摘要
目的探讨CT和磁共振成象(MRI)检查对食管癌术前原发肿瘤分期和区域性淋巴结转移的评判价值。方法选取2009年至2012年间收治的术后经病理确诊的食管癌患者91例,其中行CT检查者53例(CT组),行MRI检查者38例(MRI组),回顾性分析两组患者术前影像学检查对食管癌术前原发肿瘤分期和有无区域性淋巴结转移的评判,并与术后病理结果进行对照。结果 CT组患者的食管癌术前原发肿瘤分期(T分期)的诊断准确率为83.0%,MRI组患者的食管癌术前原发肿瘤分期(T分期)的诊断准确率为79.0%,差异无统计学意义(P>0.05);在纵隔淋巴结转移(N分期)和腹部淋巴结转移上CT组的灵敏度、特异度、准确度分别为81.5%、76.9%、79.3%和78.6%、80.0%、79.3%,而MRI组的灵敏度、特异度、准确度分别为84.2%、79.0%、81.6%和85.0%、83.3、84.2%,两组间差异无统计学意义(P>0.05)。结论 CT和MRI检查对食管癌术前原发肿瘤分期和区域性淋巴结转移评判效果相当,但CT价格较低,操作较简单,值得临床推广。
Objective To compare and observe computed tomography and magnatic resonance imaging judgment value on primary tumor classification and regional lymphatic metastasis.Methods Chose 91 cases of these esophagus cancer patients who have had operation at our hospital from 2009 to 2012,divided them into CT group（53 cases receiving CT scan） and MRI group（38 cases receiving MRI scan）,retrospectively analyzed two groups imageological examination judgment value on primary tumor classification and regional lymphatic metastasis before treatment,and compared the results with after operation＇s.Results CT group patients＇ accurate diagnosis rate of T stage toward primary tumor before esophagus cancer operation was 83.0%,while MRI group was 79.0%,there were no obvious difference between the two groups（P0.05）;With regard to mediastinum lymphatic metastasis（N stage） and belly lymphatic metastasis,CT group sensitivity,specific degree and accuracy were 81.5%、76.9%、79.3% and 78.6%、80.0%、79.3%,while MRI group were 84.2%、79.0%、81.6% and 85.0%、83.3%、84.2%,there were no significant differences between the two groups（P0.05）.Conclusions Computed tomography and magnatic resonance imaging judgment value on primary tumor classification and regional lymphatic metastasis has no significant difference,but CT examination is more cheap,and its operation is more simple,it is worthy of clinical promotion.
