Optoacoustics and Optical: Complementary Modalities for Molecular Imaging
Judith Weber PhD, University of Cambridge
Alexa Hasenbach, University of Münster
Dr. Sheryl Roberts, Memorial Sloan Kettering
moreless information
Both optoacoustic and optical imaging are biophotonic molecular imaging technologies. In terms of performance, optical imaging can serve as an easy-to-use screening tool with limited resolution and depth penetration, while optoacoustic imaging can probe biological questions in more detail and at greater depth. In this webinar, three scientists present on their use of these complementary imaging modalities in a very diverse range of preclinical applications.

Innovations in Optoacoustic Imaging for Preclinical and Clinical Research
Neal Burton, PhD, Team Lead Applications, iThera Medical
moreless information
Optoacoustic imaging (OAI) is an innovative technique that facilitates the acquisition and analysis of structural, functional and molecular information in small animals. In OAI an animal is illuminated with pulsed laser light. Absorbance of light energy by tissue results in the emission of acoustic signals via the so-called 'photoacoustic effect' that describes the conversion of light energy into sound waves. Acoustic signals detected are then reconstructed to form a cross-sectional or volumetric image of light absorbance by the tissue of interest. This webinar focuses on the range of translational and multi-scale applications where biomedical research can benefit from OAI.

Imaging Tumor Function and Response with Optoacoustics
Dr Katja Haedicke, Application Specialist, iThera Medical
moreless information
Poor spatial resolution of current imaging modalities often limits monitoring of both angiogenesis and outcome of vascular-targeted therapies. So far, a detailed evaluation has only been possible using invasive approaches. RSOM (raster-scanning optoacoustic mesoscopy) takes advantage of the intrinsic optical properties of hemoglobin, high-frequency laser illumination, and detection of a broad ultrasound bandwidth. This provides non-invasive, high-resolution images of differentsized tumor vessels and facilitates detailed insights into dynamic responses to novel vascular-targeted therapies.

Liver Injury and Tumor Metastasis Imaging with MSOT
Prof Dr Shuizhu Wu, State Key Laboratory of Luminescent Materials & Devices, College of Materials Science & Engineering, South China University of Technology
moreless information
The development of accurate, non-invasive, fast-binding imaging contrast agents tailored to a specific pathological biomarker will deliver to the researcher & clinician tools to gauge the severity and progression of disease. By targeting specific enzymatic pathways through the use of activatable probes, it is possible to increase sensitivity and specificity of detection which, when combined with an imaging technology such as Multispectral Optoacoustic Tomography (MSOT), can give great insights into areas such as organ toxicity and cancer.
This webinar demonstrates how the optoacoustic effect can be used for imaging orthotopic tumors and for tumor biology investigation using activatable probes in combination with MSOT.

Multimodal cell tracking by combining gold nanorods and reporter genes
Dr Raphael Levy and
Dr Antonius Plagge, University of Liverpool, UK
moreless information
Understanding the fate of exogenous cells after implantation is important for clinical applications. Preclinical studies allow imaging of cell location and survival. Labelling with nanoparticles enables high sensitivity detection, but cell division and cell death cause signal dilution and false positives. By contrast, genetic reporter signals are amplified by cell division.This multimodal cell tracking approach could be applied widely for cancer and regenerative medicine research to monitor short- and long-term biodistribution, tumor formation and metastasis.
This webinar focusses on the use of MSOT to address the following topics:
- advantages and limitations of multimodal cell tracking approaches
- tracking cells immediately after injection into the blood stream of a mouse
- monitoring tumor growth over time using genetic reporters

Imaging tumor vascularization in high resolution with raster-scanning optoacoustic mesoscopy (RSOM)
Dr Katja Haedicke, Memorial Sloan Kettering Cancer Center, New York
moreless information
Tumor vasculature is the main source for oxygen and nutrient supply into the tumor tissue as well as the first route for tumor proliferation and metastasis formation. Therefore, it is of great interest to obtain non-invasive and high-resolution images of the entire tumor vascular network, not only to diagnose and characterize tumors but also to monitor treatment outcomes. In this context, the new imaging modality RSOM (raster-scanning optoacoustic mesoscopy) can highly improve the way we monitor and evaluate tumor vascularization by using the endogenous contrast of hemoglobin.
