简介:摘要目的探究在头颈部CTA中应用低剂量CT扫描的效果.方法于2013年3月至2015年3月,择取可能存在动脉血管性病变的60例患者,将其随机分为实验组与参照组,各30例.参照组患者予以常规剂量CT扫描,实验组予以低剂量CT扫描,对图像质量以及诊断情况予以比较.结果实验组图像质量的优良率为93.33%,参照组图像质量的优良率为100.00%(P>0.05).实验组的辐射剂量显著小于参照组(P<0.05),而两组的虹吸段平均CT值不存在显著差异(P>0.05).结论低剂量CT扫描可广泛应用于头颈部CTA检查,辐射小,图像质量高,诊断准确性高.关键词低剂量CT扫描技术;头颈部CTA;应用价值LowGdoseCTscanningtechnologyValuationoftheheadandneckCTALiangZhimei(DepartmentofRadiology,RuikangHospitalAffiliatedtoGuangxiUniGversityofChineseMedical530011)AbstractObjectiveToexploretheapplicationoftheheadandneckCTAeffectoflowGdoseCTscans.MethodsFromMarch2013toMarch2015,60casespossiblearterydiseasespatientswereselected,wererandomlydividedintoexperimentalgroupandthereferencegroup,30caseseach.ReferringpatientstobebelowGdoseCTscanningroutine-doseCTscan,theexperimentalgroup,tobecomparingtheimagequalityanddiagnosticconditions.ResultsTheexperimentalgroup??sexcellentimagequality93.33%ofthereferencegroupofimagequalityexcellentratereached100.00%(P>0.05).Radiationdoseintheexperimentalgroupwassignificantlylowerthanthereferencegroup(P<0.05).TheaveragevaluesofthetwogroupssiphonCTnosignificantdifference(P>0.05).ConclusionLowGdoseCKTeyscwaonrdcsanbewidelyusedinheadandneckCTAexamination,theradiationissmall,theimagequalityishigh,thediagnosticaccuracyishigh.low-doseCTscanningtechnology;headandneckCTA;Value中图分类号R816文献标识码B文章编号1008-6315(2015)12-1038-02__
