Indications for Use
Your MAGNETOM system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and/or spectra, and that displays the internal structure and/or function of the head, body, or extremities. Other physical parameters derived from the images and or spectra may also be produced. Depending on the region of interest, contrast agents may be used. These inages and/ or spectra and the physical parameters derived from the images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis. Your MAGNETOM system may also be used for imaging during interventional procedures when performed with MR compatible devices such as in-room displays and MR Safe biopsy needles.
Device Story
MAGNETOM Avanto Fit is an MRI system utilizing magnetic resonance to generate cross-sectional images and spectra of human anatomy. Operated by trained healthcare professionals in clinical settings, the system acquires signals via RF coils, processed through the syngo MR XA50A software platform. New features include TSE MoCo (image-based motion correction for TSE sequences), automatic fiducial detection for breast biopsy, and AbsoluteShim (3-echo gradient echo shimming). The system supports interventional procedures using MR-safe accessories. Output images and derived physical parameters are interpreted by physicians to assist in clinical diagnosis. The device benefits patients by providing high-quality diagnostic imaging and supporting interventional guidance. Hardware upgrades include a redesigned cover and enhanced Electronic Power Cabinet (EPC).
Clinical Evidence
No clinical trials were conducted. Evidence consists of bench testing, software verification and validation, and sample clinical images to demonstrate image quality and performance of new/modified features compared to the predicate device. System safety was validated against IEC 60601-1, IEC 60601-2-33, and ISO 14971 standards.
