Research summary

The current gold standard for clinical tumor diagnosis and characterization is tumor pathology through invasive biopsy. However, since only a sample of tumor is obtained, the extraced cells might only partically refelct the tumor characteristics, especially in heterogeneous tumors. My research interest is to investigate tumor microstructures with non-invasive diffusion-weighted MRI. Heterogeneous tumors contain different subregions, called habitats. We are interested in developing multispectral analysis algorithms using different MR sequences to delineate various habitats including hypercellualr tumour, necrosis, proteinaceous fluid etc. In addition, we seek to further understand the tumour microenvionment by modeling cellular geometries and mapping tumour cell size and cellulariy in patients using advanced diffusion MRI sequences, such as oscillating gradient spin echo sequences.
