Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Patients with suspected ALS = 18 years referred to our neuromuscular outpatient clinic at the UMC Utrecht.

Exclusion criteria

Exclusion criteria: Patients with contra-indications for undergoing an MRI scan verified using MR contra-indications questionnaire (e.g. because of pacemaker, claustrophobia, metal implants, metal splinters in the eye) and with the inability to lie supine for 30 minutes for example due to respiratory difficulties.

Design outcomes

Primary

MeasureTime frame
The main study parameters are the presence and distribution of fasciculations measured with ultrasound and MRI.

Secondary

MeasureTime frame
Secondary study parameter(s):  - EDX-derived measures that are compatible with lower motor neuron loss (e.g. fibrillation potentials, large broad polyphasic motor unit potentials), and fulfillment of diagnostic consensus criteria (Awaji and Gold Coast criteria).  - Ultrasound-derived measures on muscle structure and architecture (e.g. muscle volume, echogenicity)  - MRI-derived measures muscle structure and architecture (e.g. muscle volume, signal intensity).
