APT and conventional MR images for different stage patients. (A) F/50 years, a hyperacute stage patient at 2 h after symptom onset. APTWave = −0.83%, APTWmax–min = 1.30%. (B) M/54 years, an acute stage patient at 17 h after symptom onset. APTWave = −0.63%, APTWmax–min = 0.99%. (C) F/62 years, an early subacute stage patient at 72 h after symptom onset. APTWave = −0.40%, APTWmax–min = 0.72%. (D) M/54 years, a late subacute stage patient at 120 h after symptom onset. APTWave = 0.03%, APTWmax–min = 0.53%.
