Arterial spin labeling (ASL) imaging soon will be available as a routine clinical perfusion imaging sequence for a significant number of MR imaging scanners. The ASL perfusion technique offers information similar to that provided by conventional dynamic susceptibility sequences, but it does not require the use of an intravenous contrast agent, and the data can be quantified. The appearance of pathology is affected significantly by the ASL techniques used. Familiarity with the available sequence parameter options and the common appearances of pathology facilitates perfusion interpretation.
动脉自旋标记（ASL）成像很快将作为一种常规临床灌注成像序列应用于大量磁共振成像扫描仪。ASL灌注技术提供的信息与传统动态磁敏感序列相似，但它不需要使用静脉造影剂，并且数据可以量化。所使用的ASL技术会显著影响病变的表现。熟悉可用的序列参数选项和病变的常见表现有助于灌注解读。
