This submission consists of a new Magnetic Resonance Imaging system which is based primarily on the cleared EXCELARTTM (K990620) with the following new functions added to the standard system. • Pianissimo: Gradient acoustic reduction system • QD Whole Body coil • QD Head coil • QD C/T/L Spine Array coil • 18.1" LCD flat screen monitor • Increase of SAR limit from

This document is a 510(k) Premarket Notification for a Magnetic Resonance Diagnostic Device Accessory (MRI system), specifically the EXCELART™ with Pianissimo. The submission is focused on demonstrating substantial equivalence to a predicate device, rather than proving performance against specific acceptance criteria for a novel AI algorithm or diagnostic tool.

Therefore, many of the requested categories (e.g., sample sizes for test/training sets, ground truth establishment, expert qualifications, MRMC studies, standalone performance) are not applicable or not explicitly detailed in this type of submission for this kind of device. The focus here is on the safety and performance characteristics of the MRI system itself and its accessories.

Here's a breakdown based on the provided text, indicating what information is available and what is not:

1. Table of Acceptance Criteria and Reported Device Performance

For an MRI system, performance is generally evaluated against safety parameters and imaging capabilities rather than diagnostic accuracy metrics. The document specifies safety parameters and imaging volumes.
