Intended Use
The SpinTech, Inc. SPIN-SWI application is intended for use in the post-acquisition image enhancement of MRI acquired 3D gradient-echo images of the brain. When used in combination with other clinical information, the SPIN-SWI application may aid the qualified radiologist with diagnosis by providing enhanced visualization of structures containing venous blood such as cerebral venous vasculature.
Device Description
The SPIN-SWI device includes a post-processing algorithm that enhances the contrast of tissues with different susceptibilities from 3D gradient-echo MRI images. The susceptibility of a biological tissue relates to the concentration of iron within it. which can be present in the form of deoxyhemoglobin, ferritin, hemosiderin, or other molecules. An MRI scan results in both magnitude and phase images. While magnitude is most commonly used clinically, the phase information can also be useful as it relates directly to the magnetic field. When tissues or objects of differing magnetic susceptibility are present, they perturb the field around them. This effect can be seen directly from phase images. While this perturbation already leads to signal loss in magnitude images, thus creating contrast, the phase information can still be used to enhance this contrast for local susceptibility changes. Enhancing this contrast allows us to visualize structures containing venous blood such as cerebral venous vasculature that may have not been visible prior to enhancement. Some technical challenges of SWI include eliminating the effects of unwanted background fields and choosing parameters to create optimal contrast. SPIN-SWI software works in conjunction with an FDA cleared third-party DICOM viewer as an image postprocessing solution in a PC workstation. The DICOM viewer (ORIS Visual) was FDA cleared on 4/29/2010 via K100335 and is used to transmit DICOM data and display the input and output images, the SPIN-SWI software application performs the SWI post-processing on 3D GRE input images to reconstruct the SWI output images.
More Information

No
The description focuses on a post-processing algorithm based on magnetic susceptibility principles and does not mention AI or ML.

No.
The device is described as an image post-processing application intended to enhance MRI images for diagnosis, not to treat or cure a disease or condition.

Yes

Explanation: The "Intended Use / Indications for Use" section states that the device "may aid the qualified radiologist with diagnosis".

Yes

The device is described as a "post-processing algorithm" and "software application" that works in conjunction with an FDA cleared third-party DICOM viewer on a PC workstation. There is no mention of any hardware component being part of the device itself.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs are used to examine specimens from the human body. The description clearly states that the SPIN-SWI application processes MRI images of the brain. It does not analyze blood, tissue samples, or any other biological specimens taken from the body.
  • The intended use is post-acquisition image enhancement. The device works with existing MRI data to improve visualization, not to perform a test on a biological sample.

The device is a medical image processing software intended to aid in diagnosis by enhancing existing imaging data. This falls under the category of medical devices, but not specifically In Vitro Diagnostics.

4. DEVICE DESCRIPTION

The SPIN-SWI device includes a post-processing algorithm that enhances the contrast of tissues with different susceptibilities from 3D gradient-echo MRI images. The susceptibility of a biological tissue relates to the concentration of iron within it. which can be present in the form of deoxyhemoglobin, ferritin, hemosiderin, or other molecules.

An MRI scan results in both magnitude and phase images. While magnitude is most commonly used clinically, the phase information can also be useful as it relates directly to the magnetic field. When tissues or objects of differing magnetic susceptibility are present, they perturb the field around them. This effect can be seen directly from phase images. While this perturbation already leads to signal loss in magnitude images, thus creating contrast, the phase information can still be used to enhance this contrast for local susceptibility changes.

Enhancing this contrast allows us to visualize structures containing venous blood such as cerebral venous vasculature that may have not been visible prior to enhancement. Some technical challenges of SWI include eliminating the effects of unwanted background fields and choosing parameters to create optimal contrast.

SPIN-SWI software works in conjunction with an FDA cleared third-party DICOM viewer as an image postprocessing solution in a PC workstation. The DICOM viewer (ORIS Visual) was FDA cleared on 4/29/2010 via K100335 and is used to transmit DICOM data and display the input and output images, the SPIN-SWI software application performs the SWI post-processing on 3D GRE input images to reconstruct the SWI output images.
