Multispectral Optoacoustic Tomography (MSOT) of Human Breast Cancer [PDF]

Clinical Cancer Research, 2017
Abstract Purpose: In a pilot study, we introduce fast handheld multispectral optoacoustic tomography (MSOT) of the breast at 28 wavelengths, aiming to identify high-resolution optoacoustic (photoacoustic) patterns of breast cancer and noncancerous breast tissue.

Noninvasive Imaging of Colitis Using Multispectral Optoacoustic Tomography. [PDF]

J Nucl Med, 2017
Currently, several noninvasive modalities, including MRI and PET, are being investigated to identify early intestinal inflammation, longitudinally monitor disease status, or detect dysplastic changes in patients with inflammatory bowel disease. Here, we assess the applicability and utility of multispectral optoacoustic tomography (MSOT) in evaluating ...

Spatial and Spectral Mapping and Decomposition of Neural Dynamics and Organization of the Mouse Brain with Multispectral Optoacoustic Tomography

Cell Reports, 2019
Summary: In traditional optical imaging, limited light penetration constrains high-resolution interrogation to tissue surfaces. Optoacoustic imaging combines the superb contrast of optical imaging with deep penetration of ultrasound, enabling a range of ...

Multispectral optoacoustic tomography of myocardial infarction

Photoacoustics, 2013
To investigate the feasibility of a high resolution optical imaging strategy for myocardial infarction.Near-infrared approaches to imaging cardiovascular disease enable visualization of disease-associated biological processes in vivo. However, even at the scale of small animals, the strong scattering of light prevents high resolution imaging after the ...
