Use of Multispectral Optoacoustic Tomography to Diagnose Vascular Malformations.
JAMA Dermatol, 2018 Differential diagnosis of congenital vascular anomalies is challenging, and misdiagnosis is frequent. Vascular malformations are considered one of the most difficult vascular diseases to treat. A new imaging approach that visualizes anatomical features and quantitatively assesses molecular biomarkers noninvasively would aid diagnosis and monitoring of ...

Intravascular multispectral optoacoustic tomography of atherosclerosis: prospects and challenges [PDF]
Imaging in Medicine, 2012 The progression of atherosclerosis involves complex changes in the structure, composition and biology of the artery wall. Currently, only anatomical plaque burden is routinely characterized in living patients, whereas compositional and biological changes are mostly inaccessible.

Statistical Molecular Target Detection Framework for Multispectral Optoacoustic Tomography
IEEE Transactions on Medical Imaging, 2016 Statistical sub-pixel detection via the adaptive matched filter (AMF) has been shown to improve the molecular imaging sensitivity and specificity of optoacoustic (photoacoustic) imaging. Applied to multispectral optoacoustic tomography (MSOT), AMF assumes that the spatially-varying tissue spectra follow a multivariate Gaussian distribution, that the ...
