BACKGROUND AND PURPOSE: Evaluation of alar traumatic injuries by using MR imaging
is frequently performed. This study investigates the variability of morphology and signal …

Study Design: This study analyzed anatomic characteristics of the alar ligaments and the
possibility of imaging them with magnetic resonance imaging. Also determined was whether …

An observational study of variations in the appearance of the alar ligament on magnetic
resonance imaging (MRI) and the normal range of lateral flexion and rotation of the atlas …

Study Design. Cross-sectional study. Objective. To evaluate the association between degree
of signal changes in the alar ligaments on MRI with respect to pain and disability. Summary …

Objective. The alar ligament plays a critical role in limiting the axial rotation of the head, the
left alar ligament being stretched on rotation to the right and vice versa. The purposes of this …

Rupture of the alar and transverse ligaments due to whiplash injury can lead to upper
cervical spine instability and subsequent neurological deterioration. The purpose of this …

Study Design. A prospective study of healthy volunteers. Objective. To evaluate the
influence of magnetic resonance imaging (MRI) field strength on the delineation and signal …

Objective A precise anatomical description of the alar ligaments is important to better
understand their biomechanical and pathologic implications. Although there are several …

Study Design. Case-control study. Objective. To use high-resolution magnetic resonance
imaging (MRI) in assessing signal intensity areas in the alar ligaments. Summary of …

OBJECT The alar ligaments (ALs) are vital for stabilizing the craniocervical junction. In terms
of morphology, their appearance varies and is visible on MRI. Dark signal of the AL on …
