多层螺旋CT在肺部磨玻璃影良恶性鉴别诊断中的应用价值

目的：讨论多层螺旋CT在肺部磨玻璃影良恶性鉴别诊断中的应用价值。方法：选取行螺旋CT胸部检查的31例患者资料，对肺部磨玻璃影像进行鉴别诊断，以病理结果作为诊断标准，将其分为恶性组（18例）和良性组（13例），分析其影像学特点。结果：两组在胸膜凹陷征、毛刺征、分叶征及边界清楚征象比较差异显著，具有统计学意义（x2=7.300，x2=6.183，x2=5.373， x2=8.791；P＜0.05）。恶性病变以胸膜凹陷征、毛刺征及分叶征等表现为主，边界清楚；两组在圆或椭圆型、不规则形及多结节融合状比较差异显著，具有统计学意义（x2=11.138，x2=6.482， x2=4.306，P＆lt;0.05）。良性病变表现为圆或椭圆型，恶性病变以不规则形和多结节融合状表现为主。结论：通过多层螺旋CT在胸部检查中的应用，对磨玻璃影的特殊征象及形态学进行综合分析和良恶性鉴别，具有极高的应用价值。

The value in the differential diagnosis of benign and malignant in pulmonary ground-glass opacities with multislice spiral C T

Objective： To discuss the value in the differential diagnosis of benign and malignant in ulmonary ground-glass opacities with multislice spiral CT. Methods： Selected 31 patients in Beijing North hospital with spiral CT examination of the chest as the research object, the lungs differential diagnosis of ground-glass image analysis to pathological findings as diagnostic criteria, analysis Imaging features of benign and malignant grinding glass shadow. Results： Malignant lesions with pleural indentation, spiculation, lobulation, such as performance-based, clear boundary between the two groups in the pleural indentation, spiculation, points Ye Zheng, clear boundary comparing with statistical significance（x2=11.138, x2=6.482, x2=4.306, P〈0.05）. Meanwhile benign lesions showed a round or oval, and malignant lesions with irregular shape and multi-nodular-like performance-based fusion of the two groups in a round or oval, irregular and more fusion-like nodules difference was significant, the statistical significance （x2=11.138, x2=6.482, x2=4.306, P〈0.05）. Conclusion：Application of multislice spiral CT examination of the chest can be on the ground glass by special signs and morphological comprehensive analysis, benign and malignant, with a high value.
