MAGNETOM Avanto Fit

The MAGNETOM Avanto Fit is a 1.5T magnetic resonance diagnostic device designed to produce detailed anatomical and functional images, including spectroscopic data, for diagnostic purposes across various body regions and for guiding interventional procedures. It utilizes updated hardware and new syngo MR XA50A software features, such as TSE MoCo for motion correction and AbsoluteShim for improved field homogeneity, to enhance image quality and expand clinical applications.

The MAGNETOM Avanto Fit is a 1.5 Tesla magnetic resonance diagnostic device (MRDD) designed to assist physicians in diagnosis by producing a variety of images and spectra. It can generate transverse, sagittal, coronal, and oblique cross-sectional images, as well as spectroscopic images and spectra, to display the internal structure and function of the head, body, or extremities. The system allows for the use of contrast agents depending on the area of interest and can also derive other physical parameters from the acquired data. Furthermore, the MAGNETOM Avanto Fit can be utilized for imaging during interventional procedures, provided MR-compatible equipment such as in-room displays and MR Safe biopsy needles are used. This system, running syngo MR XA50A software, represents an upgrade from the MAGNETOM Avanto, incorporating modified hardware and new software functionalities. Hardware updates include a redesigned cover accommodating BioMatrix components and an upgraded Electronic Power Cabinet. Key software enhancements introduce TSE MoCo for image-based motion correction in TSE sequences, automatic fiducial detection to improve MR Breast Biopsy procedures, and AbsoluteShim, a 3-echo gradient echo protocol for shimming. It also features a modified Fast GRE RefScan for optimized reference scanning in echo planar imaging. Non-clinical testing, including image quality assessments with sample clinical images, performance bench tests, and software verification, confirmed that the device performs as intended and its new/modified components maintain an equivalent safety and performance profile.
