| 摘 要： | 目的评价3.0T三维高时间分辨率对比增强磁共振血管造影(time-resolved contrast-enhanced three-di-mensional magnetic resonance angiography,TR3DCE-MRA)对四肢血管瘤临床应用的可行性和价值。资料与方法21例四肢血管瘤患者,全部使用3.0T全身磁共振(Magnetom Trio,Siemens Medical Solutions,Erlangen,Germa-ny)扫描,采用高压注射器(Medrad,Spectris)将单倍剂量(0.1mmol/kg体重)对比剂(马根维显)经肘静脉以2.5ml/s流率注射。TRCE-MRA采用快速小角度激发梯度回波序列(fast low-angle shot gradient-echo,FLASH),均采用冠状位扫描,图像全部传送至工作站采用最大密度投影(MIP)进行后处理,测量其供血动脉和引流静脉的信噪比(signal-to-noise ratio,SNR)和对比噪声比(contrast-to-noise ratio,CNR),并由两位影像专家评价图像质量和诊断结果。结果所有图像均能满足诊...

| Abstract: | Objective To discuss the feasibility and value of time resolved contrast enhanced three-dimensional magnetic resonance angiography (TR3DCEMRA) in the diagnosis of limb's hemangioma.Materials and Methods 21 patients of limb's hemangioma underwent time-resolved 3D CEMRA on a 3T whole-body scanner. Standard-dose (0.1 mmol/kg) contrast material was injected with a flow rate of 2.5 ml/s via a cubital vein with a power injector. Time-resolved 3D CEMRA was performed using a coronal FLASH sequence. The images were ... |
