Analysis of the diagnostic value of BP-MRI combined with prostate specific antigen markers for prostate cancer
Objective To explore the diagnostic value of biparametric magnetic resonance imaging(BP-MRI)combined with prostate specific antigen(PSA)markers for prostate cancer.Methods 86 patients with suspected prostate cancer were selected as the study subjects,and all underwent BP-MRI and PSA examination respectively.The pathological diagnosis results were used as the gold standard,and the results of BP-MRI and PSA alone and in combination were recorded for the diagnosis of prostate cancer,and the diagnostic efficacy of the three examination methods was compared;the PSA parameters[free prostate-specific antigen(f-PSA),total prostate-specific antigen(t-PSA)]were compared between patients with prostate cancer and those with prostate hyperplasia.Results 86 suspected prostate cancer patients were diagnosed by pathology,of which 45 cases(52.33%)were diagnosed with prostate cancer,and 41 cases(47.67%)were diagnosed with prostate hyperplasia.BP-MRI alone was positive in 38 cases and negative in 48 cases;PSA parameters alone was positive in 40 cases and negative in 46 cases;and combined examination was positive in 46 cases and negative in 40 cases.The diagnostic sensitivity and accuracy of the combined examination were 97.78%and 96.51%,which were significantly higher than 80.00%and 87.21%of BP-MRI examination alone,and 82.22%and 87.21%of PSA parameters examination alone(P<0.05).The f-PSA of prostate cancer patients was(5.81±1.96)ng/ml and t-PSA was(38.52±5.65)ng/ml,which were significantly higher than(1.85±0.31)and(8.22±1.68)ng/ml of prostate hyperplasia patients(P<0.05).Conclusion The clinical diagnosis of prostate cancer can adopt the combination of BP-MRI and PSA parameters,which has higher accuracy compared to a single examination,and can provide reliable imaging and indicator support for clinical practice.It is worth promoting.
