To Study the Role of Magnetic Resonance Imaging in the Diagnosis and Staging of Lung Cancer

目的研究磁共振成像在肺癌诊断和分期中的作用。方法选取2016年3月至2017年4月于我院接受治疗的360例肺癌患者作为此次研究对象。360例患者均经过组织活检确诊为肺癌,使用磁共振对所有患者进行全身扫描。将MRI检测结果与病理组织学结果进行比较,观察组磁共振检测肺癌的T、N分期准确率,比较不同类型的肺癌各个时期的病例状态、形态大小以及表观扩散系数值(ADC),以及化疗前和化疗1个月后各组患者的ADC值。结果 MRI检测结果与病理组织学结果比较T、N准确率较高,不同类型肺癌患者的ADC值具有明显差异,接受化疗前后,患者的ADC值比较差异显著。以上数据间比较差异有统计学意义(P<0.05)。结论磁共振对于肺癌患者的临床分期具有较为明显的效果,同时也是一种可以评价治疗效果的方式,可以作为临床诊断肺癌的首选方式。

Objective To study the role of magnetic resonance imaging in the diagnosis and staging of lung cancer. Methods 360 patients with lung cancer who were treated in our hospital from March 2016 to April 2017 were selected as the subjects. 360 patients were diagnosed with lung biopsy by tissue biopsy, and all patients were scanned with magnetic resonance. The MRI findings were compared with those of histopathological results. The frequency of T and N staging of lung cancer was detected by magnetic resonance imaging(MRI). The patients were compared with different types of lung cancer. The morphological size and apparent diffusion coefficient(ADC) were compared. The ADC values of each group were measured before and 1 month after chemotherapy. Results Compared with the histopathological results, the accuracy of T and N was higher, and the ADC values of patients with different types of lung cancer were significantly different. Before and after chemotherapy, the ADC was significantly different. The difference between the above data was statistically significant(P<0.05). Conclusion Magnetic resonance imaging has a significant effect on the clinical stage of lung cancer patients. It is also a way to evaluate the therapeutic effect. It can be used as the first choice for clinical diagnosis of lung cancer.
