Summary

The goal of this observational study is to learn if the measures of tissue oxygenation from the MIMOSA Pro imaging device correlate to standard vascular assessment tools in patients who receiving a lower extremity vascular assessment. The main questions it aims to answer are: * Do the MIMOSA Pro tissue oxygenation measures correlate to Ankle-Brachial Index, Toe-Brachial Index, transcutaneous oximetry, and Doppler wave forms? * Do the MIMOSA Pro tissue oxygenation measures correlate with disease classifications for peripheral arterial disease, venous disease, and wound stage? * Is the MIMOSA Pro able to measure vascular status more often than other modalities? Participants will be asked to follow standard of care, and also allow for their legs to imaged by the MIMOSA Pro.

Detailed description

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.
