Free Area of the Spinal Canal and Torg's Ratio in Acute Cervical Trauma and Degenerative Disease: MANCOVA and Correlational Analyses.

Background: The two of the most common indications for magnetic resonance (MR) imaging of the cervical spine include acute spine trauma and degenerative disease.

Objective: We aimed to correlate the measurements of the free area of the spinal canal (FASC), a new approach to the cervical spinal canal compromise, with the Torg´s ratio quantification of the cervical spine.

Methods: A cross-sectional study including 50 cervical-spine MR evaluations of patients with acute cervical trauma or degenerative disease was performed.

[Imaging anatomy of the cranial nerves using 3.0 Tesla MRI: a practical review for clinicians].

Magnetic resonance (MR) imaging is the method of choice to evaluate the cranial nerves (CN). These nerves constitute a group of structures that have acquired during their phylogenetic development a high degree of specialization. There are 12 pairs of CN to which we use their specific name or number.
