Assessing Uterine Myomas and adenomyosis with BOLD Imaging After MRI-Guided Focused Ultrasound: Preliminary Findings

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.
