目的:通过多排螺旋CT对早期周围型肺癌的诊断,提高对早期周围型肺癌征象的认识。方法:12例经病理和随访证实的早期周围型肺癌采用MSCT技术对肺癌结节征象进行综合分析。结果:所有肺癌结节在0.5~3 cm之间,11例为实性结节,磨玻璃密度1例,结节内见空泡征或(和)细支气管充气征3例,8例结节边缘呈浅分叶,3例结节边缘无明显分叶。胸膜凹陷征4例。结论:多排螺旋CT是早期周围型肺癌重要的检查方法,为周围型肺癌的早期发现和早期诊断开辟了新的途径。
OBJECTIVE: To improve the diagnosis of early-stage peripheral lung cancer by multi-slice spiral CT in the diagnosis of early-stage peripheral lung cancer. Methods: 12 cases of peripheral lung cancer confirmed by pathology and follow-up were analyzed comprehensively by using MSCT technique. Results: All lung cancer nodules ranged from 0.5 cm to 3 cm, solid nodules in 11, ground glass density in 1, nodular vacuoles or bronchioles in 3 and nodular in 8 The edge of the shallow lobe, nike free run, 3 cases no obvious edge of tubercle. Pleural depression sign in 4 cases. Conclusion: MSCT is an important method for early diagnosis of peripheral lung cancer. It opens up new avenues for the early detection and early diagnosis of peripheral lung cancer.
