摘要
目的 探讨中心型肺癌支气管腔的形态变化。方法 对 10 0例经病理证实的中心型肺癌行螺旋CT扫描 ,应用SSD方法对支气管三维成像。结果 支气管狭窄 43例 ,呈鼠尾状、偏心状、串珠状和不规则状狭窄 ;支气管梗阻 5 7例 ,呈截断性、斜状、不规则状梗阻和先狭窄后梗阻 ,狭窄和梗阻后支气管显影 18例。结论 螺旋CT三维成像能良好地显示支气管腔的形态变化。
Objective To evaluate the shapes of intrabronchial cavity in central lung cancer.Methods One hundred cases of central lung cancer proved by pathology were scanned with spiral CT and bronchial three-dimensional imaging were reconstructed with SSD method. Results SSD showed the shapes of bronchiostenosis in 43 patients were mouse tail, eccentric, toruloid and irregular, shapes of bronchial obstruction were truncate, oblique, irregular in 57 cases and bronchial cavity display following stenosis and obstruction in 18 cases. Conclusion The bronchial cavity change is well displayed by spiral CT three-dimensional reconstruction.
