Intravascular Photoacoustic and Autofluorescence Imaging for Detecting Intraplaque Hemorrhage: A Feasibility Study

Intraplaque hemorrhage (IPH), which is a trigger and conveys all blood components into the plaque, influencing the cholesterol crystal formation and retention, haemoglobin and oxidative enzymes, and blood-borne proteolytic activity. IPH is one of the key determinants for plaque vulnerability. In this paper, we proposed a dual-modality endoscope probe with a diameter of 1 mm for simultaneously detecting the lipid core and IPH, our system was...
