| 目的 通过与常规CT对照,评价3.0T MRI对周围型肺癌各种征象的显示能力及诊断价值。方法 对30例周围型肺癌行3.0T MR 成像,通过与常规CT对照分析周围型肺癌征象包括病灶部位、形态、大小、边缘特征、肿瘤内部结构、瘤周改变及与支气管的关系等的检出及显示能力。结果 3.0T MRI对显示周围型肺癌病灶部位、形态、大小、肿瘤内部结构及邻近胸膜改变的显示能力与CT比较无明显统计学差异(P＞0.05)。3.0T MRI对显示周围型肺癌边缘特征及小支气管的改变方面与CT比较有明显统计学差异(P＜0.05)。结论 3.0T MRI可以较好地显示周围型肺癌的大部分征象,可作为影像学检查的一种有效补充手段。 |

| Objective To compare the detection performance of 3.0T MRI for various signs of the peripheral lung cancer with conventional CT, and to evaluate the diagnostic value of 3.0T MRI for the peripheral lung cancer. Methods Thirty patients with peripheral lung cancer underwent 3.0T MRI. The imaging signs including the tumor site, shape, size, the intra-tumor structure, changes around the tumor and relationship with bronchus on MRI were compared with conventional CT. Results The visualization of tumor margin and the small bronchus changing were more clear on CT image than on MRI (P＜0.05). MRI had no statistical significance in the tumor site, shape, size, the intra-tumor structure and pleural involvement with CT (P＞0.05). Conclusion Most signs of peripheral lung cancer could be demonstrated well on 3.0T MRI. 3.0T MR imaging can be a supplementary imaging technique for peripheral lung cancer. |
