Intended Use
VitruvianScan is indicated for use as a magnetic resonance diagnostic device software application for non-invasive fat and muscle evaluation that enables the generation, display and review of magnetic resonance medical image data. VitruvianScan produces quantified metrics and composite images from magnetic resonance medical image data which when interpreted by a trained healthcare professional, yield information that may assist in clinical decisions.
Device Description
VitruvianScan is a standalone, post processing software medical device. VitruvianScan enables the generation, display and review of magnetic resonance (MR) medical image data from a single timepoint (one patient visit). When a referring healthcare professional requests quantitative analysis using VitruvianScan, relevant images are acquired from patients at MRI scanning clinics and are transferred to the Perspectum portal through established secure gateways. Perspectum trained analysts use the VitruvianScan software medical device to process the MRI images and produce the quantitative metrics and composite images. The device output information is then sent to the healthcare professionals for their clinical use. The metrics produced by VitruvianScan are intended to provide insight into the composition of muscle and fat of a patient. The device is intended to be used as part of an overall assessment of a patient's health and wellness and should be interpreted whilst considering the device's limitations when reviewing or interpreting images.
More Information

No
The summary describes image processing and quantitative analysis performed by trained analysts using the software, but there is no mention of AI, ML, or related concepts like deep learning, training sets, or performance metrics typically associated with AI/ML models.

No.
The device is described as a "diagnostic device software application" that "produces quantified metrics and composite images from magnetic resonance medical image data" to "assist in clinical decisions" and provide "insight into the composition of muscle and fat of a patient." It is not described as providing treatment or therapy.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states "VitruvianScan is indicated for use as a magnetic resonance diagnostic device software application." Furthermore, it mentions that the output "yield information that may assist in clinical decisions."

Yes

The device description explicitly states "VitruvianScan is a standalone, post processing software medical device." It processes existing MRI image data and does not include any hardware components.

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

Here's why:

  • IVD devices are used to examine specimens derived from the human body. This typically involves analyzing blood, urine, tissue samples, or other bodily fluids.
  • VitruvianScan processes medical image data (MRI images). It does not analyze biological specimens.
  • The intended use and device description clearly state that VitruvianScan works with magnetic resonance medical image data.

Therefore, VitruvianScan falls under the category of a medical image processing software device, not an IVD.
