Intended Use

C-scan is a magnetic resonance (MR) system that produces transversal, sagittal and coronal and oblique crosssection images of the limbs and joints. It is intended for imaging portions of the arm, including the hand, wrist, forearm and elbow, but excluding the upper arm, and imaging portions of the leg, including the foot, ankle, call and knee, but excluding the thigh. C-scan MR 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 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 Story

C-scan is a magnetic resonance imaging (MRI) system for limbs and joints. It acquires MR signals from protons (hydrogen nuclei) to generate cross-sectional images (transversal, sagittal, coronal, oblique). The system consists of a patient positioning seat, an electronics/magnetic unit, and an operating console (PC, monitor, keyboard/mouse). It utilizes various pulse sequences (Spin Echo, Gradient Echo, Inversion Recovery, Turbo SE) to map T1, T2, proton density, flow, and chemical shift. Modifications from the predicate include upgraded electronics (DSP SHARC 21161), new pulse sequences, updated software, and mobile installation capability. The device is operated by trained medical professionals in clinical settings. Output images are interpreted by clinicians to provide diagnostic information, aiding in the assessment of musculoskeletal conditions. The system supports high-resolution imaging (up to 0.2 mm nominal spatial resolution) and improved signal-to-noise ratios via optimized sequences.

Clinical Evidence

Bench testing only. No clinical data provided. Substantial equivalence is based on technical comparisons of imaging performance, pulse sequence parameters, and hardware specifications.

Technological Characteristics

Magnetic resonance imaging system. Components: Patient positioning seat, electronics/magnetic unit, PC-based console. Upgraded electronics: DSP SHARC 21161 @ 100 MHz. RF system: 14-bit A/D conversion, 20 MHz sampling. Pulse sequences: Spin Echo, Gradient Echo, Turbo SE, IR, STIR, including 3D variants. Spatial resolution: up to 0.2 mm. Connectivity: PC-based, standard MR imaging interfaces. Power: 950-600 VA. Installation: Permanent or mobile.

Indications for Use

Indicated for MR imaging of limbs and joints, specifically arm (hand, wrist, forearm, elbow) and leg (foot, ankle, calf, knee). Excludes upper arm and thigh. For use by medical experts trained in MR equipment.

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.

Regulatory Class: II Product Code: 90 LNH Dated: April 2, 2004 Received: April 5, 2004

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 (PMA), 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean 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

{9}------------------------------------------------

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 the letter:
