S-scan is a Magnetic Resonance (MR) system that produces transversal, 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 portions of the spinal column, including the cervical and lumbo-sacral sections.
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.
The system is composed of these main parts:
- Patient positioning table.
- Magnetic unit with the display panel.
- Operating console that consists of the PC unit (including keyboard and mouse), the monitor and the operating table.
- Electronics box with filter panel.
The provided text is a 510(k) summary for the S-scan MRI system. It describes the device, its intended use, and technological characteristics compared to predicate devices. However, it does not contain information about acceptance criteria, specific performance studies, sample sizes, expert qualifications, ground truth establishment, or any comparative effectiveness studies (MRMC or standalone AI performance).
The document focuses on demonstrating substantial equivalence to existing MRI systems based on similar technology and intended use, rather than presenting a detailed performance evaluation with specific acceptance criteria as one might expect for a new diagnostic algorithm or AI-powered device.
Therefore, I cannot populate the requested tables and information based on the provided text. The document primarily highlights modifications to an existing G-scan MRI system (K042236) and its similarity to other predicate devices like the E-scan Opera (K060956) and Siemens Magnetom C! (K043030).
The "Comments" column in the "Technological Characteristics" table mentions that some S-scan features (like oversampling and gradient moment nulling) are already in place on other commercial scanners (e.g., MAGNETOM C! K043030). This suggests that the substantial equivalence argument relies on the established performance of similar technologies in predicate devices, rather than a new, independent performance study with defined acceptance criteria for the S-scan.

Device Description
Summary of G-scan modifications
The changes performed on the modified G-scan device (S-scan), with respect to the cleared version - G-scan K042236 -, are due to the improvement of the system performance. These modifications, that do not affect the intended use or alter the fundamental scientific technology of the device, are the following:
-
- A new patient table that can be moved only manually. Neither the patient table nor the magnet can rotate from horizontal to vertical position.
-
- A modified support to hold up the magnet and the gantry.
-
- A new display panel on the front of the magnet.
-
- Some different external covers due to the new patient table and support.
-
- Upgrading of the electronics.
-
- Two new receiving coils: DPA Lumbar spine coil N.10 and Cervical spine coil N.9
-
- Modified pulse sequences
-
- A modified version of the magnet poles and of the gradient coils.
-
- A new software release.

Dear Ms. Graham:
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, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Image /page/6/Picture/10 description: The image is a circular logo with the text "1906-2006" at the top. Below that is the acronym "FDA" in large, bold letters. Underneath the acronym is the word "Centennial" in a cursive font. There are three small dots arranged horizontally at the bottom of the logo. The logo appears to be a commemorative emblem for the 100th anniversary of the Food and Drug Administration.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean
Page 2 -
that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of this letter:

§ 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)
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.
