Abstract:
Objective To analyze the qualitative efficacy of MRI multi-sequence scanning combined with fPSA/tPSA in benign and malignant prostate lesions.Methods A retrospective analysis was conducted on the clinical data of 118 patients with suspected prostate cancer who visited Hebei Provincial First Veterans Hospital from January 2021 to November 2023.All the patients underwent DWI and DCE-MRI examinations.They were divided into the benign group(n=39)and the malignant group(n=39)based on the pathological results of partial prostatectomy or ultrasound-guided prostate biopsy.The DWI parameters,DCE-MRI parameters,PI-RADS scores,and fPSA/tPSA of the two groups were compared to analyze the factors influencing benign and malignant prostate lesions.ROC curves were drawn to analyze the diagnostic value of each index for benign and malignant prostate lesions.Results Among 118 suspected prostate cancer patients,118 lesions were detected through biopsy at our hospital or initial diagnosis at Hebei Provincial First Veterans Hospital followed by surgical and biopsy pathological examinations at external medical institutions.Of these lesions,79(66.95%)were malignant and 39(33.05%)were benign;the Rmax and SImax of the malignant group were higher than those of the benign group,and the Tmax and ADC values were lower than those of the benign group(P<0.05);the PI-RADS scores were higher than the benign group,and fPSA/tPSA was lower than the benign group(P<0.05);Multivariate logistic regression analysis revealed that Rmax[OR:1.374(95%CI:1.211～1.560)],SImax[OR:6.849(95%CI:2.573～18.230)],and PI-RADS score[OR:4.689(95%CI:2.646～8.309)]were the risk factors for malignant prostate lesions(P<0.05),while Tmax[OR:0.906(95%CI:0.873～0.941)],ADC value[OR:0.930(95%CI:0.905～0.955)],and fPSA/tPSA[OR:0.859(95%CI:0.812～0.908)]were protective factors(P<0.05);the ROC curve revealed that the AUC(95%CI)of Rmax,SImax,Tmax,ADC value,fPSA/tPSA,and PI-RADS score for the diagnosis of benign and malignant prostate lesions were 0.827(0.747～0.906),0.752(0.660～0.844),0.851(0.773～0.930),0.845(0.765～0.925),0.813(0.722～0.905),0.844(0.768～0.920),and 0.940(0.883～0.997).Conclusion DCE-MRI and DWI combined with PI-RADS score and fPSA/tPSA can improve the qualitative diagnostic accuracy of malignant prostate lesions,and provide reference for clinical identification of benign and malignant lesions.
