Despite the huge impact of lower motor neuron dysfunction on the patients' independence, survival and quality of life, muscle imaging is a glaringly overlooked frontier of MND/ALS research. This is a missed opportunity, as a variety of non-invasive quantitative muscle imaging techniques have been successfully used in other neurological conditions; these protocols are easy to implement on commercial MRI and ultrasound platforms and recent studies have demonstrated their ease of use and potential clinical utility.
Toomey et al. (2026) studied this question.
