Diffusion-weighted imaging as a non-gadolinium alternative for immediate assessing nonperfused area of adenomyosis after magnetic resonance-guided focused ultrasound (MRgFUS) ablation: a potential technique but with slightly overestimate.

ABSTRACT:

Background

It is a technical challenge to monitor ablation outcome during magnetic resonance-guided focused ultrasound (MRgFUS) treatment using non-gadolinium technique. The study aimed to investigate the value of diffusion-weighted imaging (DWI) for immediately assessing nonperfused area of adenomyosis after MRgFUS treatment.

Methods

We retrospectively included patients with adenomyosis who underwent MRgFUS ablation and underwent both DWI (b=800 sec/mm²) and contrast-enhanced (CE) magnetic resonance (MR) imaging within 15 minutes after treatment. Two blinded observers independently reviewed the DWI scan of the ablated necrotic lesions and measured their area in the central slice of DWI and CE imaging. Consistency and differences in the assessment result were comp
