多层螺旋CT口服低张小肠造影的临床应用研究 Title:ClinicalApplicationofMulti-layerSpiralCTinOralLow-DensitySmallIntestineImaging Abstract: Objective:Toexploretheclinicalapplicationofmulti-layerspiralCTinorallow-densitysmallintestineimagingforthediagnosisofsmallintestinediseases. Methods:Atotalof200patientssuspectedofsmallintestineabnormalitieswereenrolledandunderwentmulti-layerspiralCTfororallow-densitysmallintestineimaging.Theimagingresultswereassessedbyexperiencedradiologists,andthediagnosticaccuracyandfeasibilityofthismethodwereevaluated. Results:Themulti-layerspiralCTorallow-densitysmallintestineimagingshowedclearimagesofthesmallintestinewithexcellenttemporalandspatialresolution.Thelesions,includingtumors,strictures,andabnormalmucosalpatterns,wereaccuratelyidentified,andthedetectionrateofsmallintestinediseaseswassignificantlyimprovedcomparedtoconventionalimagingmethods.TheaverageeffectivedoseofradiationexposureinthisstudywasX.Thepatientstoleratedtheprocedurewellwithminimaldiscomfortreported.
