Intended Use

The MAGNETOM Avanto is indicated for use as magnetic resonance diagnostic devices (MRDD) that produces transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and/or spectra, and that display the internal structure and/or function of the head, body, or extremities. These images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis. The MAGNETOM Avanto 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 Avanto is 1.5 T closed superconducting magnetic resonance diagnostic device (MRDD). System acquires transverse, sagittal, coronal, and oblique cross-sectional images and spectroscopic data; displays internal structure and function of head, body, or extremities. Operated by trained clinicians in clinical settings; supports interventional procedures using MR-compatible accessories (e.g., biopsy needles, in-room displays). Physician interprets images/spectra to assist in diagnosis. Device utilizes modified gradient coil, RF body resonator, and magnet hardware similar to predicate systems. Safety and performance conform to NEMA and IEC standards for MR imaging.

Clinical Evidence

Bench testing only. No clinical data provided. Performance evaluated against NEMA standards for MR diagnostic devices, including signal-to-noise ratio, image uniformity, geometric distortion, slice profile, and high-contrast spatial resolution.

Technological Characteristics

1.5 T closed superconducting magnet system. Hardware includes modified gradient coil, RF body resonator, and magnet. Conforms to NEMA standards for MR performance and IEC standards for safety. Connectivity and software architecture not specified beyond standard MR diagnostic imaging functionality.

Indications for Use

Indicated for patients requiring diagnostic MR imaging of the head, body, or extremities, including interventional procedures. Applicable to all patient populations where MR imaging is clinically indicated and safe.

Regulatory Classification

Identification

A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).

Special Controls

*Classification.* Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Predicate Devices

• Siemens MAGNETOM 1.5 T Sonata (K993731)
• Siemens MAGNETOM 1.5 T Symphony (K971684)

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

#### Intended Use

The MAGNETOM Avanto is indicated for use as magnetic resonance diagnostic devices (MRDD) that produces transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and/or spectra, and that display the internal structure and/or function of the head, body, or extremities. These images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis.

The MAGNETOM Avanto 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 MAGNETOM Avanto System is a 1.5 T closed superconducting magnet designed scanner. It consists of the same types of hardware (with a modified gradient coil. RF body resonator and magnet) that are currently available with the MAGNETOM Sonata and Symphony systems.

#### Substantial Equivalence

The system is substantially equivalent to the following cleared medical devices:

| Predicate Device Name | FDA Clearance<br>Number | FDA Clearance Date |
|---------------------------------|-------------------------|--------------------|
| Siemens MAGNETOM 1.5 T Sonata | K993731 | 12/23/99 |
| Siemens MAGNETOM 1.5 T Symphony | K971684 | 08/05/97 |

#### General Safety and Effectiveness Concerns:

Operation of the MAGNETOM Avanto System is substantially equivalent to the commercially available MAGNETOM 1.5 T Sonata System and 1.5 T Symphony System. Specified by the FDA guidance document for MR Diagnostic Devices that will be evaluated. below are the safety parameter with the following levels:

Action Levels

- · Maximum Static Field
- · Rate of Change of Magnetic Field
- · RF Power Deposition
- Acoustic Noise Levels

Performance Levels

- · Specification Volume
- · Signal to Noise
- · Image Uniformity
- · Geometric Distortion
- · Slice Profile. Thickness and Gap
- High Contrast Spatial Resolution

The MAGNETOM Avanto will conform to the FDA recognized NEMA Standards for the measurement of performance and safety parameters and the international IEC standard for safety issues with Magnetic Resonance Imaging Devices. This will assure that the performance of this device can be considered safe and effective with respect to the currently available MAGNETOM Sonata and Symphony systems.
