DCE	Grading standards
DCE negative	(I) No reinforcement in the early stage
	(II) Enhanced diffusion, with no corresponding focal expression on TWI or DWI
	(III) Corresponding lesions on DWI showed features of prostatic hyperplasia with focal enhancement. Negative DCE is defined as having one of the three
DCE positive	Focal, prior to or concurrent with the enhancement of adjacent normal prostate tissue, consistent with the corresponding suspicious lesions of TWI and DWI
