| 摘 要： | 目的：评价HRCT扫描结合MSCT动态增强扫描在诊断肺内孤立性结节（SPNs）的价值。方法：收集直径小于3cm的肺内孤立性结节患者48例,其中周围型肺癌28例,单发转移瘤5例,肺炎性假瘤5例,结核瘤4例,肺血管瘤2例,支气管肺腺瘤2例、肺错构瘤2例。48例患者均先行常规胸部CT扫描,然后对兴趣区行HRCT扫描,然后行胸部动态增强扫描,并测量其CT值增强幅度。结果：HRCT扫描结合MSCT动态增强扫描诊断肺内孤立性小结节的正确率为90%,HRCT扫描可以更好显示病灶边缘特征及内部结构,动态增强扫描可见肺内恶性结节大多均匀增强,且增强CT值大于20HU,平均增强CT值为35HU。良性结节多周边增强,且增强CT值小于10HU。结论：根据SPNs的HRCT基本形态特征,并结合MSCT动态增强扫描强化特征有助于肺内孤立性结节的定性诊断,提高术前诊断正确率。

| Abstract: | Objective:To evaluate the diagnostic value of high resolution and enhanced spiral CT in small pulmonary solitary nodules(SPNs).Methods:The plain,spiral and contrast enhanced CT data of 48 patients with SPNs less than 3 cm in diameter confirmed by pathology were retrospectively studied,among which 28 cases presented with peripheral lung cancer,with metastatic tumor,5 with inflammatory masses of the lung,4 with nodul tuberculoma,2 with hamartoma,2 with hemangioma.Results:The accurate rate of high resolutionen... |
