the colon that simulate conventional colonoscopy were also evaluated.
