目的探讨子宫内膜癌的超声造影增强特点、时间-强度曲线参数特征及其临床价值.方法选择30例子宫内膜癌患者进行实时超声造影检查,观察其增强特点;比较造影前后癌灶测值的变化;应用QLAB软件制作时间-强度曲线,比较癌灶与未受累肌层在曲线参数上的差异.结果造影增强特点:造影剂最先到达癌灶的滋养血管,由此分支进入癌灶,达峰时布满癌灶内部(除坏死区).73.3%(22/30)的癌灶退出早于肌层.76.7%(23/30)的癌灶供血来源得以显示,43.3%(13/30)的癌灶显示比常规超声更加清晰.85%(17/20)的癌灶造影后测值大于常规超声,增大平均值(0.62±0.50)cm.时间-强度曲线分析:90%以上的曲线显示癌灶早于或与肌层同时开始增强并达峰值,癌灶组的进入时间、达峰时间明显早于肌层组;癌灶组达峰强度、上升强度和增强速率显著高于肌层组.结论子宫内膜癌的超声造影表现有一定的规律,能提供较常规超声更加丰富的影像学信息.

Objective To observe the enhancement pattern and time-intensity curve of endometrial carcinomas by using contrast-enhanced ultrasound(CEUS). Methods Altogether 30 endometrial carcinomas were evaluated with real-time gray-scale CEUS, using pulse inversion harmonies technique. The enhancement patterns were observed. Twenty tumors were compared for the size between traditional ultrasound and CEUS. In 21 cases, the parameters of time-intenaity curve were compared between the endometrial lesion and un-involved myometrium. Results The contrast agent arrived at the feeding vessels firstly and then branched into the endometrial tumors. All of the endometrial tumors were enhanced completely except for the necrosis area. In 73.3 % (22/30) of cases, the tumors washed out earlier than the un-involved myometrium. By using CEUS 76. 7% (23/30) of cases showed the feeding vessels of tumor. 43.3% (13/30) of cases showed more clearly than traditional ultrasound in tumor base, position and boundary. The mean enhancement sizes of tumor were bigger than the size showed by traditional ultrasound in 85% of cases by (0. 62±0.50)cm. More than 90% cases showed the tumors start to enhance and wash-out earlier than or at the same time as myometrium. The arrival time and peak time of cancer group were significantly earlier than myometrium group. The peak intensity, enhancement intensity and the rising rate of the tumor group were significantly higher than those of the myometrium group. Conclusions There are some characteristic points in CEUS of endometrial carcinomas. CEUS can provide richer information in tumor imaging than traditional ultrasound and has certain clinical value.
