摘　　要：目的通过256iCT动静脉双期扫描，分析卵巢肿瘤血供状况及强化方式，以提高卵巢肿瘤的定性准确率。方法经病理证实的卵巢肿瘤110例，其中良、恶性肿瘤各45例，交界性肿瘤20例。术前全部经cT动静脉期扫描。分析肿瘤血供与性质相关性。结果良性组强化率为8／45，占17．8％，见于肿瘤囊性部分1例、囊实性部分4例、实性部分3例；恶性组强化率为30／45例，占66．7％，见于囊性部分3例，囊实性部分15例，实性部分12例；交界性强化强化率为12／20，占60％，见于囊性部分2例、囊实性部分6例、实性部分4例。统计学显示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（X2=22．04、11．59，P〈0．01）。恶性组与交界性组对比无明显差异（X2=0．27，P〉0．05）。结论不同性质的卵巢肿瘤存在强化方式及血供差异。良性肿瘤为乏血供，呈轻度强化。恶性肿瘤和交界性肿瘤存在程度不等的血供，多为明皿强化。cT双期扫捕能为瘤灶的血供状况及定性提供有价值的信息。Objective To analyze the blood-supplying status and enhancement methods of ovarian tumors through 256-slice dual-phase arteriovenous CT scanning so as to improve the diagnostic accuracy of ovarian tumors. Methods The 256-slice dual-phase CT scanning was performed preoperatively in 110 cases of ovarian tumor patients （45 benign tumors, 45 malignant and 20 borderline） who were confirmed through pathology to analyze the correlation between the blood-supplying status and the type of tumors. Results The enhancement rate of the benign group was 8/45, accounting for 17.8%; malignant group was 30/45, accounting for 66.7%, borderline group was 12/2, accounting for 60.0%. Statistics showed that there were significant differences in the blood-supplying status in different types of tumors： significant differences existed when the benign group was compared with the malignant group and the borderline groups respectively（P〈0.01）; there were no significant differences in comparison of the malignant group with the border group （P〉0.05）. Conclusion The blood-supplying status and enhancement methods in different types of ovarian tumors were varied. Features of lacking blood supply and slight enhancement were revealed in benign tumors. There were diversified degrees of blood supply and obvious enhancement in malignant tumors and borderline tumors. Dual-phase CT scanning was of great significance in identifying the blood-supplying status and the type of tumors.
