ESWAN showed a higher rate of angiogenesis of recurrent
tumors than radiation necrosis. Observation of
susceptibility signals reliably correlates with the
increased tumor vascularity, particularly in recurrent
tumors. In conclusion, the implemented techniques supply
a qualitative method to permit prediction of tumor
response. Abundant signals indicated tumor recurrence.
