Multispectral Optoacoustic Tomography (MSOT) Characterization in Resolving Molecular Biomarkers

, 2009
Fluorochromes are essential biological reporters in many areas of biomedical research and, in particular, molecular imaging applications. We demonstrate the basic performance characteristics of multispectral optoacoustic tomography in resolving fluorochromes in tissue-mimicking phantoms.

Volumetric real-time multispectral optoacoustic tomography of biomarkers

Nature Protocols, 2011
Multispectral optoacoustic tomography (MSOT) has recently been developed to enable visualization of optical contrast and tissue biomarkers, with resolution and speed representative of ultrasound. In the implementation described here, MSOT enables operation in real-time mode by capturing single cross-sectional images in

Multispectral optoacoustic tomography at 64, 128, and 256 channels

Journal of Biomedical Optics, 2014
Optoacoustic (photoacoustic) imaging has already showcased the capacity to offer high-resolution small animal visualization in vivo in a variety of cancer, cardiovascular, or neuroimaging applications. In particular, multispectral optoacoustic tomography (MSOT) has shown imaging along the spectral and the time dimensions, enabling sensing of multiple ...

Multispectral optoacoustic tomography of benign parotid tumors in vivo: a prospective observational pilot study [PDF]

Scientific Reports
Parotid lumps are a heterogeneous group of mainly benign but also malignant tumors. Preoperative imaging does not allow a differentiation between tumor types. Multispectral optoacoustic tomography (MSOT) may improve the preoperative diagnostics.

Croconaine-based nanoparticles enable efficient optoacoustic imaging of murine brain tumors

Photoacoustics, 2021
Contrast enhancement in optoacoustic (photoacoustic) imaging can be achieved with agents that exhibit high absorption cross-sections, high photostability, low quantum yield, low toxicity, and preferential bio-distribution and clearance profiles. Based on
