Abstract:
Objective Toinvestigate MRIIVIM quantitativeassessmentoftheplacentalperfusioncanbeusedtodifferentiate womenwithandwithoutplacentaaccretaintheirthirdtrimester.Methods Thestudypopulationincluded17patientswithplacenta accreta,29patientswithplacentaincretaand16patientswithoutplacentaaccreta.Allwomenunderwentan MRIexaminationincluding anIVIMsequence.Theperfusionfraction(f),pseudodiffusioncoefficient(D?)andstandarddiffusioncoefficient(D)werecalculated. Results Womenwithplacentaaccretaandincretahadasmallerplacentalperfusionfraction (P＜0.05)thanpatientswithoutplacenta accreta,theplacentalperfusionfractiondidn’tdifferedbetweenplacentaaccretaandincreta(P＞0.05).DifferencesofDandD?between thethreegroupswerenotsignificant(P＞0.05).Conclusion Placentaaccretaandincretadifferinplacentalperfusionfractionfrom womenwithoutthedisease.Theperfusionfractioncanbeusedasafeasibleindextoevaluateplacentaperfusion.
