NCT04456400
The clinical investigation aims to generate clinical data to support the use of Multispectral Optoacoustic Tomography (MSOT) in clinical practice, its inclusion in diagnostic guidelines and to support its reimbursement, specifically to * Further validate the application with respect to including ulcerative colitis patients * Prepare a study protocol for large-scale clinical validation study in inflammatory bowel disease (IBD) * Successfully execute the clinical validation study
NCT04748965
This study aims to investigate the utilization of intravascular imaging in treatment of tibial vessels in peripheral artery disease and critical limb ischemia (CLI). The primary goal is to compare optical coherence tomography (OCT) with traditional digital subtraction angiography (DSA) in determining best treatment strategy and vessel optimization, in an effort to improve long term patency and successful wound healing in CLI. Secondary comparison with intravascular ultrasound (IVUS) is undertaken when clinically feasible. The hypothesis is that the adjunctive use of intravascular imaging will affect vessel sizing and anticipated treatment modalities, and therein affect the long term primary patency rates.
