ABSTRACT
Objective ToexplorethevalueofMRIinthediagnosisofcoronaryarteryandmyocardiallesionsinchildrenwithKawasaki disease.Methods CardiacMRIof38patientswithKawasakidiseasewereretrospectivelyanalyzed.MRIsequencesincludedthree dimensionalsteady-statefreeprecession (3D-SSFP)coronaryarteryimaging,first-passperfusiontoassessmyocardialischemia,late gadolinium-enhancedmagneticresonanceimaging(LGE-MRI)toassessmyocardialhistologyfeatures,and2D-SSFPcinesequenceto evaluatecardiacfunction.Themaximumdiametersofcoronaryaneurysmsmeasuredin3D-SSFPwerecomparedwiththosemeasured inechocardiography(ECHO)byBland-Altmananalysis.Results Amongthe38cases,therewere28cases(73.7%)withaneurysmal dilatationinrightcoronaryartery(RCA)orleftcoronaryartery (LCA).Thehighestincidenceofaneurysmaldilatationwasinleft anteriordescendingbranch (LAD)in23cases,andfollowedbyRCAin19cases.ThemaximumdiameterofRCAaneurysm (7.66± 2.10)mm washigherthanthatofLADaneurysm (6.11±1.96)mm withP<0.05.Myocardialfirst-passperfusionin5casesshowed leftventricularandventricularseptumsubendocardialischemia,LGE-MRIin5casesshowedmyocardialdelayedenhancementinleft ventricularfreewallandventricularseptum,andtheleftventricularejectionfractionsin4caseswerelessthan50%,withanaverage of(34.0±15.9)%.3D-SSFPandECHOshowedgoodconsistencyinthemaximaldiametermeasurementofRCAandLADaneurysm. Conclusion TheimagingfeaturesindifferentsequencesofMRIcanbeusedtocomprehensivelyevaluatethecoronaryarteryand myocardialhistologicalcharacteristicsofKawasakidisease,includingcoronaryaneurysms,thrombosis,myocardialfibrosisandchanges ofventricularfunction.
