The practical evaluation of" vascular-signal" weighted image applied for MRI-ASL(arterial spin labeling) technique

我们用动脉自旋标记(ASL)对烟雾病(MMD)进行了灌注成像，并将ASL-PI与临床、其他MRI和SPECT表现进行了比较。ASL有助于评价MMD的血流动力学改变。对颅内硬脑膜动静脉瘘或症状性癫痫患者的ASL-PI显示血流动力学行为，提示对他们的随访有帮助。我们确定仔细评估脑肿瘤患者的ASL-PI。

We examined perfusion imaging by arterial spin labeling(ASL) on moyamoya disease(MMD) and compared ASL perfusion imaging(ASL-PI) with clinical, other MRI findings and SPECT findings in MMD. ASL is expected to be helpful for evaluating the hemodynamic changes in MMD. ASL-PI on patients with intracranial dural arteriovenous fistulas or symptomatic epilepsy showed the hemodynamic behavior, and suggested to be useful for their follow-up. We identified to estimate the ASL-PI on the patient with brain tumor carefully.
