This work explores the diffusion weighted (DW) MR signal of cancer cell lines with a selection of multi-compartment diffusion models, adapting a method for diffusion model identification in brain tissue . Characterisation of colorectal cancer cells (CRC) can improve the response of the cells to treatment. Most previous cancer cell classification studies involve invasive histological methods that alter the state of the sample. This study uses DW-MRI to quantitatively characterise CRC cell lines in vivo based on their microstructure.
