Correlating Multispectral Near-Infrared Imaging to Standard Vascular Diagnostics

Observational non-interventional study to assess the use of multispectral near-infrared (MS-NIR) imaging as an adjunct tool in the wound center. No clinical decisions will be made based on information obtained through the use of the MIMOSA device. Objectives are to correlate tissue oxygen saturation (StO2) by MS-NIR to measures by standard vascular diagnostic tools, including ankle-brachial index (ABI), toe-brachial index (TBI), transcutaneous oximetry, Doppler waveforms. Also to assess the ability of MS-NIR to support the classification and grading severity of patients' peripheral artery disease (PAD), venous disease and wound healing and to evaluate the clinical workflow utility of MS-NIR as an adjunct tool in the wound center. The study will recruit patients 18 years old and older, are undergoing an ankle-brachial index exam and recently had/will have further vascular assessment, as per standard of care (inc. transcutaneous oxygen pressure, Doppler waveforms). Participants will be asked to allow for imaging of their lower extremities with the MIMOSA Pro. Investigator will assess participants on their disease and wound status. They will also perform vascular assessments mentioned above as per standard of care. Participants will be followed for 2 months as per regularly scheduled visits. The standard vascular assessment results and disease/wound status will then be correlated with the measures from the MIMOSA Pro.
