TomTec Goes MRI.NEW ORLEANS -- TomTec Imaging Systems, well known for its expertise in 3D and 4D echocardiography Echocardiography Definition Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart's valves and as well as for echo information management systems, extends its competence to MRI 1. (application) MRI - Magnetic Resonance Imaging. 2. MRI - Measurement Requirements and Interface. . TomTec pre-announces a solution for left ventricular analysis in cardiac magnetic resonance imaging magnetic resonance imaging (MRI), noninvasive diagnostic technique that uses nuclear magnetic resonance to produce cross-sectional images of organs and other internal body structures. (cMRI) at the ACC See adaptive cruise control. 2007 (American College of Cardiology The American College of Cardiology (ACC) is a nonprofit medical association established in 1949 to educate, research and influence health care public policy. The president for the 2006–2007 year is Steven E. Nissen. [1] The organization has 39 chapters in the U.S. ). Cardiac magnetic resonance is the gold standard technique for precise measurements of left ventricular volumes, function and mass. TomTec's new application should ease qualitative and quantitative assessment of cMRI data. The 4D LV-Analysis MR([c]) application, based on TomTecos successful 4D LV-Analysis([c]) software for echocardiography, uses MRI data sets to give doctors a comprehensive functional analysis of the left ventricle. Results include volumes, ejection fraction and a quantification of dyssynchrony. It also offers innovative (patent pending) analysis options like 3D Parametric Imaging (3DPI). This simplifies assessing dyssynchrony and localizing areas with delayed myocardial myocardial /myo·car·di·al/ (-kahr´de-al) pertaining to the muscular tissue of the heart. myocardial pertaining to the muscular tissue of the heart (the myocardium). contraction. The current gold standard method for functional LV analysis uses the 'short-axis slice summation'. The major difficulties of assessing mass and volumes with this method are in correctly including and excluding slices in the Mitral valve plane. To overcome these problems, TomTec's upcoming MR-solution combines short- and long-axis slices for a 3D left ventricular analysis. Like TomTec's 4D LV-Analysis solution for ultrasound, the 4D LV-Analysis MR application should offer doctors more precise measurements, as well as recently established parameters for quantifying dyssynchrony. This includes dyssynchrony cut-off values, such as the Systolic Systolic The phase of blood circulation in which the heart's pumping chambers (ventricles) are actively pumping blood. The ventricles are squeezing (contracting) forcefully, and the pressure against the walls of the arteries is at its highest. Dyssynchrony Index (SDI), which has the potential to help doctors select patients who are more likely to respond to Cardiac Resynchronization Therapy (CRT (1) (C RunTime) See runtime library. (2) (Cathode Ray Tube) A vacuum tube used as a display screen in a computer monitor or TV. The viewing end of the tube is coated with phosphors, which emit light when struck by electrons. ). SDI may also help to identify patients who are currently not considered for it, but may also benefit. Dr. Martin Hyca, TomTec's Clinical Marketing Manager adds, "The Systolic Dyssynchrony Index that TomTec developed with leading cardiologists is the first clinically validated parameter to separate responders from non-responders before pacemaker implantation. While this method was restricted until now to 3D ultrasound data, doctors may apply it in future even for patients that are difficult to examine with ultrasound, by using MR imaging. This may help even more patients benefit from this method." TomTec's cMRI application for 4D left ventricular analysis will be available from beginning of 2008. About TomTec Imaging Systems GmbH TomTec's headquarter is located in Munich, Germany. The company maintains close working relationships with many leading universities and ultrasound manufacturers. With a large installed base of more than 3000 systems, TomTec holds a leadership position in 2D and 3D/4D ultrasound. Its product line encompasses a wide range of 2D and 3D/4D technology for acquisition, analysis and reconstruction of medical image data. The product line is applicable to the fields of adult and paediatric cardiology as well as obstetrics and gynaecology Obstetrics and Gynaecology (often abbreviated to OB/GYN or O&G) are the two surgical specialties dealing with the female reproductive organs, and as such are often combined to form a single medical speciality and postgraduate training program. , radiology, and vascular diagnostics. |
