摘要
目的:评价CT在诊断和直肠癌分期的价值。材料和方法:回顾性分析150例经手术病理证实的直肠癌的CT表现,评价其CT诊断和分期的价值。结果:直肠癌CT的主要表现包括肠壁增厚50例、软组织肿块61例和肠腔狭窄49例;与手术病理对照,CT显示病灶、周围组织侵犯和淋巴结转移的准确性分别为96.7%(145/150)、88.4%(84/95)和51.7%(15/29);CT分期与Dukes分期的总符合率为83.3%。结论:直肠癌的CT诊断和分期与手术病理分期有很好的一致性,CT是直肠癌术前诊断的重要影像检查方法。
Purpose： To evaluate the CT in the diagnosis of rectal carcinoma and its staging. Materials and Methods： CT data of 150 cases of surgical pathologically verified rectal carcinoma were retrospectively reviewed to evaluate the accuracy in tumor detection and staging. Results： The imaging findings of rectal carcinoma on CT included wall thickening （n =50） , soft mass （n =61 ） and lumen narrowing （n = 49 ）. With reference to surgical and pathological findings, the accuracies of CT in detecting lesions, delineating perifocal invasion and lymph nodes metastasis is 96.7% （145/150）, 88.4% （84/95） and 51.7% （15/29）, respectively. The consistency between CT and Dukes stages is 83.3%. Conclusion： CT is well consistent with pathological stages on rectal carcinoma and it is helpful for its surgical planning.
