摘要 目的:探讨肠道原发性恶性肿瘤的CT定位、定性诊断,并评估CT分期诊断价值。材料方法:回顾分析16例经病理证实的原发性肠道恶性肿瘤的CT表现,包括腺癌10例、淋巴瘤4例、平滑肌肉瘤2例。结果:16例肿瘤CT检出敏感性100%。CT定位正确14例,定性肠道恶性肿瘤13例。三种肿瘤CT表现各有特征,而肠壁增厚和/或肿块为其共同特点;CT分期时对肿瘤局部侵犯及淋巴转移敏感性较差,但特异性很高。结论:肠道肿瘤CT定位、定性诊断准确性较高,CT分期有一定局限性,但CT对肿瘤局部侵犯与淋巴结转移阳性检出的特异性很高,仍有临床价值。 PURPOSE:To discuss the value of CT diagnosis on categorization、Iocation and staging of the primary malignant tumors of intestine. MATERIALS AND METHODS:The CTfeatures in 16 cases with primary malignant tumors of intestines were analysed, combined with surgeon and pathology. The tumors included adenocarcinoma 10 cases,lymphoma 4 cases and leiomyoscrcoma 2 cases. RESULTS:The sensetivity of the tumors detected by CT in the whole 16 cases was 100% with the accuracy of location 88% and of categorization 81%. It showed these three kinds of tumors had their own CTcharacters, while remarkable and irregular thickening of intestine wall and/or mass were their common CT features, The sensetivity on stagin by CT about the neoplasms' extramural invasion and lymph node metastases was a bit lower, but with a higher specificity. CONCLUSION:The accuracy of categorization and location of the tumors diagnosed by CT was higher. There was some limitations in staging by CT,but because of its higher specificity, once the positive findings of the tumors extramural invasion or metastases were detected by CT, it's valuable for treatment.
