目的分析CT与MRI成像在初诊食管癌分期中的临床应用价值。方法选择2011年10月至2012年11月初诊食管癌的患者242例,所有患者均采用胸部CT及MRI检查。观察患者的病理学结果及其CT、MRI特征。结果在T1、T2期食管癌诊断中,MRI诊断的灵敏度与准确性明显高于CT,差异有统计学意义(P<0.05);MRI在N0、N1期诊断中灵敏度高于CT,差异有统计学意义(P<0.05);将CT、MRI联合诊断准确性、灵敏度与单独应用相比,差异有统计学意义(P<0.05)。结论 CT与MRI对诊断食管癌均有明显作用,MRI在T1、T2期及N0、N1期诊断中敏感性较高,将CT与MRI联合应用可提高诊断的准确性及灵敏度,临床医生可将CT及MRI联合应用作为诊断食管癌的首选方法。
Objective To analyze the clinical value of CT and MRI imaging in newly diagnosed esophageal cancer staging. Methods A total of 242 patients with newly diagnosed esophageal cancer from October 2011 to November 2012 were selected. All patients underwent chest CT and MRI. Observe the patient’s pathological findings and CT, MRI features. Results The sensitivity and accuracy of MRI diagnosis in T1 and T2 esophageal cancer were significantly higher than those in CT (P <0.05). The sensitivity of MRI in diagnosis of N0 and N1 was higher than that in CT, the difference was statistically significant (P <0.05). The diagnostic accuracy and sensitivity of CT and MRI were significantly different from those of single application (P <0.05). Conclusion CT and MRI have obvious effect on the diagnosis of esophageal cancer. MRI is more sensitive in the diagnosis of T1, T2 and N0, N1. The combination of CT and MRI can improve the accuracy and sensitivity of diagnosis. Combined CT and MRI as the method of choice for the diagnosis of esophageal cancer.
