Six patients with persistent trigeminal artery (PTA) and one patient with its variant (PTAV) were studied using a 1.0-T magnetic resonance unit. With both magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), four of the six PTAs were detected as abnormal connecting arteries between the cavernous internal carotids and the basilar arteries. The remaining two PTAs and one PTAV were not detected using MRI, but were imaged by MRA. It was concluded that relatively large PTAs can be detected using MRI, but small PTAs and PTAVs may be missed using MRI.
使用1.0-T磁共振设备对6例持续性三叉动脉（PTA）患者和1例其变异型（PTAV）患者进行了研究。通过磁共振成像（MRI）和磁共振血管造影（MRA），6例PTA中的4例被检测为海绵窦段颈内动脉与基底动脉之间的异常连接动脉。其余2例PTA和1例PTAV未通过MRI检测到，但通过MRA成像。得出的结论是，相对较大的PTA可通过MRI检测到，但较小的PTA和PTAV可能会被MRI漏诊。
