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.
The technique was applied to 3 patients having hemangiomas in the head and neck region. In 1 patient the image obtained with the proposed technique was compared to that obtained by standard contrast angiography.
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.
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.
评估一种用于头颈部血管瘤（包括血管畸形及其供血动脉）三维（3D）检测的新技术。该新技术将无需造影剂的相位对比磁共振血管造影（PCMRA）与三维快速不对称自旋回波（FASE）序列相结合。
该技术应用于3名头颈部患有血管瘤的患者。在1例患者中，将用该新技术获得的图像与通过标准造影血管造影获得的图像进行比较。
在所有3例患者中，在所提出的技术生成的图像中，血管瘤和供血动脉的三维存在情况均清晰可辨。此外，在同时进行了造影血管造影的病例中，血管瘤的三维结构特征和供血动脉的分布与造影血管造影观察到的情况相符。
初步经验表明，所提出的结合三维FASE和三维PCMRA的技术在不使用造影剂的情况下，对于可视化血管瘤的三维结构以及识别供血动脉的三维分布是有用的。
