摘　　要：目的基于高分辨率CT(HRCT)靶扫描技术分析肺磨玻璃结节(GGN)与支气管、血管的关系及对浸润性病变的诊断价值。方法回顾性选取经HRCT检查发现GGN且具有完整病理结果的患者为研究对象,采用HRCT靶扫描技术进行扫描。分析不同病理类型患者GGN与支气管、血管的关系,以病理结果为金标准,分析GGN与支气管、血管的关系对浸润性病变的检出效能。结果300例患者按照病理结果分为浸润前病变237例,浸润性病变63例。不同类型GGN患者病灶性质、病灶形态比较,差异有统计学意义(P<0.05)。浸润前病变和浸润性病变GGN与支气管、血管的关系类型比较,差异均有统计学意义(P<0.05)。以病理结果为金标准,HRCT支气管分型、血管分型及两者联合检出浸润性病变的敏感度为84.13%(53/63)、95.24%(60/63)、95.24%(60/63),特异度为83.12%(197/237)、87.34%(207/237)、87.34%(207/237),准确性为83.33%(250/300)、89.00%(267/300)、89.00%(267/300)。结论HRCT靶扫描技术评估肺GGN与支气管、血管的分型对于鉴别浸润性病变均具有良好价值,2种征象联合诊断可进一步提高检测的准确性。Objective To analyze the relationships between pulmonary ground-glass nodules(GGN)and bronchi and blood vessels and their diagnostic values for infiltrative lesions based on high-resolution computed tomography(HRCT)target scanning technology.Methods Patients with GGN detected by HRCT target scanning and complete pathological results were retrospectively selected as the research subjects.The relationships between GGN and bronchi and blood vessels in patients with different pathological types were analyzed,and the relationships for detecting infiltrative lesions were further analyzed,using pathological results as the gold standard.Results Three hundred patients were divided into 237 cases of pre-invasive lesions and 63 cases of infiltrative lesions according to pathological results.There were statistically significant differences in lesion properties and lesion morphology in patients with different types of GGN(P<0.05).There were statistically significant differences in the relationships between GGN and bronchi and blood vessels in the pre-invasive lesions and the infiltrative lesions(P<0.05).Based on the pathological results as the gold standard,the sensitivity of HRCT bronchial classification,vascular classification,and their combined detection of infiltrative lesions were 84.13%(53/63),95.24%(60/63),and 95.24%(60/63);specificity were 83.12%(197/237),87.34%(207/237),and 87.34%(207/237);accuracy were 83.33%(250/300),89.00%(267/300),and 89.00%(267/300).Conclusion Evaluating the classification of pulmonary GGN and bronchi and blood vessels by HRCT target scanning technology has good value in identifying infiltrative lesions.The combined diagnosis of the two signs can further improve the accuracy of detection.
