Intended Use

The MAGNETOM systems [MAGNETOM Aera, MAGNETOM Skyra, MAGNETOM Avanto, MAGNETOM Prisma and MAGNETOM Prisma] are 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 images 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. The MAGNETOM systems may also be used for imaging during interventional procedures when performed with MR compatible devices such as in-room display and MR-Safe biopsy needles.

Device Story

MAGNETOM systems (Aera, Avanto, Skyra, Prisma) utilize magnetic resonance imaging to acquire cross-sectional images and spectroscopic data. System inputs include radiofrequency signals and magnetic field gradients; software (syngo MR E11B) processes these inputs to reconstruct images/spectra. Operated by healthcare professionals in clinical settings. Output is visualized by physicians to assist in diagnosis or interventional procedure guidance. New features include DSI (diffusion-weighted q-space sampling), QISS (non-contrast MR angiography for PAD patients), and RT Dot Engine (workflow tool for radiation therapy planning). Benefits include improved diagnostic clarity, non-contrast vascular imaging, and streamlined planning workflows. System supports interventional procedures via MR-compatible hardware.

Clinical Evidence

No clinical tests conducted. Evidence consists of bench testing (SNR, image uniformity, heating, acoustic noise) and clinical images provided to support new coils and software features. Performance testing confirmed device functions as intended.

Technological Characteristics

MR diagnostic device; 1.5T and 3T field strengths. Software: syngo MR E11B. Features: DSI (q-space sampling), QISS (non-contrast MRA), RT Dot Engine. Hardware: Body 30/60 and Body 6 long coils. Conforms to IEC 62304, IEC 60601-1 series, and NEMA standards. Connectivity: Networked for clinical workflow.

Indications for Use

Indicated for patients requiring diagnostic MR imaging of the head, body, or extremities to visualize internal structure and function. Includes interventional procedure guidance using MR-compatible devices. No specific age or gender restrictions; contraindications include presence of non-MR-safe implants or devices.

Regulatory Classification

#### II. Safety and Effectiveness Information Supporting Substantial Equivalence

#### Intended Use

The MAGNETOM systems [MAGNETOM Aera, MAGNETOM Skyra", MAGNETOM Avanto", MAGNETOM Prisma and MAGNETOM Prisma""] are 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 images 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.

The MAGNETOM systems may also be used for imaging during interventional procedures when performed with MR compatible devices such as in-room display and MR-Safe biopsy needles.

#### Device Description

The subject device, synqo MR E11B system software, is being made available for the following MAGNETOM MR Systems:

- MAGNETOM Aera (24-channel configuration), .
- MAGNETOM Avanto™ ●
- MAGNETOM Skyra™, ●
- . MAGNETOM Prisma and
- . MAGNETOM Prisma™

Two new coils, Body 30/60 and Body 6 long, will be available for the subject device systems. The feature FREEZEit will be extended to other body regions. In addition to the abdomen region, FREEZEit will be extended to other regions such as the head, head and neck, pelvis, and chest region. . The syngo MR E11B SW also includes new sequences as well as minor modifications of already existing features. A high level summary of the new sequences can be viewed below:

#### DSI

With software version syngo MR E11B Siemens offers DSI for MAGNETOM Prisma, Prismall and Skyra" systems. The DSI option allows diffusion-weighted images to be acquired according to a DSI-compatible q-space sampling scheme.

#### Siemens 510(k) Premarket Notification

Syngo MR E11B for MAGNETOM Aera (24) (1.5T), MAGNETOM Avanto fit (1.5T), MAGNETOM Skyra fit (3T) and MAGNETOM Prisma/Prisma fit (3T)

{6}------------------------------------------------

DSI is based on sampling the "q-space", where "q-space" is defined in analogy to the "kspace" by the moment of the diffusion encoding gradients G: g = y/2π J G(t) dt.

While the Fourier transform of k-space data generates the image content, a Fourier transform of q-space data allows calculating a probability density function. This data provides information about the probability of a particle moving to a certain position in space within a certain time interval by diffusive motion.

The DSI Application is only available for MAGNETOM Prisma/Prisma™ and Skyraf" Systems.

# QISS evaluation

QISS (Quiescent-Interval Single-Shot) MR Angiography is a technique for non-contrastenhanced MR Angiography (non-CEMRA) that is particularly suited for examinations of patients with PAD. Since patients with PAD may also suffer from additional impairments such as renal dysfunction, the administration of contrast agent may often be unadvisable in this patient group. Siemens provides a manageable and optimized QISS workflow for imaging peripheral arteries, which can be easily adapted by the customer based on the patient's needs.

A new "Dot Engine" is provided to ease MRI acquisitions in Radiation Therapy.

# RT Dot Engine

RT Dot Engine is a new Dot Engine for aiding in Radiation Therapy planning. The RT Dot Engine does not provide new functionality, but collects and displays existing system information for the user. The RT Dot Engine comprises existing protocols, enhanced with the RT Planning Dot Add-in and the "MPR Planning" interaction step. The RT (Radiation Therapy) Dot Engine is used to ease MRI acquisitions of the head and the head/neck region with stereotactic frames or mask-based fixation techniques. RT Dot Engine is a workflow solution for acquiring MR images intended to aid in Radiation Therapy Planning. RT Dot engine helps streamline acquisition of MR images to be used along with any RT planning software that uses MR images in addition to CT images.

#### Conclusion as to Substantial Equivalence

synqo MR E11B for MAGNETOM Aera (24-channel configuration), MAGNETOM Avanto®", MAGNETOM Skyra®, MAGNETOM Prisma and MAGNETOM Prisma™ has the same intended use and the same basic technological characteristics as the predicate device, systems MAGNETOM Aera and MAGNETOM Skyra with syngo MR E11A, with respect to the magnetic resonance features and functionalities.

MAGNETOM Aera (24-channel configuration), MAGNETOM Avanto", MAGNETOM Skyra™, MAGNETOM Prisma and MAGNETOM Prisma™ with software syngo MR E11B will be used for acquiring MR images (transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and/or spectra.)

The differences between the MR systems with the subject device software and the predicate device SW, including the aforementioned new software and hardware options, give the subject device the same capabilities as the predicate device systems. While there are some minor technical features that vary with respect to the predicate device MR Systems, the conclusions from the non-clinical data suggest that the features with different technological characteristics from the predicate device bear an equivalent safety and performance profile as that of the predicate and reference devices.

syngo MR E11B for MAGNETOM Aera (24-channel configuration), MAGNETOM Avanto fit, MAGNETOM Skyra fit, MAGNETOM Prisma and MAGNETOM Prisma" is similar to the functionalities of the predicate device, and does not introduce any new issues of safety or effectiveness.

Therefore, Siemens is of the opinion that syngo MR E11 for MAGNETOM Aera (24channel configuration), MAGNETOM Avanto(4, MAGNETOM Skyra(*, MAGNETOM Prisma and MAGNETOM Prisma™ does not raise new questions of safety or effectiveness and is substantially equivalent to the currently marketed device
