Synopsis

Keywords: Pelvis, Treatment, HIFU

Motivation: Evaluating treatment efficacy of high-intensity focused ultrasound (HIFU) is crucial for physicians to determine whether the procedure is complete.

Goal(s): This preliminary study validates the use of T2*-mapping with iDEAL-IQ for evaluating the treatment effects of HIFU without contrast injection.

Approach: A decrease in T2* values was observed in the lesion region between different oxygenation conditions, while equal or increased values were noted after treatment.

Results: These preliminary results suggest that T2* mapping could be an effective tool for treatment assessment.

Impact: T2*-mapping, which can reveal the variations in oxygenation, would be an effective tool for assessing treatment outcomes of high-intensity focused ultrasound (HIFU) in uterine myomas and adenomyosis, without the need for contrast injection.
