CT多平面重建在肺部磨玻璃结节诊断中的应用

Application of CT Multiplanar Reconstruction in the Diagnosis of Pulmonary Ground Glass Nodules

目的探讨CT多平面重建在肺部磨玻璃结节定性诊断中的应用效果。方法回顾性分析2017年8月-2019年8月医院90例CT检查中发现磨玻璃结节患者的资料,以病理学诊断结果将其分为两组,即恶性组42例与良性组48例。本组研究对象均接受CT多平面重建,比较两组磨玻璃小病灶形态学(多结节融合状、斑片状、圆或椭圆、不规则形)与影像学(毛刺征、空泡征、边界清晰、分叶征与胸膜凹陷征)情况。结果恶性组多结节融合状、斑片状、不规则形的发生率高于良性组(P<0.01),圆或者椭圆的发生率低于良性组(P<0.01)。恶性组毛刺征、空泡征、边界清晰、分叶征与胸膜凹陷征的发生率均高于良性组(P<0.05或P<0.01)。结论 CT多平面重建在肺部磨玻璃结节定性诊断中具有显著的应用价值,可以有效识别出肺部磨玻璃结节的形态与影像。

Objective To investigate the application of CT multiplanar reconstruction in the qualitative diagnosis of small glass nodules in the lung. Methods A retrospective analysis of the data of 90 patients with frosted glass nodules found in our hospital from August 2017 to August 2019. The pathological diagnosis results were divided into two groups, namely 42 cases in the malignant group and benign. Group 48 cases. All subjects in this group underwent CT multiplanar reconstruction, comparing the morphology of small glass grinding lesions(multiple nodular fusion, patchy, round or elliptical, irregular shape) and imaging(burr sign, vacuole sign, Clear borders, lobulated signs and pleural depression. Results The incidence of multinodular fusion, patchy, and irregular shape in the malignant group was higher than that in the benign group(P<0.01). The incidence of round or ellipse was lower than that in the benign group(P<0.01). The incidence of burr sign, vacuole sign, clear boundary, lobulated sign and pleural indentation in malignant group were higher than those in benign group(P<0.05 or P<0.01). Conclusion CT multiplanar reconstruction has significant application value in the qualitative diagnosis of pulmonary ground glass nodules. It can effectively identify the morphology and imaging of small glass nodules in the lung, which is worthy of clinical application.
