摘要
目的:通过早期CT动态增强扫描,分析卵巢肿瘤血供状况,提高卵巢肿瘤定性诊断。方法:经手术和病理证实的卵巢肿瘤120例,其中良、恶性肿瘤各50例,交界性肿瘤20例。术前全部经CT动态增强扫描。重点分析早期瘤灶血供状况与肿瘤性质相关性。结果:良性组强化率为9?50例,占18%;分别见于肿瘤的囊性部分1例、囊实性部分6例、实性部分2例;恶性组强化率为31?50例,占62%;分别见于囊性部分4例,囊实性部分17例,实性部分10例;交界性组强化13例分别见于囊性部分1例,囊实性部分7例,实性部分5例,强化率为65%。统计学显示了不同性质瘤灶血供的差异性:良性组分别对比恶性组及交界性组存在着显著性差异(P<0.001)。而恶性组与交界性组之间对比则无明显差异(P>0.05)。结论:不同性质的卵巢肿瘤可能存在着血供差异。良性肿瘤缺乏血供或血供甚微,恶性肿瘤和交界性肿瘤都存在程度不等的血供现象。CT动态增强扫描能为瘤灶的血供状况提供有价值的信息。
Objective: To assess the diagnostic value of the early vascular perfusion in various kinds of ovarian tumors by CT scanning with early dynamic contrast-enhancement. Methods: Dynamic contrast enhanced CT scanning before operation was performed in 120 cases of ovarian tumors(50 benign, 50 malignant and 20 borderline) confirmed by operation and pathology. Results: Early perfusion of tumor foci seen in 9 cases of benign, 31 of malignant and 13 of borderline cases. Enhancement rate of ovarian tumors was 18% in benign, 62% in malignant, 65% in borderline cases respectively. There was markedly difference between benign and malignant tumors(P<0.001), as well as in benign and borderline cases(P<0.001), but there was no distinction in malignant and borderline cases(P>0.05). Conclusion: It may be short of blood supply in benign ovarian neoplasm, but on contrary in malignant and borderline cases different degree of vascular supply may exist. As a useful imaging information in differential diagnosis of ovarian neoplasm, dynamic contrast-enhanced CT scanning should be considered.
