MAGNETOM Avanto fit; MAGNETOM Skyra fit

The MAGNETOM Avantofit and MAGNETOM Skyrafit systems, incorporating the syngo MR XA61A software, are magnetic resonance diagnostic devices that utilize new and modified hardware, including specialized coils and updated computer systems, to acquire detailed anatomical and functional images. These systems employ advanced software features such as the Open Recon Framework, Physiologging, and the GRE_PC pulse sequence to refine image quality, data acquisition processes, and overall diagnostic utility.

The MAGNETOM Avantofit and MAGNETOM Skyrafit are magnetic resonance diagnostic devices (MRDD) designed to produce a variety of cross-sectional images (transverse, sagittal, coronal, oblique), spectroscopic images, and/or spectra. These outputs display the internal structure and/or function of the head, body, or extremities, and when interpreted by a trained physician, may assist in diagnosis. The systems can be used with contrast agents and are also capable of imaging during interventional procedures if performed with MR-compatible devices. The described updates to these systems center on the introduction of the syngo MR XA61A software, which encompasses new and modified hardware and software components aimed at enhancing their imaging capabilities and performance. Key hardware modifications for both systems include updated host computers (syngo MR Acquisition Workplace and syngo MR Workplace), with the MAGNETOM Skyrafit also receiving an updated MaRS (Measurement and Reconstruction System) computer. New hardware introduced consists of several coils: the Flex Loop Large (for Avantofit only), UltraFlex Large 18, UltraFlex Small 18, and Contour 24. Significant software enhancements include the new GRE_PC pulse sequence, a Physiologging feature for use with EPI2D_BOLD and EPI2D_PACE sequences, and an Open Recon Framework for image reconstruction. Additionally, the BEAT_nav feature was renamed, and the myExam Angio Advanced Assist (Test Bolus) was modified for the MAGNETOM Skyrafit. The performance of these new and modified components was assessed through non-clinical testing, including software verification and validation, and evaluation of sample clinical images, without conducting new clinical trials for these specific updates.
