S-scan is a Magnetic Resonance (MR) system that produces transverse, sagittal and coronal and oblique cross-section images of the limbs, joints and spinal column. It is intended for imaging portions of the upper limb, including the hand, wrist, forearm, elbow, arm and shoulder, imaging portions of the lower limb, including the foot, ankle, calf, knee, thigh and hip and imaging the cervical spine and the lumbar spine sections as portions of the spinal column.

S-scan images correspond to the spatial distribution of protons (hydrogen nuclei) that determine magnetic resonance properties and are dependent on the MR parameters, including spin-lattice relaxation time (T1), spin-spin relaxation time (T2), nuclei density, flow velocity and "chemical shift". When interpreted by a medical expert trained in the use of MR equipment, the images can provide diagnostically useful information.

Device Description

S-scan is a Magnetic Resonance (MR) system, which produces images of the internal structures of the patient's limbs and joints.

This 510(k) is to add the 4-channels Lumbar Spine coils 17 and 18. These are a four channels receiving coils, shaped for suitability to the areas under examination and designed to be matched to the patient's lumbo-sacral vertebrae; the coils are also morphologically adapted to the examined area to obtain a good Signal-to-Noise Ratio.

AI/ML Overview

The provided text is a 510(k) Summary for the 4-channels Lumbar Spine Coils 17 and 18 for the Esaote S-scan MRI system. It describes the device, its intended use, and its technological characteristics. However, it does not contain information regarding detailed acceptance criteria, a specific study proving the device meets those criteria, or any performance metrics like sensitivity, specificity, or reader improvement with AI assistance.

The document states: "Non-clinical testing of the S-scan system with the addition of the 4-channels Lumbar Spine Coils 17 and 18 demonstrated that it met performance requirements and is as safe and effective as the predicate devices." This is a high-level statement and does not provide the specifics requested in your prompt.

Therefore, I cannot populate the table or answer most of your questions based on the provided text.

Here's an assessment based on the available information:

1. A table of acceptance criteria and the reported device performance

Acceptance Criteria	Reported Device Performance
Not specified in text	"met performance requirements and is as safe and effective as the predicate devices."

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

Not specified in the text. The document mentions "non-clinical testing" but does not detail the size or nature of the test set, nor its provenance.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not specified in the text.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not specified in the text.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This document describes an MRI coil, not an AI-powered device. Therefore, an MRMC study comparing human readers with and without AI assistance is not relevant to this submission.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This pertains to an MRI coil, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Not specified in the text. The assessment of "performance requirements" would implicitly involve some form of ground truth or comparison, but the method is not described.

8. The sample size for the training set

Not applicable. This is an MRI coil, not an AI or machine learning model that requires a training set.

9. How the ground truth for the training set was established

Not applicable. This is an MRI coil, not an AI or machine learning model.

Device Description

S-scan is a Magnetic Resonance (MR) system, which produces images of the internal structures of the patient's limbs and joints.

Intended Use(s)

Technological Characteristics

The addition of the 4-channels Lumbar Spine Coils 17 and 18 to the S-scan system, reflected in this Special 510(k), does not alter the fundamental scientific technology of the S-scan system cleared via K080968. The technological characteristics of the 4channels Lumbar Spine Coils 17 and 18 are based on the Hitachi Medical Corporation AIRIS Elite Rapid Body Coil (K050307).

Performance Data

Non-clinical testing of the S-scan system with the addition of the 4-channels Lumbar Spine Coils 17 and 18 demonstrated that it met performance requirements and is as safe and effective as the predicate devices.

Dear Ms. Scott:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration. Iisting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Regulation Number and Section

§ 892.1000 Magnetic resonance diagnostic device.

(a)
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).(b)
