Cervical Cord to Canal Diameter Ratio

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

100 patients (50 men and 50 women aged 20 to 70 years old) who visited our hospital and underwent both cervical CT and MRI simultaneously

Exclusion criteria

patients who had a history of cervical spine surgery or cervical cord edema, whose CT or MR images did not include all the cervical vertebrae from C3 to T1,
patients who had at least one missing medical detail such as diagnosis, age, height, or weight.

Treatment and study plan

computed tomography, Magnetic resonance image

Radiation

Investigators measured the cervical cord and canal diameter by using CT and MRI that were previously taken.

Primary outcomes

the cord to canal diameter ratio

Time frame: from December 1, 2020 through study completion, an average of 2 years were investigated retrospectively.

the measurement of the cord to canal diameter ratio, i.e., the cord to epidural space diameter ratio of each cervical vertebral level from the 3rd cervical vertebra (C3) to the 1st thoracic vertebra (T1) in the coronal plane
