METHODS: 84 Patients (68 ± 8 years; range, 33-79 years) who had undergone CEUS were included. All the images were offline analyzed. Parameters (maximum intensity (IMAX), rise time (RT), time to peak (TTP) and mean transit time (mTT)) were recorded and compared with PSA level, Gleason score, clinical stages and PCa risk.
RESULTS: Age was correlated significantly with PCa risk. RT and mTT of outer gland were associated with PCa risk. No significant correlation was found between PSA and CEUS enhancement parameters. Furthermore, with the exception of IMAX of inner gland and IMAX of outer gland, there were no significant differences of enhancement parameters in Gleason score groups and clinical stages groups.
CONCLUSION: The enhancement parameters of PCa at CEUS may be used to predict PCa risk. And it is helpful for the choice of therapeutic options.
