摘要:
:目的评价斜矢状位T1W(QIR-FSE)黑血序列测量颈动脉分叉角的可行性及测量方法。方法23例行颈动脉MRI扫描患
者,分为正常组及斑块组,分别使用2D-TOF及斜矢状位TIW黑血序列测量颈动脉分叉角,3月后重复测量。分析两种序列前后
两次测量的重复性,评价两种序列测量结果一致性。采用不同点连线以确定测量方法。结果排除不符合标准病例后共有20例
进行分析,两种序列两次测量结果均有较好的重复性。两种序列测量结果配对,无论是正常组还是斑块组,t检验显示两种序列
测量结果有显著统计学差异(P<0.05),但是对于两侧颈动脉分叉角比值,两种序列比较无统计学意义(P>0.05)。正常组及斑块
组两侧颈动脉角度比值方差分析结果显示,斜矢状位T1W序列4组不同点连线夹角的4组数据间无差异。结论采用我们测量
颈动脉分叉角的方法,斜矢状位T1W(QIR-FSE)序列可用来测量颈动脉分叉角。
Abstract:
Objective To evaluate the feasibility by oblique sagittal T1-weighted (QIR-FSE) black-blood sequence for
measurement of the carotid bifurcation angle. Methods Twenty-three patients undergoing carotid magnetic resonance imaging
(MRI) were divided in normal group and plaque group. Carotid bifurcation angle was measured by both 2D-TOF and oblique
sagittal T1W (QIR-FSE) black-blood sequence, and the measurement was repeated after 3 months to evaluate the
reproducibility. The measurement results using 2D-TOF and oblique sagittal T1W (QIR-FSE) black-blood sequence were
compared to assess the consistency of the two sequences. Four different angles of each carotid artery were measured from
different locations on oblique sagittal T1W. The ratio of the bilateral carotid bifurcation angle (Right/Left) was compared.
Results Ten patients in each group were enrolled after excluding 3 patients. Strong correlations were found between the
results of the first and the second measurements for both 2D-TOF and oblique sagittal T1W sequences. No significant
difference was found between the two sequences in the ratio of bilateral carotid bifurcation angle (right/left), nor in the 4
angles from different locations. Conclusion Oblique sagittal T1-weighted (QIR-FSE) black-blood sequence can be used to
measure the carotid bifurcation angle.
