摘要
目的分析肺内小结节病灶影像学特征。方法收集82例经手术病理证实肺内直径小于等于2cm孤立结节病变,均行数字化体层摄片和CT扫描并结合影像学特征进行分析。结果恶性肿瘤61例,良性肿瘤7例,炎性结节14例。恶性结节边缘毛刺征和分叶征,数字化体层摄影检出率为97%和90%,CT检出率为95%和88%。而良性结节边缘毛刺征和分叶征为14%、28%和14%、14%。结论边缘毛刺征和分叶征是诊断恶性肿瘤最可靠依据,而数字化体层摄影是目前最有效检查方法之一,如与CT结合可大大提高肺部小结节病灶诊断率。
Objective To analyse the imaging patterns of small solitary pulmonary nodules.Methods The imaging patterns of 82 cases of small solitary pulmonary nodular lesions were analysed by digital tomography and computed tomography.All cases of solitary pulmonary nodular lesions which were smaller than 2 cm in diameter were confirmed by surgical operation and histopathology.Results Of 82 cases,there were 61 cases of malignant tumors,7 cases of benign tumors and 14 cases of inflammatory nodules.Digital tomography and computed tomography showed blurred or thin spiculate outlines in 97 % and 90 % ,lobular signs in 95 % and 88 % respectively in malignant nodules,whereas blurred or thin spiculate outlines in 14 % and 28 % ,lobular signs in 14 % and 14 % respectively in benign ones.Conclusion The features of blurred outline and lobular sign on nodules are most reliable evidences for diagnosing the malignant tumor.The integration of digital tomography and computed tomography can improve significantly the qualitative diagnosis of intrapulmonary nodules.
