目的:利用计算机后处理程序对孤立性困难肺结节(与胸膜、血管相连的结节及磨玻璃结节)进行分割,获得结节的形态特征,辅助医生诊断,评判计算机辅助分割在困难肺结节中的临床应用价值。方法回顾性分析经病理证实的52例困难肺结节的影像资料,其中14例与胸膜相连、18例与血管相连,20例磨玻璃结节。利用数学形态学及随机游走方法对结节进行分割,提取出结节边缘信息,并与手术病理结果进行对照,上述两者进行统计学分析。结果52例困难肺结节经上述方法去除了胸膜及血管的影响,并对磨玻璃肺结节进行交互式分割,提取出结节的精确数据;其中44例与手术病理结果进行对照无明显统计学差异。结论经病理学证实,采用数学形态学及随机游走运算对困难肺结节进行处理,实现了结节的精确分割,显示结节的边缘形态及体积大小,有利于结节良、恶性的鉴别。
目的:利用計算機後處理程序對孤立性睏難肺結節(與胸膜、血管相連的結節及磨玻璃結節)進行分割,穫得結節的形態特徵,輔助醫生診斷,評判計算機輔助分割在睏難肺結節中的臨床應用價值。方法迴顧性分析經病理證實的52例睏難肺結節的影像資料,其中14例與胸膜相連、18例與血管相連,20例磨玻璃結節。利用數學形態學及隨機遊走方法對結節進行分割,提取齣結節邊緣信息,併與手術病理結果進行對照,上述兩者進行統計學分析。結果52例睏難肺結節經上述方法去除瞭胸膜及血管的影響,併對磨玻璃肺結節進行交互式分割,提取齣結節的精確數據;其中44例與手術病理結果進行對照無明顯統計學差異。結論經病理學證實,採用數學形態學及隨機遊走運算對睏難肺結節進行處理,實現瞭結節的精確分割,顯示結節的邊緣形態及體積大小,有利于結節良、噁性的鑒彆。

Objective To study the computer processing program to segment the solitary pulmonary nodules (connected with the pleura,blood vessels and ground glass nodules),acquire the morphological characteristics of the nodules and assist the diagnosis.To evaluate the clinical value of computer aided segmentation in difficult pulmonary nodules.Methods The imaging data of 52 cases of difficult pulmonary nodules confirmed by pathology,including 14 cases connected with the pleura,18 cases connected with blood vessels and 20 cases with ground glass nodules were analyzed retrospectively.Mathematical morphology and random walk method to segment the nodules were used,and the edge information was extracted,which were compared with pathology results and analyzed statistically.Results Accurate data of 52 cases of difficult pulmonary nodules were extracted.By the methods of removing the effects of pleura and vessels,and interactive segmention of the ground-glass nodules,there were no significant statistical differences with pathological results in 44 cases.Conclusion Using mathematical morphology and random walk algorithm process can achieve the ac-curate segmentations of difficult pulmonary nodules,show the nodules’edge shapes and sizes.It is helpful to the differential diagno-sis between benign and malignant nodules.
