Figure 9.
Correlation between PAM and MRI data. (a) Amplitude: max. cavitation power vs. max. temperature rise. All of the data shown in Figure 7 and 8 is included, with 3 trials for each of the 6 conditions. (b) Location: peak in direction of FUS propagation observed with MRI thermometry vs. PAM. The data was analyzed in two groups based on the PSNE concentration: (i) Control and 2% PSNE (low/zero cavitation); (ii) 5–50% PSNE (cavitation). ρ = Pearson’s correlation coefficient, p = statistical significance from t-test.
