Renal ablation using magnetic resonance-guided high intensity focused ultrasound: Magnetic resonance imaging and histopathology assessment

Figure 1 A localizer was performed to verify the position of the kidneys relative to the transducer. Coronal T2-weighted (T2-W) magnetic resonance images show the result of added T2-W treatment planning sequence, which was transferred to the high intensity focused ultrasound software (left and center). The right plot shows the temperature rise during ablation in the renal parenchyma. The red temperature curve represents the maximum temperature measured at the point of focus, while the green curve represents the average temperature in the region of interest.
