The cervical spine film generally refers to the X-ray. When looking at the cervical spine X-ray, the first thing to look at is the physiological curvature of the cervical spine, and the normal cervical spine has a physiological curvature. If the physiological scale of the cervical spine becomes straight or disappears, it means that the patient usually lowers his head more, and this condition is mostly seen in people who work long hours and with their heads down, such as students or programmers. Then look at the gap between the cervical spine and the cervical vertebrae. If the gap becomes narrower or smaller, it indicates that a cervical disc herniation may have occurred. Finally, you can look at the cervical spine report, which usually states degenerative changes or other information such as straightening of the physiological curvature of the cervical spine. Since cervical spine x-rays cannot clearly diagnose herniated discs or nerve compression, the data that can be suggested is rather limited and CT or MRI of cervical discs can be done if necessary.
