Abstract:
Objective Toinvestigatethediagnosticvalueofhigh-resolutionmagneticresonanceimaging (HR-MRI)andCTAin intracranialarterialwallplaques.Methods 27patientswithbothHR-MRIandCTAdatawereenrolled.TheresultsofHR-MRIand CTAdiagnosisonatheroscleroticplaquestypeswerecomparedandanalyzed.Results (1)In59segmentsofbloodvesselswithlesions, 120atheroscleroticplaquesorstenoseswereidentifiedbyCTAand108atheroscleroticplaquesbyHR-MRI.Total122plaqueswere identifiedbybothtechniques,and78plaqueswereconsistentonbothtechniques,including43calcifiedplaques,14mixedplaquesand 21non-calcifiedplaques.ThediagnosisresultsofHR-MRIandCTA werenotconsistentin44plaques:27stenosesidentifiedbyCTA wereshownasnon-calcifiedplaqueson HR-MRI;14calcifiedplaquesidentifiedbyCTA weredifficulttobejudgedon HR-MRI;2 non-calcifiedplaquesidentifiedbyHR-MRIwerepresentasnormalonCTA;onemixedplaqueidentifiedbyCTA wasdiagnosedas non-calcifiedplaquebyHR-MRI.(2)Thereweredifferencesinshowingplaquepatternsbetweenthetwomethods(P＜0.001);CTA hadanadvantageinshowingcalcifiedplaques,whileHR-MRIhadanadvantageovernon-calcifiedplaques(adjustedstandardizedresidual wasgreaterthanthree).Conclusion 3.0T HR-MRIhasagoodabilitytodetectnon-calcifiedplaques,whileCTA hasauniqueadvantage todetectcalcifiedplaques.Twotechniquescomplementingeachothercanimprovethedetectionofatheroscleroticplaques.
