Magnetom Essenza – Trendsetter in Quality and Cost Reduction

Magnetic resonance imaging with the newest technology and unbeatable low cost

Cost pressures are growing in healthcare. That's why Siemens Medical Solutions is investing in the development of innovative and affordable systems targeted at meeting the needs of hospitals and practices that want to cover the complete diagnostics area with a small budget. For this customer group Siemens has customized a 1.5 Tesla magnetic resonance imaging system (MRI) that is priced at up to several hundred thousand euros below the conventional 1.5 Tesla systems of this type. That makes Magnetom Essenza the least expensive brand new 1.5T MRI system. And the customer gets the newest technology at a much lower price than before. An example is the Tim (Total imaging matrix) technology, which offers the physician all the standard clinical applications with excellent image quality. Another innovation is the IsoCenter Matrix: installed at the center of the magnet, it is always in the correct position, thus giving a further guarantee of simple workflows and outstanding image quality.

"MAGNETOM Essenza will make MR imaging attainable for hospitals and practices that up to this time simply could not afford to provide these services to their patients, at least not to the extent and in the quality necessary. Our new system represents a paradigm shift. It will change the market permanently," predicted Walter Märzendorfer, Head of the Magnetic Resonance Division at Siemens Medical Solutions. "We have put a number of innovations together in this one system, including Tim, which our customers have valued for years, and created a package optimized for low total cost of ownership. We know there is enormous cost pressure on healthcare providers, so we looked for and found ways to make MRI more affordable.

Magnetom Essenza is a powerful and low-cost system that supports the clinical and financial success of its users. In addition to the low initial investment, savings of up to 25% can also be attained on installation costs for space, power requirements and construction. In part this is due to the light-weight 3.5 ton magnet, which even makes it possible to install the Magnetom Essenza on higher floors. If the system is replacing an existing MR system, it can reduce energy consumption up to 50% thanks to its high-performance electronics. Since the state-of-the-art magnet has zero helium boil-off, there is no need to regularly refill this expensive substance, and the system is always ready for operation.

Thanks to its powerful gradients (30mT/m), the new member of the Magnetom family delivers superior image quality for all clinical applications. Using Tim technology with Magnetom Essenza, the area of the patient to be examined can be covered with up to 25 seamlessly integrated coil elements that are read by 8 independent radiofrequency channels. Tim allows for flexibly combining up to four different coils, which make patient and coil repositioning virtually unnecessary. Tim also enables Parallel Imaging for reduced acquisition times. All of these benefits translate into workflow improvements as well as increased patient throughput, not to mention improving the profit situation. As an example, a complete examination of the entire central nervous system can be performed in less than ten minutes.

Another powerful new innovation is the IsoCenter Matrix coil. It is permanently positioned at the isocenter of the magnet and therefore always in position, ready to scan. The advantage: the user does not need to carry large, heavy spine coils any more and the patient preparation time is shortened. Additionally, by ensuring the correct positioning of the coil excellent image quality is also guarantied. The IsoCenter Matrix can be used in flexible combinations with other coils and works as a virtual 140 cm coil without patient repositioning in multi-step examinations.

Another new feature is the Focus Shoulder Array for optimum imaging of the shoulder. The coil's shim wing shifts the examination area of the magnet from the middle of the system to the shoulder, which would lie at the edge of the measuring volume without this technology.

Magnetom Essenza has a shorter system length than many conventional 1.5 Tesla MR systems. This means that the head and feet of the patient remain outside of the system in many cases, making the examination much more pleasant for the person in the bore.

According to Siemens' estimates, over 60 percent of the MRI systems sold worldwide in 2007 will be 1.5 Tesla systems. In order to meet the demands of the variety of institutions, from diagnostic imaging centers to municipal and university hospitals to research centers, Siemens Medical Solutions now offers four 1.5T systems, including its new addition: Magnetom Avanto, Magnetom Espree, Magnetom Symphony and Magnetom Essenza.

Siemens Medical Solutions is the world’s largest healthcare solution provider. The Group stands for innovative products and total solutions as well as a complete line of technical customer and consulting services. The entire spectrum of diagnostic and therapy imaging systems, molecular medicine and audiology up to and including IT solutions are covered in its line of products and services. The most recent acquisitions in the area of laboratory diagnostics (in vitro) – such as Diagnostic Products Corporation and Bayer Diagnostics – clear the way to becoming the first integrated diagnostics company worldwide. By offering these solutions, Siemens Medical Solutions enables its customers to achieve visible clinical and administrative results commonly referred to as “proven outcomes“. Innovations from Siemens optimize workflows in hospitals and practices as well as within the scope of an integrated healthcare system, leading to increased efficiency. Med currently has over 41,000 employees worldwide and is represented in more than 130 countries. During fiscal 2006 (ending on September 30), Med achieved a total sales volume of €8.23 billion and incoming orders totaling €9.33 billion according to U.S. GAAP. The Group earnings amounted to €1.06 billion. For more information, go to: www.siemens.com/medical
