Abstract:
Objective ToquantitativelystudythecorrelationbetweenT2mappingvalueofthesupraspinatuswithfattydegenerationand supraspinatustendontear.Methods From MarchtoSeptemberin2016,patientswithsupraspinatustendontearinourhospitalwere enrolled.TheT2mappingvalueofthesupraspinatuswasmeasured.Accordingtothesupraspinatustendontearclassification,patients weredividedintogroupA,BandC.ThecorrelationwasanalyzedbetweenT2mappingvalueandsupraspinatustendontear.Results 45patientswereenrolled,including30malesand15females,aged15－85years,withanaverageageof(45.4±16.6)years.Among the45shoulderjoints,12jointswereingroupA withnotendontear,14jointswereingroupBwithincompletetomoderatetear,and 19jointswereingroupCwithmosttofulllayertear.TheT2mappingvaluesofsupraspinatusingroupA,BandCwere46.0±7.0,51.5± 10.6and65.0±8.4,respectively.TheT2mappingvalueincreased withtheseverityofthesupraspinatustendontear (P＜0.001), whichwaspositivelycorrelated.Conclusion ThemeasurementofT2mappingisareliable methodforquantitativelyevaluatingthe fattydegenerationinthesupraspinatus.ThatthehigherT2mappingvalue,thehigherfatcontentinthesupraspinatusmuscle,suggests thetearofsupraspinatustendonismoreserious.T2mappingisanotheroptionalmethodforclinicaldiagnosisandprognosisevaluation oftherotatorcufftear.
