FDA Clears Siemens’ New 3T MRI

Siemens Healthcare announced FDA approval of their MAGNETOM Prisma, a 3T MRI scanner designed to provide high spatial and temporal resolution, particularly in highly demanding applications.

The MAGNETOM Prisma features XR Gradients, which combine 80 milliTesla per meter with a 200T-per-meter-per-second slew rate to offer a configuration unavailable in any other commercial whole-body system. The system is designed to maintain precision throughout long, demanding applications such as functional MRI. The system’s first-to-market Diffusion Spectrum Imaging (DSI) acquisition enables the user to potentially resolve fine anatomical details of the brain such as crossing white-matter fibers, the company said.

MAGNETOM Prisma’s benchmark homogeneity and advanced shimming solutions allow for finer, more effective compensation of patient-induced field disturbances. The MAGNETOM Prisma has Siemens’ Dot (Day optimizing throughput) engines that enable consistency for research applications and clinical work, the company said. The Dot engine brings automation and reproducibility to investigations across subjects, time points, and institutions.

Siemens will offer onsite upgrades to the MAGNETOM Prisma to customers who have already installed the MAGNETOM Trio.
