摘　　要：目的:采用256层螺旋计算机断层摄影术(MSCT)对右心耳及其毗邻的形态结构进行定量研究,为右心耳临床介入和外科治疗提供影像学依据。方法:回顾性分析我院行计算机断层摄影术血管造影(CTA)检查结果阴性者200例,男96例,女104例,<40岁者29例,40~60岁者114例,>60岁者57例。将原始扫描数据进行右心耳重建,对右心耳容积及径线等参数进行测量,并从性别和年龄方面进行比较,提出右心耳各参数95%正常参考值范围。结果:(1)右心耳容积、高度、基底部长径、基底部周长、正位展距男性均大于女性,差异均有统计学意义(P均<0.05)。经体表面积标化后,右心耳基底部长短径、面积及周长女性均大于男性,差异均有统计学意义(P均<0.05)。(2)<40岁者右心耳正位展角及正位展距较40~60岁及>60岁者大(P<0.05),40~60岁者与>60岁者间差异无统计学意义(P>0.05)。(3)提出右心耳各参数95%正常参考值范围:容积4.83~19.97 ml、高度21.46~41.80 mm、基底部长径25.89~41.65 mm、基底部短径19.34~36.24 mm、基底部面积459.30~1 093.28 mm^2、基底部周长86.16~147.04 mm、正位展角1.67°~31.23°、正位展距8.07~34.37 mm。结论:256层MSCT可以对右心耳解剖结构相关参数进行定量研究,并初步建立右心耳各参数95%正常参考值范围,为临床治疗右心耳相关疾病提供影像学参考。Objective： To quantitatively study the morphological structure and parameter of right atrial appendage（RAA） by 256-slice spiral CT to provide RAA imaging reference for interventional or surgical therapy in clinical practice.Methods： A total of 200 patients with negative CTA results examined in our hospital were studied including 96 male and 104 female; by age division, Age≤40 years group, n=29, Age（40-60） years group, n=114 and Age〉60 years group, n=57. The original scanning data was reconstructed for RAA establishment, indexes of volume, radial lines were measured and compared between different gender and age groups to obtain 95% normal imaging references of RAA.Results：① The volume, height, basilar part circumference, anteroposterior spread of RAA in male were greater than female, all P〈0.05; with surface area standardization, the long and short diameter of basilar part, area, circumference in female were greater than male, all P〈0.05.② Anteroposterior angle and spread of RAA in Age40 years group were higher than both Age（40-60） years group and Age〉60 years group, P〈0.05, the above parameters were similar between Age（40-60） years group and Age〉60 years group, P〉0.05.③ 95% normal reference ranges of RAA were as following： volume（4.83-19.97） ml, height（21.46-41.80） mm; basilar part longest diameter（25.89-41.65） mm, short diameter（19.34-36.24） mm, area（459.30-1093.28） mm2, circumference（86.16-147.04） mm; anteroposterior angle（1.67-31.23） °, spread（8.07-34.37） mm.Conclusion： 256-slice CT may quantitatively study the morphological structure and parameter of RAA and establish its 95% normal imaging references for clinical practice.
