Diffusion Tensor Imaging (DTI) has been applied in prostate cancer diagnosis. It has been well accepted that water apparent diffusion coefficient (ADC) has a lower value in tumours than in healthy prostatic tissue, while fractional anisotropy (FA) has been reported to be higher, lower, and unchanged. Histology slices were registered with in-vivo and ex-vivo DTI images, and average values of ADC and FA were calculated for certain regions of interest. No significant differences in FA between normal peripheral zone and prostatic carcinoma were found suggesting that FA is not likely to contribute to diagnostic capabilities of DTI in prostate cancer.
