图2 一位单发急性脑梗塞复发患者磁共振轴位SE T1WI (a、c)、DWI (b、d)图像. 患者首次住院，行磁共振检查显示，左侧外囊单发腔梗呈长T1信号(a)，DWI弥散受限呈高信号(b)；患者康复出院后4个月出现临床症状，行磁共振检查显示，右侧顶叶单发腔梗灶，呈长T1信号(c)，DWI扩散受限呈高信号(d)

Fig. 2 Magnetic resonance axial SE T1WI (Fig. a, c) and DWI (Fig. b, d) of a patient with recurrent single lesion of acute stroke.The patient was admitted to the hospital for the first time, and an MRI showed a single lumen infarction in the left external capsule with a long T1 signal (Fig. a) and diffusion-limited DWI with a high signal (Fig. b). The patient developed clinical symptoms four months after discharge from rehabilitation, an MRI showed a single lumen infarction in the right parietal lobe with a long T1 signal (Fig. c) and diffusion-limited DWI with a high signal (Fig. d)
