目标。评估一种用于头部和颈部血管瘤的三维（3D）检测技术，包括血管畸形及其喂养动脉。新技术将无造影剂的相位对比磁共振血管造影（PCMRA）与3D快速不对称自旋回波（FASE）序列相结合。该技术应用于3例头颈部血管瘤患者。在1例患者中，采用该技术获得的图像与标准对比血管造影获得的图像进行了比较。在所有3例患者中，血管瘤和供血动脉的三维存在在该技术创建的图像中被很好地定义。此外，血管瘤的三维结构和供血动脉的分布特征与对比血管造影观察到的吻合，对比血管造影也进行了。初步经验表明，将3D- fase和3D- pcmra相结合的技术有助于在不使用造影剂的情况下可视化血管瘤的3D结构和识别供血动脉的3D分布。
Objective. To evaluate a proposed technique for the 3-dimensional (3D) detection of hemangiomas, including vascular malformation and their feeding arteries, in the head and neck. The new technique combines phase-contrast magnetic resonance angiography (PCMRA) without contrast medium and 3D fast asymmetric spin-echo (FASE) sequences.Methods. he technique was applied to 3 patients having hemangiomas in the head and neck region. In I patient the image obtained with the proposed technique was compared to that obtained by standard contrast angiography.Results. in all 3 patients, the 3D presence of the hemangiomas and the feeding arteries were well defined in images created by the proposed technique. Additionally, the characterization of the hemangioma's 3D structure and distribution of the feeding arteries coincided with those observed using contrast angiography in the case for which contrast angiography was also performed.Conclusions. Preliminary experience shows that the proposed technique combining 3D-FASE and 3D-PCMRA is useful to visualize both the 3D structure of hemangiomas and to identify the 3D distribution of the feeding arteries without using contrast medium.
