ThevalueofGd-EOB-DTPA-enhanced MRIindiagnosisofhepatocellularcarcinoma / 实用放射学杂志

ABSTRACT

Objective ToexplorethediagnosticvalueofenhancedCTandGd-EOB-DTPA-enhanced MRIinthedetectionofhepatocellular carcinoma (HCC).Methods 41patientswith52HCCsunderwentenhancedCTandGd-EOB-DTPA-enhancedMRIrespectively.The imagingmanifestationswereanalyzed,andthelesionsweregrouped.Theimagingdiagnositicresultswerecomparedwiththepathologicalresults, andtheefficacyofthetwomodalitieswasevaluatedusingtheaccuracyindex.Results Ofthetotal52HCCs,42lesionswereidentifiedexactlyby enhancedCT,and51byGd-EOB-DTPA-enhancedMRI.Foralllesions,includingsmalllesions(≤2cm),theaccuracyratioofGd-EOB-DTPA-enhancedMRIwashigherthanthatofenhancedCT withastatisticallysignificantdifference(P<0.05),however,therewasnosignificant differenceforthelesionsbiggerthan2cm (P>0.05).Conclusion EnhancedCTislimitedindiagnosisoftheHCCssmallerthanor equalto2cm.ThediagnosticefficacyofGd-EOB-DTPA-enhanced MRIishigherthanthatofenhancedCT,anditcansignificantly improvethediagnosisofsmallHCC.
