The ability to perform cell tracking using x-ray computed tomography combined with gold nanoparticles has been demonstrated recently on ex-vivo samples using different malignant and non-malignant cell lines. Here we proved the concept of the method for in-vivo assessment in a small animal model of malignant brain tumours. The limitations of the method due to radiation dose constraints have been investigated using Monte Carlo simulations. Taking into consideration different x-ray entrance doses and the spatial resolution, the visibility of the cell clusters have been evaluated. The results of the experiments conducted on mice implanted with F98 tumour cells confirmed the prediction of the Monte Carlo calculations. Small clusters of cells exogenously loaded with gold nanoparticles could be visualized using our in-vivo method.
