子宫肌瘤动脉血管网数字化三维模型构建与特点

摘要/Abstract

摘要：

目的利用基于CT血管成像（CTA）三维重建技术构建的子宫肌瘤动脉血管网数字化三维模型，探讨子宫与子宫肌瘤的血管网特点。方法连续采集2012年1月至9月于南方医科大学南方医院接受CTA检查的72例子宫肌瘤患者的原始数据集，构建子宫肌瘤动脉血管网数字化三维模型，通过逐步调整阈值以改变模型的血管显示密度，并予透明化处理后作分析。结果成功构建了72例患者的子宫肌瘤动脉血管网数字化三维模型，该模型可清晰的显示子宫动脉及子宫肌层、子宫肌瘤的血管网，可见肌壁间、浆膜下、黏膜下子宫肌瘤的血管网轮廓与子宫血管网的相对位置不同，其中浆膜下肌瘤轮廓显示最为清晰。重建模型中存在特殊类型的肌瘤血管网。结论利用CTA和重建软件构建出的子宫肌瘤动脉血管网数字化三维模型形态逼真，可准确识别子宫肌层与子宫肌瘤的血管网，为术前评估和临床教学提供参考。

Abstract:

Abstract:Objective To analysis the characteristics of blood supply to the uterus and uterine fibroid by using of the digital 3D model of arterial vascular network of uterine myoma based on the CT angiography(CTA) data. Methods Selected 72 patients with uterine fibroids performed dual-source CT in Nanfang Hospital sequentially. The model of uterine fibroid digital 3D arterial vascular network was reconstructed with Mimics 10.01 software. Adjust the threshold of the model gradually in order to change the density of vascularity and analysis the characteristics of vascular network. Results 72 digital 3D models of uterine fibroid arterial vascular network were reconstructed, it reveals uterine artery, vascular network of myometrium and uterine fibroid clearly. Positions between vascular network of intramural fibroid, subserosal fibroid, or submucosal fibroid and that of uterus were different, outline of subserosal fibroids vascular network was the most clearly. There was special type of fibroid vascular network in the models. Conclusion Vascular network of myometrium and uterine fibroid can be identified successfully by using of the digital 3D model of arterial vascular network of uterine myoma based on the CTA. The model provides useful reference for the preoperative evaluation and the teaching in clinical practice. 
