FDA clears 3T MRI system with enhanced functional imaging

By 

December 19, 2013 - The U.S. Food and Drug Administration (FDA) has cleared the MAGNETOM Prisma, a 3 Tesla (3T) magnetic resonance imaging (MRI) scanner by Siemens Healthcare, which is capable of high spatial and temporal resolution to achieve outstanding image quality, particularly in demanding applications.

The system is designed to address demanding clinical and research challenges display functional information and enable the visualization of details in the smallest anatomical structures.

The MAGNETOM Prisma’s XR Gradients system offers diffusion spectrum imaging (DSI) acquisition that enables the user to potentially resolve fine anatomical details of the brain such as crossing white-matter fibers.

The MAGNETOM Prisma features XR Gradients, which combine 80 milliTesla per meter (mT/m) with a 200T-per-meter-per-second (T/m/s) slew rate to offer a configuration unavailable in any other commercial whole-body system. The MAGNETOM Prisma’s XR Gradients is the system’s robust design supports the demanding applications, such as functional MRI (fMRI). The MAGNETOM Prisma’s XR Gradients system offers diffusion spectrum imaging (DSI) acquisition that enables the user to potentially resolve fine anatomical details of the brain, such as crossing white-matter fibers.


Image quality is further enhanced by the MAGNETOM Prisma’s homogeneity and shimming solutions for finer, more effective compensation of patient-induced field disturbances. Together, these features provide the user with an basis for cardiac and body imaging, as well as applications such as spectroscopy.


The MAGNETOM Prisma possesses Siemens’ Dot (Day optimizing throughput) engines made for consistency, important in research applications and clinical work. The Dot engine brings automation and reproducibility to investigations across subjects, time points, and institutions, raising the integrity of longitudinal studies and multi-site research projects.


Siemens will offer onsite upgrades to the MAGNETOM Prisma to customers who have already installed the MAGNETOM Trio, a 3T MRI system with Tim (Total imaging matrix) technology.
