Fig 2. The progression of the NPV over 48 hours.

Fig 2

(A) The NPV of 4 individual animals at 0, 6, 24, and 48 hours post ultrasound ablation. (B) The mean NPV of all single spot ablation animals at 0, 24, and 48 hr post HIFU ablation. Although there appears to be a large increase in the NPV post treatment (between 6–8 hours), the NPV at 48 hours is not significantly different from the immediate post treatment results suggesting that regions not well perfused on contrast enhanced T1w imaging may be indicative of ultimate tissue damage.
