Abstract: The use of multimodal imaging as a tool to assess the in vivo pharmacokinetics and biodistribution of nanoparticles is important in drug development and imaging-guided therapy. The current study reports the use of combined micro-CT and optical imaging FMT to quantitatively assess the whole body and intratumoural distribution of a nano-sized liposome-based CT/optical imaging probe carrying iohexol and Cy5.5. Micro-CT was used to guide the FMT tumour delineation and signal correction. This investigation demonstrates the critical role micro-CT can play in guiding FMT-based quantification of distribution. As well the combination of CT and optical imaging enable visualization of the liposomes at the whole body, tumor and cellular levels with high sensitivity and excellent anatomical background. Such non-invasive assessment of therapeutic distribution at the macro and micro scale is necessary for implementation of personalized medicine including image-guided patient stratification and real-time adjustment of therapeutic dose.
