The flat radiograph is an X-ray examination of the spine. Used to diagnose lesions on the spine. X-rays have a certain amount of radiation and need to be mentally prepared. X-ray examination is required for treatment diagnosis, and lead protection products should be worn. Protect the non-illuminated parts, especially the areas sensitive to X-ray reactions such as gonads and thyroids, and wear protective equipment.

Basic Information

The spine film did not show unusual shadows.

Clinical significance

Abnormal results:

The X-ray findings of the tumor in the spinal canal were as follows: 1 positive position showed an increase in pedicle distance; lateral part showed widening of anteroposterior diameter of spinal canal. Its increased range is closely related to the size of the tumor; 2 bone changes in the vertebral body and attachment. The deformation or destruction of the vertebral body is most likely to occur at its trailing edge. Curved forward depression; attachment changes are most common in pedicles and lamina, and can extend to other structures, manifested as pedicle deformation, thinning or even disappearance, absorption and corrosion of lamina; 3 intervertebral foramen Change. It is manifested as the enlargement or destruction of the intervertebral foramen, which is a common sign of nerve root tumors; 4 abnormal calcification in the spinal canal. Found in a small number of meningioma and hemangioblastoma, showing patchy calcification; 5 paravertebral soft tissue block shadow, is the tumor through the intervertebral foramen outward growth.

The lesion of the vertebral body or accessory involves the spinal cord, causing spinal cord compression. Common X-ray manifestations include: 1 traumatic fracture or dislocation of the spine. Vertebral fractures are often seen as vertebral compression or wedge deformation, which can also be a fracture of the vertebral body or attachment. Dislocation is an abnormal arrangement of the position between the vertebral bodies, which can be displaced forward or backward; 2 spinal tuberculosis, showing stenosis of the intervertebral space, with adjacent vertebral bone defects, severe cases can involve several cones, into kyphosis There are often fusiform soft tissue swelling in the paravertebral; 3 congenital malformations of the spine, common spina bifida, vertebral body insufficiency and hemivertebra deformity; 4 spinal tumors, metastasis, chordoma, hemangioma, etc. Bone destruction and hyperplasia. Benign tumors have clear destruction boundaries and often hardened edges; malignant tumors have blurred bone destruction boundaries and irregular shapes, generally do not involve intervertebral discs; 5 spinal degenerative osteoarthrosis and intervertebral disc lesions, visible vertebral bodies, attachments and joints, etc. Hypertrophic hypertrophy, sclerosing hyperplasia and spur formation at the articular surface and vertebral body margin. Disc herniation lesions include degeneration or protrusion. Intervertebral space stenosis is a common sign of disc herniation.

In cervical spondylosis, the X-ray often shows that the cervical lordosis disappears or shows a reverse curve, the intervertebral space narrows, the bone hyperplasia, the oblique slice sometimes shows the bone spur, the intervertebral foramen become smaller, the cervical spinal nerve root, the vertebral artery or the cervical spinal cord Compression caused by upper limb numbness, pain, vertebral artery insufficiency and cervical spinal cord compression symptoms.

In lumbar spondylosis, the lateral position shows lumbar scoliosis. Lateral radiographs show that the lumbar lordosis disappears, the intervertebral space is narrowed, and the adjacent vertebral body has osteophyte hyperplasia, which causes the lumbar spinal nerve root to be compressed to produce lower limbs and pain. And other symptoms.

People who need to be examined have abnormal pain in the waist and neck.

Precautions

Taboo before inspection: X-rays have certain radiation and need to be mentally prepared. X-ray examination is required for treatment diagnosis, and lead protection products should be worn. Protect the non-illuminated parts, especially the areas sensitive to X-ray reactions such as gonads and thyroids, and wear protective equipment.

Requirements for inspection: Obey the doctor's instructions to check. When the X-ray machine is in working condition, the warning indicator on the radiation chamber door will be on. At this time, the patient will wait outside the protective door and do not wait for the film in the inspection room. If the patient does not need special care, the family should not enter the examination room to accompany them to reduce unnecessary radiation.

Inspection process

Enter the X-ray examination room, observe the physiological curvature of the spine, whether the vertebral body has dysplasia, bone destruction, fracture, dislocation, deformation or bone hyperplasia, the shape of the pedicle and the spacing of the arch and root, or the intervertebral foramen Whether there is enlargement, the presence or absence of stenosis of the intervertebral space, the presence or absence of rupture of the lamina and spinous processes, or spina bifida, the destruction of the transverse process of the spine, and the presence or absence of soft tissue shadows at the paravertebral.

Not suitable for the crowd

Taboo people: pregnant women, teenagers.
