Abstract
AbstractObjective:To explore the diagnostic value of quantitative analysis parameters of DCE-MRI in prostate cancer diagnosis, and to evaluate the correlation between Ktrans, Kep and Ve and Gleason scores. Materials and Methods:Forty-three prostate diseases patients pathologically proved underwent conventional MRI and DCE-MRI examinations, including 27 patients with prostate cancer and 16 with prostate hyperplasia. The variations of the value of Ktrans, Kep and Ve between the prostate cancer and hyperplastic tissues were measured and compared, and the correlations between Ktrans, Kep and Ve and Gleason scores were studied.Results:The Ktrans, Kep and Ve values of cancerous area were (0.312±0.085) min-1, (0.818±0.098) min-1 and (0.379±0.031), while, for hyperplastic area were (0.213±0.046) min-1, (0.537±0.076) min-1 and (0.324±0.034). The values of Ktrans, Kep, Ve were signiifcantly higher in prostate cancer than in hyperplastic tissues; and Ktrans, Kep, Ve values were not relevant with Gleason score.Conclusion:DCE-MRI quantitative analysis plays a signiifcant role in prostate cancer diagnosis, and may help in differential diagnosis of prostate tumors. Ktrans, Kep and Ve values were not relevant with Gleason score.关键词
