Photoacoustic imaging (or optoacoustic imaging) is an upcoming biomedical imaging
modality availing the benefits of optical resolution and acoustic depth of penetration. With its
capacity to offer structural, functional, molecular and kinetic information making use of either
endogenous contrast agents like hemoglobin, lipid, melanin and water or a variety of
exogenous contrast agents or both, PAI has demonstrated promising potential in a wide
range of preclinical and clinical applications. This review provides an overview of the rapidly …
