腹腔神经节的多层螺旋CT表现

Multi-Detector CT Findings of Celiac Ganglia

目的探讨腹腔神经节多层螺旋CT(MDCT)的表现。资料与方法回顾分析133例上腹部CT平扫和增强扫描无异常患者的CT资料,记录和测量腹腔神经节的位置、形态及大小。结果左侧腹腔神经节124例显示,9例显示不清;右侧115例显示,18例显示不清,两侧显示率的差异无统计学意义(左侧,93.2%;右侧,86.5%;χ2=3.339,P=0.068)。双侧腹腔神经节位于腹腔干及肠系膜上动脉水平,左侧者位于左侧肾上腺与左侧膈肌脚之间,右侧者位于下腔静脉后方、右侧肾上腺内侧,主要为长条状(74.5%,178/239)、分叶状(25.5%,61/239)。腹腔神经节的左、右侧长径分别为(26.1±12.3)mm、(29.5±9.2)mm,短径分别为(4.1±1.0)mm、(3.1±0.9)mm,左侧腹腔神经节长径小于右侧(t=-4.208,P<0.001),左侧短径大于右侧(t=13.635,P<0.001)。结论 MDCT能显示腹腔神经节的位置、大小及形态特征,左侧腹腔神经节的显示率略高于对侧,但差别无统计学意义。

Objective To study the multi-detector CT findings of celiac ganglia.Materials and Methods Abdominal non-enhanced and enhanced multi-detector CT data of 133 subjects with normal findings were retrospectively reviewed.The location,morphologic feature,and size of the celiac ganglia were recorded and measured.Results Left celiac ganglia were showed in 124 subjects,not showed in 9 subjects,while right celiac ganglia were showed in 115 subjects and not showed in 18 subjects.There were no statistical difference for the display of celiac ganglia between left and right side（93.2% vs 86.5%,χ2=3.339,P=0.068）.Celiac ganglia were identified at the level between the origins of celiac and superior mesenteric arteries.The left ganglia was located between the left adrenal gland and diaphragm,and the right were identified posteromedial to the inferior vena cava and the inside of the right adrenal gland.They were thread-like（74.5%,178/239） or lobulated（25.5%,61/239）.The mean long-axis dimensions of the left and right were（26.1±12.3） mm,（29.5±9.2） mm,the left celiac ganglia were smaller than the right（t=-4.208,P0.001）.The mean short-axis dimensions of the left and right ganglia were（4.1±1.0） mm,（3.1±0.9） mm,the left celiac ganglia were larger than the right（t=13.635,P0.001）.Conclusion Multi-detector CT can show the location,size,morphologic feature of the celiac ganglia.The left celiac ganglia had higher display rate than right but without statistical difference.
