Water, Collagen, and Lipid Content in the Human Skin and Muscles Assessed with Near-Infrared Diffuse Reflectance Spectroscopy and Multi-Spectral Optoacoustic Tomography. [PDF]

Adv Sci (Weinh)
Authors present a novel approach combining multispectral optoacoustic tomography and diffuse reflectance spectroscopy for noninvasive assessment of body composition, including water, lipid, and collagen in skin and muscles. Its high molecular and spatial specificity offers improved diagnostic potential for conditions like obesity and sarcopenia ...

Multispectral optoacoustic tomography for the non-invasive identification of patients with severe anemia in vivo

Photoacoustics, 2022
The immediate diagnosis of severe anemia is crucial for patient outcome. However, reliable non-invasive point-of-care diagnostic tools for e.g., ICU monitoring are currently lacking. Using an advanced Multispectral Optoacoustic Tomography (MSOT) research

Non-invasive multispectral optoacoustic tomography resolves intrahepatic lipids in patients with hepatic steatosis

Photoacoustics, 2023
Hepatic steatosis is characterized by intrahepatic lipid accumulation and may lead to irreversible liver damage if untreated. Here, we investigate whether multispectral optoacoustic tomography (MSOT) can offer label-free detection of liver lipid content ...

Spatial quantification of clinical biomarker pharmacokinetics through deep learning-based segmentation and signal-oriented analysis of MSOT data

Photoacoustics, 2022
Although multispectral optoacoustic tomography (MSOT) significantly evolved over the last several years, there is a lack of quantitative methods for analysing this type of image data.

S1 guideline for imaging diagnostics for skin diseases. [PDF]

J Dtsch Dermatol Ges
Summary Non‐invasive imaging techniques allow a quick and easy in vivo examination of the skin with different penetration depths and resolution depending on the applied technology. Established methods such as dermoscopy and high‐resolution sonography of the skin have been an integral part of everyday life for decades.

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
