多层螺旋CT分析周围型肺癌形态学特征—MPR正交重组切面结合MIP
Zhongshan Daxue xuebao. Yixue kexue ban, 2016 【目的】分析多层螺旋CT后处理图像（MPR正交重组切面结合MIP）对周围型肺癌形态学特征的显示价值。【方法】回顾性纳入75例（男：女= 36:39；平均年龄：60.0岁）术前行64排CT检查并经手术病理证实为周围型肺癌的孤立性肺结节。记录结节形态学特征（边缘，分叶征、血管集束征、胸膜凹陷征、毛刺征）分别在横断位，冠、矢状切面及MPR正交重组切面结合MIP（5 mm）图像上的显示率、诊断结果，进行对比分析。【结果】MPR平行肺门支气管血管束方向5 mm MIP 明显提高肺结节血管集束征的检出率 ...

Zhongguo shiyan zhenduanxue, 2005 目的探讨CT跟踪对重症急性胰腺炎的诊断价值。方法回顾性分析重症急性胰腺炎22例。结果发病后4896小时就可以进行Balthazar CT分级。CT影像均有不同程度的胰腺肿大;部分病例有胰腺密度减低、低密度坏死灶和胰腺周围积液。CT跟踪证实了Balthazar CT分级随着病情变化而改变。结论CT跟踪和Balthazar CT分级可以作为监测胰腺及其周围结构改变的首选方法,也为手术治疗重症急性胰腺炎提供了最重要的依据。
