BACKGROUND AND PURPOSE: Hirayama disease is a benign focal amyotrophy of the
distal upper limbs involving C7, C8, and T1 segmental myotomes with sparing of the …

The objective of the study was to study the magnetic resonance imaging (MRI) features of
Hirayama disease on a 3 Tesla MRI scanner. Nine patients with clinically suspected …

Although flexion cervical MRI has been recommended for the diagnosis of Hirayama
disease (HD), no study focused on the MR features at different neck flexion angles …

PURPOSE: To investigate the sensitivity and specificity of various neutral-position magnetic
resonance (MR) imaging findings in the diagnosis of Hirayama flexion myelopathy …

This study reports on cervical magnetic resonance imaging (MRI) performed in the fully
flexed position in 13 male patients with Hirayama disease and 12 normal controls (males) …

Purpose: To evaluate the MR findings in clinically suspected cases of Hirayama disease.
Materials and Methods: The pre and post contrast neutral and flexion position cervical MR …

BACKGROUND AND PURPOSE: Most studies of HD have been conducted in Asia,
particularly Japan. To characterize the MR imaging findings of North American patients with …

OBJECTIVE: Forward shifting of the posterior cervical dural sac is the most important sign in
diagnosing Hirayama disease but can also be seen in normal subjects, causing potential …

Background Hirayama's disease (HD), is a benign, self-limited, motor neuron disease,
characterized by asymmetric weakness and atrophy of one or both distal upper extremities …

Background: Hirayama disease (HD) is benign focal amyotrophy of the distal upper limbs,
often misdiagnosed as motor neuron disease. Routine magnetic resonance imaging (MRI) is …
