【摘要】：目的:探讨多层CT(MSCT)三期动态增强扫描对肾透明细胞癌(CCRCC)、嫌色细胞癌(CRCC)及嗜酸细胞腺瘤(OA)的鉴别诊断价值。方法:采用双盲法回顾性分析经手术及病理证实的55例CCRCC、16例CRCC及9例OA患者的CT图像,比较三者在肿瘤大小、性质(实性、囊实性及囊性)、校正强化CT值以及强化形式(均匀强化、不均匀强化及周边强化)等方面的差异。结果:(1)三组肿瘤最大径无显著性差异。(2)CRCC以实性为主,CCRCC以囊实性为主,OA实性与囊实性所占比例相仿,三者间有显著性差异(χ~2=14.10,P0.001)。(3)皮髓质期CCRCC校正强化CT值高于CRCC及OA(P0.001),而CRCC与OA间无显著性差异(P0.05);实质期CCRCC校正强化CT值高于CRCC(P0.001),而CCRCC与OA及CRCC与OA间无显著性差异(P0.05),OA校正强化CT值介于CCRCC与CRCC之间;排泄期CRCC校正强化CT值低于CCRCC与OA(P0.05),而CCRCC与OA间无显著性差异(P0.05)。(4)强化形式比较,CCRCC与CRCC及CCRCC与OA间差异具有统计学意义(χ~2=15.89,P0.001和χ~2=11.15,P0.05),而CRCC与OA间差异无统计学意义(P0.05)。结论:肿瘤的校正强化CT值是鉴别肾肿瘤类型的一个重要指标,而肿瘤的成分性质及强化形式也具有一定的鉴别意义。
[Abstract]:Objective: to evaluate the differential diagnosis of CCRCCT, chromophobe cell carcinoma (CRCCCC) and eosinophil adenoma (OAA) with multilayer CTT MSCT in 55 cases of renal clear cell carcinoma (CCRCC). Methods: 55 cases proved by operation and pathology were retrospectively analyzed by double blind method. Ct images of 16 patients with CRCC and 9 patients with OA. The size, nature (solid, cystic, and cystic) of the tumor, the corrected CT value and the enhancement form (uniform enhancement) were compared among the three groups. Results there was no significant difference in the maximum diameter of tumor in the three groups. The majority of CCRCC was solid, and the proportion of OA solid and cystic solid was similar to that of CCRCC. There was significant difference among the three groups (蠂 ~ (2) P ~ (14. 10) P 0.001 ~ (-1)). The CT value of CCRCC correction in medullary phase was higher than that of CRCC and OAP 0.001, but there was no significant difference between CRCC and OA (P 0.05). The CT value of CCRCC correction in substantive phase was higher than that of CCRCC (P 0.001), but there was no significant difference between CCRCC and OA and CRCC and OA (P 0.05). The value of CT was between CCRCC and CRCC. The CT value of CRCC correction enhancement in excretory phase was lower than that of CCRCC and OAA P0.05, but there was no significant difference between CCRCC and OA. Conclusion: there was significant difference between CCRCC and CRCC and between CCRCC and OA (蠂 2 + 15.89%, P 0.001, 蠂 ~ 2 + 11.15 P 0.05), but there was no significant difference between CRCC and OA (P 0.05). The corrected enhanced CT value of tumor is an important index to distinguish the type of renal tumor. The character of tumor components and the enhancement form also have certain differentiation significance.
