Worldwide innovation on the MRI high-field market: 70 cm magnet bore for a 3Tesla system
Once again Siemens Medical Solutions sets new benchmarks for diagnostic imaging. For the first time worldwide the Magnetom Verio magnetic resonance imaging system (MRI) combines 3 Tesla ultra-high field technology with a 70 centimeter magnet bore for the patient. Thus, Siemens again demonstrates its innovative leadership in open MRI systems. In 2004 the company presented Magnetom Espree, an MRI system where the then standard 60 cm magnet bore was extended to 70 cm for the first time. The Magnetom Verio combines 3 Tesla, 70 centimeters and Tim (Total imaging matrix) technology to provide excellent image quality, superior diagnostic quality and exceptional patient comfort. Moreover, the design of the system facilitates the diagnosis of obese and claustrophobic patients, or in some cases, makes the examination possible in the first place. Tim technology simplifies workflows and increases patient throughput.
The 3T market is one of the most quickly growing markets. According to Siemens' estimates, over 13 percent of the MRI systems sold in 2007 will be 3 Tesla systems. While at first, ultra-high-field MRI systems were of interest primarily in research due to their higher image resolution, they have entered clinical routine to an increasing extent in recent years.
Magnetom Verio meets every market demand with a single system: increasing requirements for patient comfort and the growing demand for MRI systems supporting high image quality and efficient workflow.
“For the first time Siemens combines a field strength of 3 Tesla with a magnet bore of 70 centimeters. This is an enormous improvement for patients who have, for example, felt uncomfortable with the confined space during the examination,” explains Walter Märzendorfer, Head of the Magnetic Resonance Division at Siemens Medical Solutions. “Moreover, we have managed to develop the shortest 3 Tesla system currently available on the market. This makes lying inside the MRI system more comfortable, as the patient's head can remain outside the system for many examinations. At the same time, we continue to provide outstanding system performance without any compromise to image quality.”
Due to the system’s bore of 70 cm in diameter, the average distance between eyes and magnet is 30 cm, greatly alleviating concerns of claustrophobia in many patients. In addition, the wider space makes it possible to scan patients who could not be examined with the MRI system in the past. For example, patients suffering from kyphosis, limited mobility, or pain, as well as pediatric and obese patients fall into this category. Patients dependent on medical devices, patients in intensive care and those having to undergo intraoperative procedures likewise benefit from the 3 Tesla and open bore technology. As the patients are less likely to move during the examinations than usual, the MRI system provides exceptionally good image quality.
The workflow is more efficient in every respect, thanks to Tim technology. The flexibility of Tim technology allows for combining up to 102 seamlessly integrated matrix coil elements with up to 32 independent radiofrequency channels. Magnetom Verio with Tim therefore enables extremely accurate imaging for examinations of individual organs as well as for whole-body examinations. Tim drastically reduces acquisition times by allowing parallel imaging in all slice orientations.
Magnetom Verio enables fast and reliable evaluation of complex pathologies for easy treatment, even of difficult patients. Even advanced applications can be performed as part of the daily routine. syngo DTI (Diffusion Tensor Imaging), for example, provides complete 3D views of neuronal fibers just by pressing a few buttons.
With a system length of only 173 cm, Magnetom Verio is currently the shortest 3T MRI system on the market worldwide, while having the footprint of a 1.5 Tesla MRI system. Furthermore, it is equipped with a comparably ultralight magnet of only six tons. Thanks to the system’s smaller dimensions and lower weight, the installation costs for the Magnetom Verio are minimized. 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.
Besides the Magnetom Verio, the Siemens portfolio includes another 3T system, the Magnetom Trio.
