Noninvasive Imaging of Colitis Using Multispectral Optoacoustic Tomography [PDF]

Journal of Nuclear Medicine, 2016
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 ...

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 ...

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 ...

In vivo tracking of orally-administered particles within the gastrointestinal tract of murine models using multispectral optoacoustic tomography

Photoacoustics, 2019
While particle carriers have potential to revolutionize disease treatment, using these carriers requires knowledge of spatial and temporal biodistribution.

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.

Multispectral Optoacoustic Tomography of Brown Adipose Tissue

, 2018
MSOT has revolutionized biomedical imaging because it allows anatomical, functional, and molecular imaging of deep tissues in vivo in an entirely noninvasive, label-free, and real-time manner. This imaging modality works by pulsing light onto tissue, triggering the production of acoustic waves, which can be collected and reconstructed to provide high ...
