摘要：目的:比较CT与MRI对周围型肺癌的诊断价值。方法:回顾性分析我院从2013年1月到2015年1月89例周围型肺癌患者的CT及MRI资料,评估两种方法对肿瘤内部结构与周围特征的检测情况以及对周围型肺癌的临床诊断价值。结果:肿瘤直径小于5cm的患者,CT显示肿瘤内部结构情况:空泡65个、空洞53个、细支气管征51个;MRI显示肿瘤内部结构情况:空泡16个、空洞25个、细支气管征46个,两者差异有统计学意义(P<0.05)。肿瘤直径大于5cm的患者,CT及MRI检测对于肿瘤内部结构与周围特征检出情况接近,差异不具有统计学意义(P>0.05)。CT检出肿大淋巴结136个,肺癌转移瘤59个;MRI检出淋巴结198个,转移167个,差异有统计学意义(P<0.05)。CT与MRI对肺癌的误诊率分别为51.69%和50.56%,检出率分别为41.57%和39.33%,差异均不具有统计学意义(P>0.05)。结论:在肿瘤内部结构与周围特征的检测情况方面,当肿瘤直径大于5cm时,CT与MRI对周围型肺癌的诊断价值无明显差异;当肿瘤直径小于5cm时,CT对肺癌的诊断价值明显高于MRI;在对淋巴结肿大及肺癌转移检出情况方面,MRI的价值明显高于CT。
Objective： To compare the clinical diagnostic value of appling CT and MRI in peripheral lung cancer. Methods： A retro- spective analysis of 89 patients with peripheral lung cancer from Jan 2013 to Jan 2015 in our hospital. Detection of CT and MRI of the patients were admitted to analyse and evaluate in which the internal structure of tumor,detection state of surrounding features,and clinical diagnostic value on peripheral lung cancer were evaluated between CT and MRI data. Results： Small than 5cm of the diameter of patients＇ tumor, CT de- tection for tumor internal structure and the surrounding features： 65 vacuoles,53 cavities,51 bronchus sign; MRI detection for tumor internal structure and the surrounding features： 16 vacuoles,25 cavities,46 bronchus sign;there was statistically significant between CT and MRI （P〈0.05）.Great than 5em of the diameter of patients＇ tumor, the internal structure of tumor,and detection state of surrounding features were roughly the same in which the difference was not statistically significant between CT and MRI （P〉0.05）. CT detection：136 swelled lymph nodes, 59 lung metastasis ; MRI detection： 198 swelled lymph nodes, 167 lung metastasis ; the difference was statistically significant and de- tection rate（P〈0.05） in which MRI technology for the lymph node and tumor invasion, effusion of patients were better than CT. The misdiagno- sis rate in CT and MRI were respectively 51.69% and 50.56%,41.5% and 39.33% in which the difference were all not statistically significant （P〉0.05）.Conelusions： Through the comparison results of CT and MRI in diagnosing peripheral lung cancer, two kinds of detection methods have their own characteristics.Great than 5em of the diameter of patients＇ tumor, detection method of CT and MRI in the internal structure of tumor, and detection state of surrounding features for peripheral lung cancer patients were statistically significant （P〈0.05）. Small than 5cm of the diameter of patients＇ tumor, CT is better than MRI in diagnosing peripheral lung cancer, MRI is better than CT in swelled lymph nodes and lung metastasis.
