ABSTRACT
Objective ToexplorethevalueofMR DKIinevaluationofmicrostructuredamageincervicalspinalcordinjury(CSCI) Methods 32casesofCSCIpatientsconfirmedbyclinicalexaminationand20casesofhealthycontrolgroupwereinvestigatedbyconventional MRIandDKIexamination.AccordingtoT2WIsignal,theinjurygroupweredividedintoA,Bgroup,Agroupofhighsignalgroup(n=14)andBgroupofnegativegroup (n=18).A,BgroupsandcontrolgroupweremeasuredbyFA,meandiffusivity(MD)and mean kurtosis(MK)valuesatdifferenttimes (acute,4 weeksafterinjury,2to3 monthsafterinjury)andthedata wereanalyzedby SPSS17.0statisticalsoftware.TheROCcurvewasusedtoevaluatetheabilityofdifferentparametersindiagnosingCSCI.Results In A,BgroupsFAvaluesdecreasedearlyandincreasedgradually,butwerealwayslowerthanthecontrolgroup,andthedifferencewas statisticallysignificant(P<0.001).InAgroup MDvalueincreasedearlyanddecreasedgradually,butwashigherthanthecontrol group (P<0.001).InAgroup MKvaluedecreasedearlyandincreasedsignificantly(P<0.001).InBgroup MDvalueincreasedand MKvaluedecreasedintheacutephase(P<0.001),lateron MDand MKvaluesgraduallytendtothecontrolgroup,thedifference wasnotstatisticallysignificant(P>0.05).Conclusion DKIcannoninvasivelyreflectthemicroGdamageofCSCI,whichcannotbedisplayed byconventionalMRIfortheearlydetectionofspinalcordabnormalities.TheFAvalueisofhighdiagnosticvalue.
