Positron Corporation (OTCBB:POSC). — Based on its recent analysis of the cardiac molecular imaging systems market, Frost & Sullivan recognizes Positron Corporation with the 2010 North American Award for New Product Innovation, for its pioneering cardiac positron emission tomography (PET) scanner, Attrius™. The Attrius™ was developed and optimized for molecular imaging of the heart, making it the ideal solution for cardiologists and hospitals looking to add high accuracy, cost effective imaging technology.
“The Positron Attrius scanner's design is optimized for cardiac imaging with a large list mode memory buffer allowing for concurrent flow, perfusion and dynamic function imaging. It does not need the use of CT unlike other expensive PET/CT market offerings.”
The nuclear cardiology imaging scene has been dominated by single photon emission tomography (SPECT) until recently when the imaging world was flipped upside down by the announcement of SPECT reimbursement cuts by the Centers for Medicare and Medicaid Services (CMS), combined with the world shortage of the molybdenum-99 isotope. Many in the industry are looking for new technologies to improve their diagnostic accuracy, improve patient outcomes, reduce patient radiation exposure all while adding to their bottom line. The elusive solution to this dire situation may lie in an already well established, underutilized imaging modality: PET.
While PET is a more costly procedure than the SPECT imaging, the use of PET in cardiac nuclear medicine has been shown to reduce long-term costs and resolve clinically complicated cases.. The accuracy of PET helps reduce the need for unnecessary angiograms. It can also reduce bypass surgeries by more accurately risk stratifying patients that may require the invasive procedure from those that might benefit from alternative therapies. This modality has also been shown to quantitatively monitor therapy, which helps provide personalized medicine plan for each patient. PET, specifically without a CT, has shown to have the lowest radiation exposure for the assessment of coronary disease.
“Positron's Attrius is the only dedicated PET available today for the thousands of cardiologists and hospitals looking for a solution to today's imaging challenges,” concludes Prasanna Kannan. “Implementing a PET program will allow cardiologists and hospitals to improve their diagnostic accuracy, reduce unnecessary downstream procedures, reduce patient radiation exposure, and practice more efficiency while improving their bottom line.”
Taking advantage of these trends, Positron strategically introduced the industry's first cardiac optimized PET scanner. Positron’s Attrius scanner is designed to provide a significantly lower cost of ownership as compared to PET/CT modalities and does not need additional space for electronics. It has a much smaller footprint, fewer boards, easier access to the detector modules, less power consumption, and automated tuning features imbibed within it. The product can easily integrate into practices of all sizes. The table limit was increased to 450lbs, permitting larger patients to be imaged. The table is also capable of loading patients from the front or back, improving the position options for imaging.
Further, Positron’s cardiac PET scanner is one of the highest 2D sensitivity systems on the market today. It features more uniformity achieved in its slice sensitivity, consistency in the quantitation from slice-to-slice, and the ability to more accurately define the locale of a lesion or perfusion defect. The system is designed to provide concurrent acquisition, reconstruction, image processing and display, as well as, other functions such as data archiving, without interference. The Attrius™ includes many key features in its design: uniform spatial resolution in all three planes; true dynamic and gated 82Rb acquisition capability; and a unique staggered detector design for optimal quantitative results.
