肺挫伤的256层螺旋CT诊断研究

DIAGNOSTIC VALUE OF 256-SLICE SPIRAL CT ON LUNG CONTUSE

目的探讨多层螺旋CT对肺挫伤的诊断价值。方法分析240例肺挫伤患者的CT资料，将其分为二大类型和五亚型，观察不同类型肺挫伤与胸廓骨折、不同年龄的关系。结果肺挫伤类型与胸廓骨折之间的差异有统计学意义（P〈0．05）；局限胸膜型、局限非胸膜型、广泛单侧型、广泛散在型、广泛弥漫型肺挫伤与胸廓骨折之间的差异均有统计学意义（P〈0．05）；各型肺挫伤与各年龄段构成之间的差异有统计学意义（P〈0．05）。结论胸廓骨折发生与肺挫伤类型无关；25岁以下的患者较易发生广泛的肺挫伤，25岁～组患者较易发生局限的肺挫伤。

Objective To explore the value of 256- slice spiral CT（MSCT） in diagnosis lung contuse. Methods MSCT features of lung contuse in 240 cases were analyzed retrospectively. Its classified into two main groups and five subgroups according to the location of the injury and the distribution of the focus. Finally the relationships of among various kinds of lung contuse, the fracture of the chest and different ages could be observed. Results There were statistic significance in the dissimilarity between the different kinds of lung contuse and the chest fracture （P〈0.05） ; There were also statistic significance in the difference between limited, wide-ranging and various kinds of lung contuse and chest fracure. Conclusion There is no relation between various kinds of lung contuse and chest fracture. It is likely that people under 25 tend to have wide- ranging lung contuse and that people above 25 tend to have limited lung contuse.
