The Value of Multiple Image Signs on High Resolution CT in Differential Diagnosis between Benign and Malignant Solitary Pulmonary Nodules
-
摘要: 目的：分析肺内孤立结节（SPN）的多种高分辨CT征象对其良、恶性的鉴别诊断价值。方法：对我院从2016年4月到2018年4月间手术病理证实的102例SPN的CT图像加以分析，对比分析联合或单一高分辨CT征象判断恶性病变的阳性预测值。结果：恶性病变中钙化发生率为4.26%，较良性病变中钙化率低。恶性病变中分叶征、血管集束征与毛刺征发生率分别为63.83%、40.43%与70.21%，均较良性病变中发生率高，差异均具有统计学意义（P<0.05）。良、恶性病变高分辨CT征象中，卫星灶、空泡征和胸膜凹陷征发生率差异均无统计学差异（P>0.05）。联合血管集束征、毛刺征与分叶征中两种或者三种，联合诊断恶性病变的阳性预测值均较单一征象高，差异均有统计学意义（P<0.05）。结论：SPN的高分辨CT征象对其良、恶性的鉴别价值较高，联合多种CT征象较单一征象的价值大。Abstract: Objective: To assess the value of multiple imaging signs on high-resolution CT in the differential diagnosis between benign and malignant solitary pulmonary nodules (SPN). Methods: 102 cases of SPN with surgery or pathologically confirmed from April 2016 to April 2018 were retrospectively analyses. The data's of multiple image signs on high-resolution CT for diagnosing benign and malignant lesions were collected, and the diagnosis accuracy of combined and single signs were compared. Results: The incidence of calcification in malignant lesions was 4.26%, which was lower than that of benign lesions. The incidences of lobulation signs, vascular bundle signs and burrs signs were 63.83%, 40.43% and 70.21% respectively in malignant lesions, all of these were higher than those of benign lesions. All of the differences mentioned above were statistically significant (P<0.05). No significant differences were shown in the incidence of satellite foci, vacuolar sign and pleural depression between benign and malignant lesions (P>0.05). The positive predictive value of combined signs of vascular bundle signs, burr signs and lobulation signs was significantly higher than that of single sign (P<0.05). Conclusion: High-resolution CT signs are of high value in the differential diagnosis of benign and malignant SPN, and combined multiple CT signs is higher accuracy than single CT sign.
