螺旋CT水造影检查对结直肠癌的诊断价值

The value of water ene ma spiral CT in diagnosis of colorectal cancer

目的探讨螺旋CT结直肠低张水造影技术对结直肠癌在术前诊断和分期中的应用价值。方法对90例临床怀疑结直肠癌的患者进行低张水造影螺旋CT扫描检查。结果90例患者中经手术或病理证实34例结直肠癌患者,螺旋CT诊断结直肠癌的主要征象是平扫为肠腔内实质性肿块,肠壁局限性不规则增厚及肠腔非对称性狭窄等,增强为均匀或不均匀强化。分期的总符合率为67.6%。结论螺旋CT扫描对结直肠癌的诊断和分期有较高的临床价值。它不仅能发现和显示病变,可明确病变范围和侵及情况,对肿瘤术前分期、选择治疗方法及判断预后有重要作用。

Objective To explore the application value of water ene ma spiral CT（Wesct）in the diagnosis and staging of colorectal cancer.Methods The Wesct scanning were underwent in 90 patients with colorectal cancer.Results Thirty-four patients were diagnosed with colorectal cancer pathologically and／or surgically.The primary CT features on plain scanning of colorectal cancer were solid tumor mass in the intestine,local increasing of the wall and irregular rectal obliteration,the lessions appeared the homogenous or inhomogenous strenthening.The coincidence rate for TNM-staging of colorectal cancer was 67.6%.Conclusion Wesct is valuable in diagnosis and staging of colorectal cancer,it is not only able to detect and display the lessions,but also determine the extent and infiltration of the lessions.Wesct could play an important role in tumour staging,choice of treatment methods and prognosis.
