Siemens Healthineers (Erlangen, Germany) is presenting its two latest magnetic resonance tomographs designed for clinical and scientific use at RSNA 2022: Magnetom Cima.X2 with 3T field strength and Magnetom Terra.X1 with 7T. The 3T Magnetom Cima.X2 will use the company's strongest gradient with an amplitude5 of 200 mT/m and a slew rate of 200 T/m/s. This is 2.5 times higher than the currently strongest MRI from Siemens. Such a high gradient can help to better understand neurodegenerative diseases such as multiple sclerosis, even between relapses. So-called microstructures can be visible more clearly with the help of the strong gradients and could play a major role in understanding these diseases. Microstructures can hardly be visualized with classical MR imaging. Thus, treatment could be initiated earlier, improving the outlook for patients.
Magnetom Terra.X1 with a field strength of 7T represents the cutting edge of commercial MR imaging. The system will be the successor to Magnetom Terra, the first 7T clinical system, launched in 2017. The higher signal at 7T enables very high-resolution imaging for example of the head. This is particularly important in diseases where the detection of the smallest lesions can be crucial for the further treatment. Even in the field of knee imaging, the visibility of the smallest lesions can mean the decision for or against a surgery.
The new hardware and software from Magnetom Terra.X, named "Ultra IQ technology" by Siemens will significantly increase the capabilities of a 7T system: MR imaging at these extremely high field strengths can lead to a darkening of the image impression for instance at the lower part of the head. With Magnetom Terra.X, potentially relevant findings are clearly visible even along the edges of the image. While classic MR imaging works especially well in body regions with a lot of water in the tissue, other substances in the body, such as sodium, can be better visualized with high field strengths. This form of imaging goes beyond the mere representation of anatomy and enables a visualization of processes in the body such as the metabolism.
At RSNA 2022, Siemens is presenting NAEOTOM Alpha with Quantum Technology, the world’s first photon-counting CT that offers high-resolution images at minimal dose, spectral information in every scan, and improved contrast at lower noise. Siemens is also highlighting the Symbia Pro.specta SPECT/CT system with myExamCompanion that takes nuclear medicine department into the future. Every system includes intelligent SPECT/CT imaging and a fully integrated, intuitive user interface to give clinicians the power of more. Visitors to the Siemens booth at RSNA 2022 can also experience ARTIS icono, the company’s newest family of angiography systems. ARTIS icono is designed to help realize the potential for growth by enabling clinicians to offer a wide procedure mix in a single interventional suite. Siemens is also showcasing the ACUSON Family of ultrasound systems that empowers an ultrasound fleet solution to meet the clinical, operational, and financial needs for nearly any clinical area. From ultra-premium to compact, clinicians can experience 12 new transducers to expand clinical flexibility, and new advanced tools for improved diagnostic accuracy and workflows.
