Abstract Objective: To study the early diagnostic value of 3.0T MR in prostatic cancer. Methods: To analyse the MR features in 12 cases of early prostatic cancer confirmed by surgery pathology, and needle biopsy. Conventional sequence, DWI and dynamic contrast enhanced scanning were performed. Results: The lesions of the 12 early prostatic cancer cases were all located in the capsule, T2WI fat suppression showed abnormal low signal within the peripheral zone in 8 cases, the other 4 cases showed slightly higher signal in the central zone, DWI sequence in 10 cases showed high signal, 2 cases showed iso-intense signals. LAVA multi-phase dynamic contrast-enhanced scans showed the lesions were obviously enhanced in the arterial phase, low signal in the balance period, in 8 cases 3 cases were continually and progressively enhanced; one case was not obviously enhanced in the arterial phase. Conclusion: 3.0T MR conventional T2WI sequences, DWI and dynamic contrast-enhanced imaging have characteristic MR features and important diagnostic value for early prostatic cancer.
