Molecular Imaging-Guided Interventional Hyperthermia in Treatment of Breast Cancer

Figure 5

(a) Axial CE three-point Dixon gradient-echo images (150/12.8, 19.8, and 26.8; flip angle = 90°) of the first patient in prone position, showing the enhancing tumor mass (arrow) lateral in the right breast with the hypointense fully deployed LeVeen needle electrode centrally in the center of the mass. (b) Axial CE three-point Dixon gradient-echo images (150/12.8, 19.8, and 26.8; flip angle = 90°) of the same patient in prone position showing the magnetic resonance PRF shift thermomap (yellow zone: 49°C, orange: 61°C, and red 73°C) around the hypointense deployed LeVeen needle electrode centrally in the mass (arrow). (c) Postprocedure CE water-selective, spectral-spatial axial FSE image of the right breast demonstrates a small enhancing rim representing the border of the ablation zone corresponding to fresh scar tissue (arrows).
