| 中文摘要: |
| 短暂性脑缺发作(TIA)是常见缺血性脑血管疾病,临床主要依据症状进行诊断,常规MR检查多无阳性发现。动脉自旋标记(ASL)主要反映脑血流灌注情况,无需使用对比剂,具有安全、无创、易重复的优点。近年来多种技术及序列的改良,可提高信噪比,改善图像质量,拓宽了技术的应用范围。本文就ASL的研究进展及其在TIA中的应用现状进行综述。 |
| 英文摘要: |
| Transient ischemic attack(TIA) is a common ischemic cerebrovascular disease, the mainly diagnosis methods is based on symptoms, and conventional MRI are also founding nothing. Arterial spin labeling(ASL) is a kind of perfusion imaging method, without injection of contrast agent, has the advantages of noninvasive convenient and easy to repeat. Recent years, the improvement of techniques and sequence signal-to-noise ratio and the image quality have widen the application of ASL. The research progress of ASL and its application in TIA were reviewed in this article. |
