Project description
Non-invasive detection of gut inflammation
Multispectral optoacoustic tomography (MSOT) is an imaging technique that combines optical and acoustic methods to visualise tissues and structures within the body. It is non-invasive and provides high-resolution images with functional and molecular information. Funded by the European Research Council, the IseeG project aims to develop enhanced contrast agents for imaging early inflammatory processes in the gastrointestinal tract using MSOT. Currently, detection of inflammation is carried out using endoscopic methods that have limited applicability. The idea is to deliver oral dyes that can flag inflamed areas and allow the dynamic visualisation of the intestinal tract in a non-invasive manner.
Objective
"The aim of this project is to functionalize contrast agents for multispectral optoacoustic tomography (MSOT) - a molecular ""sensitive"" ultrasound imaging technique - to develop a new targeted imaging approach for the early localisation of inflammatory processes.
Inflammatory processes in the gastrointestinal tract often act like a Trojan horse - while camouflaging themselves with diffuse clinical symptoms, they may rapidly progress into life-threatening complications. To date, it has been difficult to precisely localize them in their early stages, and their detection remains the domain of invasive endoscopy. The invasive nature of this method not only restricts its use for early disease detection, but is a major limitation for repetitive or high-risk applications. MSOT uses laser light excitation and ultrasound detection to resolve different chromophores such as haemoglobin, lipids, and other metabolic parameters at depths of several centimetres. While we were using the response from endogenous chromophores for translational to a range of potential clinical applications, we discovered that dyes delivered via the oral route enable the dynamic visualization of the entire intestinal tract. This molecular-sensitive approach has the advantage that such contrast agents are not absorbed systemically and undergo excretion largely unchanged. Based on this, I hypothesize that it is possible to functionalize such contrast agents in order to put a molecular flag on inflamed areas in the gastrointestinal tract. After characterizing potential imaging targets in the intestinal lumen and developing imaging agents, we will take a translational research approach, moving from cells through small and large experimental animal models back to the human system. This research at the frontiers of medicine and physics may pave the way to non-invasive early detection and personalized treatment strategies while minimizing the procedural risk for affected patients."
