目的：探究足月新生儿动脉缺血性脑梗死(NAIS)早期磁共振成像(MRI)特点与不同 MRI 序列的 NAIS 诊断价值。方法回顾性分析16例 MRI 确诊为 NAIS 患儿的临床资料及 MRI 资料。结果16例患儿在常规的 MRI 检查中13例 T1WI 信号异常；16例 T2WI 信号异常。16例患儿在首次磁共振扩散加权成像(DWI)检查中均出现了异常的信号。结论常规 MRI 检查可以帮助了解 NAIS 的病情， DWI检查可以早期判断 NAIS。NAIS 早期磁共振血管造影(MRA)大多数显示病区大脑中动脉(MCA)分支增多，与成人的脑梗死血管狭窄或完全闭塞不同。
目的：探究足月新生兒動脈缺血性腦梗死(NAIS)早期磁共振成像(MRI)特點與不同 MRI 序列的 NAIS 診斷價值。方法迴顧性分析16例 MRI 確診為 NAIS 患兒的臨床資料及 MRI 資料。結果16例患兒在常規的 MRI 檢查中13例 T1WI 信號異常；16例 T2WI 信號異常。16例患兒在首次磁共振擴散加權成像(DWI)檢查中均齣現瞭異常的信號。結論常規 MRI 檢查可以幫助瞭解 NAIS 的病情， DWI檢查可以早期判斷 NAIS。NAIS 早期磁共振血管造影(MRA)大多數顯示病區大腦中動脈(MCA)分支增多，與成人的腦梗死血管狹窄或完全閉塞不同。

Objective To investigate early magnetic resonance imaging (MRI) characteristics of full-term neonatal arterial ischemic stroke (NAIS) and diagnostic value research of NAIS by different MRI sequence. Methods A retrospective analysis was made on clinical data and MRI data in 16 diagnosed NAIS infants by MRI. Results Among the 16 cases, there were 13cases with abnormal T1WI signal in conventional MRI examination and 16 cases with abnormal T2WI signal. All the 16 cases had abnormal signal in the first examination by diffusion weighted imaging (DWI). Conclusion Conventional MRI examination can show condition of NAIS, and DWI examination can provide early diagnosis of NAIS. Early magnetic resonance angiography (MRA) of NAIS mainly shows increased middle cerebral artery (MCA) branches, which is different from hemadostenosis or vascular occlusion in adult cerebral infarction.
