In this study, we have implemented T2-based monitoring
of near-field heating in patients, undergoing HIFU
ablation of uterine fibroids using Insightec ExAblate
system. In certain areas, near-field heating can reach
18C and the tissue may experience sustained heating of
more than 10C for the period of 2 hours or more. This
indicates a cumulative thermal dose that may cause
necrosis. Our results show the feasibility and
importance of measurement of near-field heating in
subcutaneous fat.
