【摘要】 目的：研究ＣＴ对直肠癌分期与手术病理所见的关系。方法：对３７例直肠癌术前ＣＴ分期与手术病理分期进行回顾性分析和比较。结果：本组ＣＴ确定直肠癌周围侵犯和分期的准确性分别为８４．５％和８３．８％（其中Ⅱ见期准确性为８１．９％， Ⅲａ期为８０％， Ⅲ期为８７．５％， Ⅳ期为 １００％），而确定淋巴结转移的准确性仅５０％。结论： ＣＴ能发现和显示病变，较准确估计病变对周围的侵犯情况及有否远处转移，因此ＣＴ对直肠癌的术前分期具有重要作用。更多还原

【Abstract】 Objedve:To compare the CT and pathologic swing of metal carcinoma.Methods: Compared with CT and pathologic staging in 37 cases of rectal carcinoma retrospectively. Results: The accuracy late of perirectal invasion and staging by CT were 84. 5 % and 83.8% (Ⅱ, Ⅲ a, Ⅲ b and Ⅳ staging of rectal carcinoma was 81 .9%, 80%, 87.5% and 100% respectively),however,for the metastatic lymph nodes,the accuracy rate by CT was only 50% .Conclusion:CT can find lesions, define the infiltrating range of the lesions and distant metastasis,so it plays an important role in defining tumors staging before operation.更多还原
