| 目的 探讨头颅MSCT血管造影(MSCTA)对颞浅动脉(STA)的显示能力及临床应用价值。方法 对88例头颅MSCTA原始图像数据分别进行遮盖容积重建(SVR)、MIP及CPR,观察STA是否有明显分支,记录血管杈的位置,测量STA主干、额支及顶支的管径,并评价3种重建图像的质量。结果 88例中,80例左侧STA(LSTA)及77例右侧STA(RSTA)可见明显额支及顶支,血管杈均位于颧弓上或颧弓水平;8例LSTA及11例RSTA未见明显额支或顶支。LSTA主干、额支及顶支直径分别为(2.26±0.39)mm、(1.71±0.25)mm及(1.74±0.26)mm;RSTA主干、额支及顶支直径分别为(2.32±0.46)mm、(1.81±0.25)mm及(1.81±0.19)mm。SVR与MIP图像质量评分差异无统计学意义(Z=-2.11,P>0.05),且均高于CPR(Z=-7.94、-7.48,P均<0.01)。2名诊断医师对SVR及MIP图像质量评分的一致性均较好(Kappa=0.92、0.85),对CPR图像质量评分的一致性一般(Kappa=0.51)。结论 头颅MSCTA可清晰、准确地显示STA的解剖结构。 |

| Objective To assess the ability of head MSCT angiography (MSCTA) in displaying superficial temporal artery (STA) and its clinical value. Methods The primeval MSCTA imaging data of head in 88 cases were processed with multiple post-processing techniques, including shaded volume rendering (SVR), MIP and CPR. Whether there were distinct branches in STA and the position of bifurcation were observed and recorded. The diameters of main STA, frontal branch and parietal branch were measured. And the image quality of the three reconstruction methods were evaluated. Results There were distinct branches of left STA (LSTA) in 80 cases and of right STA (RSTA) in 77 cases. All of STA bifurcated at or over the superior margin of the zygomatic arch. No frontal branch or parietal branch was found at LSTA in 8 cases and at RSTA in 11 cases. The diameter of main LSTA, frontal branch and parietal branch was (2.26±0.39)mm, (1.71±0.25)mm and (1.74±0.26)mm, respectively. And the diameter of main RSTA, frontal branch and parietal branch was (2.32±0.46)mm, (1.81±0.25)mm and(1.81±0.19)mm, respectively. No statistical difference of image quality score was found between SVR and MIP (Z=-2.11, P>0.05). Both of the image quality scores of SVR and MIP were higher than CPR (Z=-7.94, -7.48, both P<0.01). The consistency of image quality scores between two diagnosticians for SVR and MIP were better (Kappa=0.92、0.85), while the consistency of CPR was common (Kappa=0.51). Conclusion Head MSCTA can clearly visualize the anatomic structure of STA. |
