Abstract

Objectives: Compare the reliability and diagnostic performance of prostate cancer of biparametric MRI and multiparametric MRI using the PIRADs 2.1. Methods and subject:  82 patients suspected prostate cancer were underwent multiparametric MRI 3.0T including T2W, DWI, DCE and had histopathological results through biopsy. Lesions were graded 1 to 5 for T2W and DWI sequences, graded negative or positive for DCE according to the PIRADs 2.1, total PIRADs scores for 2 sequences (T2W and DWI), and total PIRADs for 3 sequences (T2W, DWI, DCE). The standard used for comparison is the 12 points biopsy pathology results. Results: Among 82 patients with 328 lesions, there were 159 tumoral lesions and 169 benign lesions. Sensitivity, specificity, positive predictive value, negative predictive value of biparametric MRI were 86.8%; 96,4%; 95,8% 88,6%, respectively. These values of multiparametric MRI were 88.7%; 86,4%; 95,9%; 90%, respectively. Conclusion: When using the PIRADs 2.1, the diagnostic value of biparametric MRI can be considered equivalent to multiparametric MRI in identifying prostate cancer. DCE should be used as an optional sequence, indicated additionally on certain cases.
