【摘要】目的 探討正常成人肺靜脈開口徑線（pulmonary vein ostia，PVO）的測量方法，并獲得我院PVO徑線值的95%參考值范圍。方法 2005年6月-2006年1月收集無明顯心肺疾病的正常成人236例，對其進行多層螺旋CT掃描，利用斜冠面重建和三維標定的方法測量PVO徑線。結果四條PVO徑線的95%參考值范圍如下：右上肺靜脈長徑線為男性1.49~2.63 cm，女性1.31~2.37 cm，短徑線為男性0.87~2.05 cm，女性0.91~1.81 cm；右下肺靜脈長徑線為男性1.12~2.06 cm，女性1.05~1.95 cm，短徑線為男性0.77~1.83 cm，女性0.79~1.69 cm；左上肺靜脈長徑線為男性1.18~2.20 cm，女性1.09~2.11 cm，短徑線為男性0.82~1.72 cm，女性為0.80~1.62 cm；左下肺靜脈長徑線為男性0.96~1.98 cm，女性1.03~1.81 cm，短徑線為男性0.56~1.26 cm，女性0.51~1.33 cm。除左下肺靜脈短徑男女差異無統計學意義外，其余徑線值男性均大于女性。結論采用CT三維重建像改進測量方法測量PVO徑線值既簡便又準確。
【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.
