目的：探讨肺部磨玻璃小结节定性诊断中采用CT多平面重建后处理技术的诊断价值。方法选取符合标准的患者86例，均行多层螺旋CT胸部检查后薄层重建，回顾性分析患者的临床病例资料，对肺部磨玻璃影像进行鉴别诊断，以病理结果作为诊断的标准，将其分为恶性组和良性组，同时选取多平面CT扫描层厚5mm为对照组，观察并分析其影像学特点。结果两组患者胸膜凹陷征、毛刺征、分叶征、空泡征及边界清楚等征象相比较，结果具有统计学差异(P<0.05)；两组患者在不规则形、圆或椭圆、斑片状及多结节融合状方面进行比较，结果具有统计学差异(P<0.05)；5mm层厚常规螺旋CT扫描与1mm薄层螺旋CT多平面重建对照，对GGO恶性征象的显示具有统计学意义(P<0.05)。研究显示：良性病变组多表现为圆或椭圆为主，恶性病变组多表现为不规则形和多结节融合状为主。结论螺旋CT多平面重建对肺部磨玻璃小结节定性诊断具有极高的临床应用价值。

Objective to explore the lung nodules in qualitative diagnosis use glass grinding the diagnostic value of CT multiplanar reconstruction postprocessing techniques. Methods Selection method conforms to the standard of 86 cases of patients, all row multislice CT chest thin layer after the reconstruction, patients were retrospectively analyzed clinical data, to the differential diagnosis of pulmonary grinding of glass image, with the pathological results as a diagnostic criteria, it can be divided into malignant and benign group, at the same time to choose more planar CT scanning layer thickness 5 mm for the control group, observe and analyze the imaging features. Results two groups of patients with pleural sag), burr, Ye Zheng, cavitation character and boundary clear signs, compared the results with statistical difference (P<0.05); Two groups of patients in irregular shape, round or oval, patchy and multiple nodules fusion shape comparison, the results statistically difference (P<0.05); 5 mm thick regular spiral CT scan and spiral CT multiplanar reconstruction of 1 mm layer control, of GGO malignant signs show statistically significant (P<0.05). Research shows that: the more benign lesion group characterized by round or oval, malignant lesion group is more irregular and multiple nodules fusion is given priority to. Conclusion Spiral CT multiplanar reconstruction of pulmonary grinding glass nodules qualitative diagnosis of great value in clinical application.
