CT和MRI在孤立性肺结节中的诊断价值

Diagnostic value of CT and MRI in solitary pulmonary nodules.

目的:了解CT和MRI对孤立性肺结节的诊断缺陷及协同作用的意义。方法:回顾性分析111例孤立性肺结节,分析其CT和MRI 征象。结果:111例中恶性肿瘤81例,其中肺癌80例,包括鳞癌25例,腺癌42例,小细胞未分化癌5例,大细胞未分化癌1例,肺泡细胞癌7例; 直肠腺癌肺转移1例。病灶直径1.5-4 cm,平均(3．10±0．77)cm。良性病变共30例,其中肺结核8例,错构瘤6例,隐球菌感染2例,炎性假瘤 6例,慢性非特异性炎症4例,炎性肉芽肿2例,脓肿1例,球形肺不张1例;病灶直径0．8-4 cm,平均(2．47±0．94)cm。结论:孤立性肺结节患者的影像学检查,CT和MRI选其一,目前仍以CT为首选。

Objective：To study the diagnosis and coordination of CT and MRI in solitary pulmonary nodules. Methods： To retrospective analyze the characteristics of CT to 111 cases with solitary pulmonary nodule. Results：There were 83 male cases and 28 female cases. Their ages ranged from 27 to 87 with an average of 59 years old. in the 111 cases, there were 81 cases with malignant tumor of 111 cases. 80 cases with lung cancer, including 25 cases with squamous cell carcinoma,42 cases with adenocarcinoma,5 cases with small cell undifferentiated carcinoma, 1 case with large cell undifferentiated carcinoma,7 cases with alveolar cell carcinoma, and 1 case with rectal adenocarcinoma by lung metastasis. The diameter of lesions was 1.5-4 cm with an average of 3.10 0. 77 cm. 30 cases with benign lesions,including 8 cases with tuberculosis,6 cases with hamartoma, 2 cases with mycosis,6 cases with inflammatory pseudotumor,4 cases with chronic nonspecific inflammation,2 cases with inflammation granuloma, 1 case with abscess,and 1 case with globular atelectasis. The diameter of cases ranged from 0.8cm to 4cm with an average of 2.47±0.94cm. Conclusions： Imaging examination on solitary pulmonary nodules, no matter CT or MRt,CT remains the first priority at present.
