|Experimental: Optoacoustic imaging||
Device: MultiSpectral Optoacoustic Tomography
Multispectral Optoacoustic Tomography is a new emerging imaging technique which uses laser light to heat up molecules with a high pulsed laser. The molecules undergo thermal expansion and produces sound waves, which can be detected by special transducers. The device can pick up different signals in different wavelength to produce images with anatomic and biological information.
Primary Outcome Measures :
- Feasibility of MSOT imaging [ Time Frame: 12 months ]Feasibility of optoacoustic imaging to image the carotid artery and detect plaque formation in patients with symptomatic carotid artery disease.
- Ex vivo imaging [ Time Frame: 12 months ]Pre-operative detection of the atherosclerotic plaque in symptomatic carotid stenosis by the VEGF-targeted optical imaging agent optical imaging agent Bevacizumab-800CW using optoacoustic imaging subsequently correlated ex vivo for VEGF upregulation within the plaque indicative for increased angiogenesis.
Secondary Outcome Measures :
- Location of Fluorescence [ Time Frame: 12 months ]Presence of fluorescent signaling after excision of the atherosclerotic plaque ex vivo as determined by flatbed scanning and fluorescence microscopy.
