Use of Hyperspectral Imaging in a Clinical Setting

Hyperspectral imaging provides a fast, noninvasive method to assess levels of perfusion within the microvascular system (1). This model has been shown useful in a variety of applications, including the assessment of the presence and severity of peripheral artery disease (3). The same hyperspectral imaging technology has also been used to determine probable wound healing outcomes and to predict wound formation based on levels of oxyhemoglobin. This work has established ranges of oxyhemoglobin levels that corresponded to adequate and inadequate perfusion (4,5). The aim of this prospective study was to investigate the use of hyperspectral imaging at the Point of Contact to identify and follow patients through vascular intervention. This study found high correlation between hyperspectral screening results and Ankle Brachial Index and/or Doppler Ultrasound. The study also found Hyperspectral Imaging provided confirmation of increased perfusion to the plantar metatarsal post-intervention. In conclusion, hyperspectral Imaging is a viable diagnostic tool for assessment of perfusion pre- and post-intervention.
