# A 65‐year‐old woman with ALS and bilateral precentral motor band sign

## TL;DR

This paper describes a case where advanced MRI techniques helped identify a specific brain sign in a woman with ALS, aiding early diagnosis.

## Contribution

The paper highlights the use of QSM and other MRI techniques to detect the 'motor band sign' in ALS for the first time.

## Key findings

- QSM MRI revealed a distinct 'motor band sign' in a patient with ALS.
- The motor band sign indicates upper motor neuron involvement in ALS patients.

## Abstract

Advanced MRI techniques, including SWI, MinIP, and QSM, are instrumental in detecting the “motor band sign” in ALS, aiding in the early diagnosis and assessment of upper motor neuron involvement, which is critical for therapeutic interventions.

MRI with advanced techniques such as QSM reveals a distinct “motor band sign” in a patient with ALS, indicating upper motor neuron involvement.
