BACKGROUND AND OBJECTIVES: Cerebral adrenoleukodystrophy (CALD) is a common manifestation of adrenoleukodystrophy (ALD) in men. Early detection of CALD lesions through MRI screening is critical to allow for therapeutic action preventing severe disability and death. While the frequency of brain MRI monitoring has been addressed by international recommendations, no consensus currently exists regarding which MRI sequences should be used in a real-world setting for screening and follow-up of CALD lesions. The aim of this study was to establish guidelines for the MRI protocol in clinical practice and to identify priority sequences for research use, thereby promoting intercenter harmonization.
METHODS: A modified Delphi procedure was used to achieve consensus on MRI protocols for ALD screening, lesion monitoring, and research applications among experts with experience in brain imaging in ALD. Questionnaires allowed experts to indicate whether they considered sequences as core, optional, or research, or to express agreement (5-point scale ranging from completely disagree to completely agree) with specific statements. Topics where no agreement was reached were discussed during online consensus meetings.
RESULTS: Thirty experts from 9 countries participated and agreed that the core screening protocol for ALD in adults and children should include at least 3D T1-weighted, spin-echo T2-weighted, 3D fluid-attenuated inversion recovery, and diffusion-weighted imaging (DWI). Postcontrast T1-weighted imaging should be performed systematically in specific clinical scenarios. Experts supported using DWI alongside the Loes score and postcontrast imaging to assess lesion progression. A research protocol was defined, prioritizing diffusion tensor imaging, MR perfusion, and quantitative volumetric analyses.
DISCUSSION: This international project harmonizes the ALD MRI protocol, thus offering a practical framework to screen and monitor lesions, which will improve clinical decision making. It also identifies MRI sequences that should be prioritized in future research. Future research on MRI in ALD should focus on topics where no consensus has yet been reached in this project.
