螺旋CT对双侧横窦管径的研究分析

目的 探讨螺旋CT静脉期成像在测量双侧横窦管径中的价值.方法 回顾性分析在本院行脑血管增强扫描检查的200例窦汇区血管影像,常规使用CT原始图、减影CT静脉成像(CTV)的容积再现(VR)及最大密度投影(MIP)的方法,观察窦汇区血管解剖结构不同表现,并进行优势横窦判定及分型(Ⅰ~Ⅵ型);并在CT原始图上进行双侧横窦管径的测量,按性别分2组,按年龄分4组(20~30岁、30~40岁、40~50岁、50~60岁)进行统计学分析.结果 不同性别组间,右侧横窦管径男性大于女性,差异有统计学意义(P<0.05);左侧横窦管径差异无统计学意义(P>0.05);各年龄组间,双侧横窦管径差异均无统计学意义(P>0.05).结论 螺旋CT能够较好地评价横窦的管径,为临床疾病提供相关解剖学基础,具有重要意义.

Study of bilateral transverse sinus diameter with spiral CT

Objective To explore the value of spiral CT in venous phase in measuring the diameter of bilateral transverse sinus.Methods The CT vascular imaging findings of 200 cases at torcular herophili area in our hospital were analyzed retrospectively.The resource images, volume rendering (VR) and maximum intensity projection (MIP) were performed to observe the presentation of vascular anatomy in the torcular herophili area, and to determine the dominant transverse sinus and types of torcular herophili (typeⅠ-Ⅵ).The diameters of bilateral transverse sinus were measured by original CT images.Two groups were categorized according to the genders, and four ones (20-30 years, 30-40 years, 40-50 years and 50-60 years) according to the age.Results Between different genders, there was significant difference in right transverse diameter (P<0.05), and there was no significant difference in left transverse diameter (P>0.05).There was no significant difference among four age groups in bilateral transverse diameter (P>0.05).Conclusion Spiral CT is helpful for the evaluation of the diameter of bilateral transverse sinus.These findings can provide anatomical basis for clinical disease with significant implication.
