摘　　要：目的基于超高分辨率CT(ultra-high resolution CT,U-HRCT)对筛前动脉管进行解剖学研究,提高临床对筛前动脉管的认识。方法收集10%福尔马林溶液固定的成人头颅标本9个(眼眶18侧),应用U-HRCT和常规多层螺旋CT(multisliecs helieal CT,MSCT)采集眼眶CT图像。将筛前动脉管分为水平段、上斜段、下斜段,分别观察各段显示率,由两位放射科医师对各段的显示情况进行主观评价,并在U-HRCT上测量筛前动脉管各段的管径。结果U-HRCT与MSCT对筛前动脉管水平段及上斜段显示率无显著性差异(P>0.05),U-HRCT对筛前动脉管下斜段的显示率高于MSCT(P<0.05)。两位医师主观评价结果无显著性差异且一致性较好。U-HRCT对筛前动脉管各段的主观评分分别是10.00分(9.75分,10.00分)、2.00分(2.00分,3.00分)和8.00分(6.00分,10.00分)。MSCT对筛前动脉管各段的主观评分分别是7.00分(5.75分,8.00分)、2.00分(2.00分,2.00分)和2.00分(2.00分,4.00分),其中U-HRCT组对于筛前动脉管水平段及下斜段的总评分明显高于MSCT组(P<0.05)。筛前动脉管水平段的前后径为(0.92±0.12)mm,上下径是(1.04±0.22)mm;上斜段的前后径为(0.47±0.08)mm,左右径为(0.50±0.06)mm;下斜段的前后径为(0.66±0.11)mm,左右径为(0.72±0.20)mm。结论U-HRCT对筛前动脉管各段的显示能力优于MSCT,对筛前动脉管的解剖学认识提供帮助,可应用于临床术前评价筛前动脉管的全程。OBJECTIVE To study the anatomic characteristics of the anterior ethmoidal canal(AEC)based on 0.1 mm ultra-high resolution CT.METHODS Nine cadavers(18 side orbits)fixed in 10%buffered formalin were enrolled and underwent U-HRCT and MSCT.Divided AEC into horizontal,superior oblique,and inferior oblique segments and observed the displaying rate of each section.Subjective evaluation of display situation was performed by two experienced radiologists independently.The diameter of each AEC segment was measured.RESULTS No significant difference was found in the display rate of the horizontal and superior oblique segments between U-HRCT and MSCT groups(P>0.05),the display rate of inferior oblique segment of U-HRCT group was significantly higher than MSCT group(P<0.05).There was no significant difference in the objective evaluation results between two evaluators and consistency was strong.Subjective scores of each segment of AEC in U-HRCT group were 10.00 points(9.75 points,10.00 points),2.00 points(2.00 points,3.00 points)and 8.00 points(6.00 points,10.00 points),in MSCT group were7.00 points(5.75 points,8.00 points),2.00 points(2.00 points,2.00 points)and 2.00 points(2.00 points,4.00 points).Subjective scores of horizontal and inferior oblique segments of AEC in U-HRCT were higher than MSCT(P<0.05).The anteroposterior diameter of the horizontal section of AEC is(0.92±0.12)mm,the axial diameter is(1.04±0.22)mm.The anteroposterior diameter of the inferior oblique segment is(0.47±0.08)mm,and the transverse diameter is(0.50±0.06)mm.The anteroposterior diameter of the superior oblique segments is(0.66±0.11)mm,and the transverse diameter is(0.72±0.20)mm.CONCLUSION U-HRCT is better to evaluate AEC than MSCT.It could be used to help to study the anatomic characteristics of AEC before surgery to avoid complications.
