【摘要】 目的  探讨正常成人肺静脉开口径线（pulmonary vein ostia，PVO）的测量方法，并获得我院PVO径线值的95%参考值范围。 方法  2005年6月-2006年1月收集无明显心肺疾病的正常成人236例，对其进行多层螺旋CT扫描，利用斜冠面重建和三维标定的方法测量PVO径线。 结果  四条PVO径线的95%参考值范围如下：右上肺静脉长径线为男性1.49~2.63 cm，女性1.31~2.37 cm，短径线为男性0.87~2.05 cm，女性0.91~1.81 cm；右下肺静脉长径线为男性1.12~2.06 cm，女性1.05~1.95 cm，短径线为男性0.77~1.83 cm，女性0.79~1.69 cm；左上肺静脉长径线为男性1.18~2.20 cm，女性1.09~2.11 cm，短径线为男性0.82~1.72 cm，女性为0.80~1.62 cm；左下肺静脉长径线为男性0.96~1.98 cm，女性1.03~1.81 cm，短径线为男性0.56~1.26 cm，女性0.51~1.33 cm。除左下肺静脉短径男女差异无统计学意义外，其余径线值男性均大于女性。 结论  采用CT三维重建像改进测量方法测量PVO径线值既简便又准确。
【Abstract】 Objective  To measure and calculate the diameters of pulmonary vein ostia (PVO) by multi-slice spiral computed tomography (MSCT) in healthy people. Methods  From June 2005 to January 2006, 236 healthy people were adopted to undergo MSCT. Their diameters of PVO were measured and calculated by oblique coronal planes reconstruction and 3D position-setting. Results  Right superior vein: the 95% reference ranges of the long diameters were 1.49-2.63 cm in the male and 1.31-2.37 cm in the female;the ranges of the short diameters were 0.87-2.05 cm in the male and 0.91-1.81 cm in the female. Right inferior vein: the ranges of the long diameters were 1.12-2.06 cm in the male and 1.05-1.95 cm in the female;the ranges of the short diameters were 0.77-1.83 cm in the male and 0.79-1.69 cm in the female. Left superior vein: the ranges of the long diameters were 1.18-2.20 cm in the male and 1.09-2.11 cm in the female;the ranges of the short diameters were 0.82-1.72 cm in the male and 0.80-1.62 cm in the female. Left inferior vein: the ranges of the long diameters were 0.96-1.98 cm in the male and 1.03-1.81 cm in the female;the ranges of the short diameters were 0.56-1.26 cm in the male and 0.51-1.33 cm in the female. The diameters in the male were all longer than those in the female, except the short diameter of left inferior vein. Conclusions  It is a convenient and accurate method to measure the diameters of PVO by blique coronal planes reconstruction and 3D position-setting.
