Cervical Cord to Canal Diameter Ratio

March 21, 2022 updated by: Jin Yong Jung, Daegu Catholic University Medical Center

Comparison Between the Coronal Diameters of the Cervical Spinal Canal and Spinal Cord Measured Using Computed Tomography and Magnetic Resonance Imaging in Korean Patients

Cervical epidural block could cause spinal cord injury if the epidural needle is over-inserted and punctures the spinal cord. Investigators retrospectively evaluated the imaging data of 100 patients (50 men and 50 women) who underwent both cervical computed tomography (CT) and cervical magnetic resonance imaging (MRI) at our hospital. Investigators measured the diameters of the spinal canal and spinal cord from the 3rd cervical vertebra to the 1st thoracic vertebra (T1) at each level by using the patients' cervical CT and MR images. The spinal cord and spinal canal diameters were measured in the transverse plane of cervical MR and CT images, respectively.

Detailed Description

The spinal canal diameter, i.e., the epidural transverse diameter, was measured as the distance between the innermost border of the left and right pedicles at each upper pedicular level from C3 to T1 on transverse CT images by using a picture archiving and communication system (PACS; INFINITT PACS G3, INFINITT Healthcare, Korea) The spinal cord diameter was measured between the left and right outermost distances of the cord at each upper pedicular level, which were almost the same locations used for measuring the spinal canal diameter, from C3 to T1 on transverse MR images by using the PACS.
