3D-MT-TOF MRA在粥样硬化性动脉瘤中的诊断价值

摘要

ObjectiveTo discuss the diagnosis value of 3D-MT-TOF MRA in atherosclerotic aneurysm.Methonds To 45 patients doubt suffer from intracranial atherosclerotic were examined 3D-MT-TOF MRA,using MT technology.according to blood vessels by maximum density projection and volumetric reconstruction.Results In 45 cases imaging of MRA,32cases diagnosis atherosclerotic,9 cases with aneurysm,among them,7 cystic aneurysm,4 spindle aneurysm(2 cases both the aneurysm);4 cases aneurysm occur in the internal carotid artery,2 cases aneurysm occur in the middle cerebral artery,3 cases aneurysm occur in the posterior cerebral artery,1 case aneurysm occur in the vertebral artery. Conclusion 3D-MT-TOF MRA to reconstruction the intracranial arterial satisfied,can clearly rendering the atherosclerotic narrow and aneurysm .provided reliable basis to the clinical,also can be used as a preferred method of screening.%目的：探讨3D-MT-TOF MRA在粥样硬化性动脉瘤中的诊断价值。方法对45例怀疑颅内动脉粥样硬化患者行MR检查，采用MT技术、最大密度投影及容积重建显示血管。结果45例患者MRA成像，其中32例诊断动脉粥样硬化，9例伴动脉瘤（7例单个囊性动脉瘤，2例囊性、梭形动脉瘤各1个，共11个动脉瘤）；4例（个）动脉瘤发生于颈内动脉，2例（个）发生于大脑中动脉，3例（个）发生于大脑后动脉瘤，2例（个）发生于椎动脉。结论3D-MT-TOF MRA对颅内动脉血管显示满意，对动脉粥样硬化性狭窄、动脉瘤显示清晰，可为临床提供可靠的诊疗依据，并可作为病例筛查及随访的首选方法。
