摘要
目的探讨分析螺旋CT对肺磨玻璃结节的定性诊断准确性。方法研究对象为160例经病理检查确诊的肺磨玻璃结节患者,对所有患者行常规CT、螺旋CT检查,进行对比,并对良恶性患者不同螺旋CT表现进行分析。结果螺旋CT诊断准确性高于常规CT(P<0.05);螺旋CT检测出的恶性患者其病灶直径、病灶实质大于良性患者(P<0.05);良恶性患者病灶边缘不规则占比对比无统计学差异(P>0.05);恶性患者分叶征、毛刺征、胸膜凹陷占比高于良性患者(P<0.05)。结论对肺磨玻璃结节患者采取螺旋CT检查,所具诊断准确性较大,恶性患者病灶直径、病灶实质较高,且出现分叶征、毛刺征、胸膜凹陷比例较大,可为后续治疗提供一定支持。
Objective To investigate the qualitative diagnostic accuracy of spiral CT for ground-glass nodules in the lungs.Methods A total of 160 patients with ground-glass nodules confirmed by pathological examination were studied and all patients were compared with conventional CT and spiral CT,and the results of different spiral CT in benign and malignant patients were analyzed.Results The diagnostic accuracy of spiral CT was higher than that of conventional CT(P<0.05),the diameter and parenchyma of lesions detected by spiral CT were greater than those of benign patients(P<0.05),there was no significant difference in the proportion of irregular lesion margins in benign and malignant patients(P>0.05),and the proportions of lobulation sign,burr sign and pleural depression in malignant patients were higher than those in benign patients(P<0.05).Conclusion Spiral CT examination for pulmonary ground-glass nodules has high diagnostic accuracy,high lesion diameter and lesion parenchyma,and a large proportion of lobulation signs,burr signs and pleural depressions in patients with malignant patients,which can provide certain support for follow-up treatment.
