摘要 目的:探讨后处理分析软件(ALA)在肺结节随访中的应用价值。方法:采用GE Lightspeed Pro 16后处理工作站AW4.2的ALA数据后处理软件,对136例患者肺部有结节的数据进行处理(其中96例有不同时间的随访复查),显示结节的特征,并测定其倍增时间及生长率,并与病理结果或最终临床诊断作比较。结果:ALA软件可对不超过30mm的结节进行三维容积分析,测定其体积,计算倍增时间(DT)及生长率。结论:ALA软件在肺结节的测定中具有较高的准确性,可以为SPN的定性诊断提供良好的帮助。 Objective：To evaluate tile appliation value of ALA software in solitary pulmonary nodules. Methods： 136 patients who had the solitary pulmonary nodules underwent 16-helical CT with high resolution restruefion, in which 96 patients had the follow-up CT scan in different time. All the data were analysed by ALA software of GE AW4. 2 workstation to show the eharaeteristie of nodules, to measure the volume, and to calculate the doubling time and growth rate. Results： The solitary pulmonary nodules with sizes less than 30 mm can be reconstructed. The volume, growth rate, and doubling time can be calculated by the ALA software. Conclusion：The ALA software has the high accuracy in the mensuration of solitary pulmonary nodules and has the great value in the diagnosis.
