Changes in T2w, T2, T1, ADC, blood flow, and APTw images acquired at the different time points (baseline, 1 day postradiation, and 4 days postradiation) for a rat with a U87 glioma. The display windows are T2 (0–100 ms), T1 (0.5–2 s), ADC (0–2 × 10−9 m2/s), blood flow [0–200 ml/(100 g/min)], and APTw (−10% to 10% of the bulk water signal intensity). All images share the same scale bar as in the baseline T2w image.
