Validation of the feasibility of TCIR (two compartment inversion recovery) contrast agent-free approach for prostate cancer detection by comparison with the standard T2w, DCE- and DWI-sequences. Using the TCIR technique it was possible to generate good quality high-resolution maps of the fractional blood volume in the prostate without using a contrast agent. TCIR has a high potential for prostate cancer detection because of its high spatial resolution and sensitivity, first of all in patients, which cannot be examined using contrast media.
