A novel, hybrid MR imaging method was implemented for prostate cancer detection. The proposed hybrid imaging acquires diffusion weighted MRI (DWI) data at three echo times (TEs), and allows calculation of ADC and T2 as functions of TE and diffusion weighting factor (b-value), respectively. Preliminary results showed that both ADC and T2 calculated from the hybrid imaging data can help differentiate normal tissue regions and cancer foci. ADC at higher TE showed better differentiation than ADC at lower TE. The two dimensional 1/T2 map improved separation of cancer and normal voxels relative to a 1D comparison.
