ApplicationofmultiGparameterMRIinthediagnosisofprostatecancer / 实用放射学杂志

ABSTRACT

Objective Toexploretheapplicationvalueofmulti-parametermagneticresonanceimaging(MP-MRI)inthediagnosis ofprostatecancer(PCa).Methods Theclinicaldataof50patientssuspectedasPCaandadmittedbetweenJanuary2017andJanuary 2018wereretrospectivelyanalyzed.Thepathologicalexaminationwasusedasthegoldstandard,andallpatientsunderwentMP-MRI. Theapplicationvalues(sensitivity,specificity,accuracy,positivepredictivevalue,andnegativepredictivevalue)ofMP-MRIwereevaluatedin thediagnosisofPCa.Results Amongsingleexaminationofeachsequence,thesensitivity,accuracyandnegativepredictivevalueof DWIwerehigher,whilethespecificityandpositivepredictivevalueofT2WIwerehigher.ThesensitivityofMP-MRIcombinationwas assameasthatofDWI,butthespecificity,accuracy,positivepredictivevalueandnegativepredictivevaluewerehigherthanthoseof anysingleexamination.PI-RADSscoresofthePCawerehigherthanthoseofthebenignprostatichyperplasiainT2WI,DWI,DCE-MRI and MP-MRIcombination(P＜0.05).TheADCvalueofthePCawaslowerthanthatofthebenignprostatichyperplasia(P＜0.05). Conclusion MP-MRIcombinationcanobtain moreeffectiveinformationforprostatediseases,andhashigherspecificity,accuracy, positivepredictivevalueandnegativepredictivevalueindiagnosingPCa.
