How does Whole Spine Dynamic DR enable splice-free whole spine imaging?


Spinal disease is the lesion of bone, intervertebral disc, ligament and muscle of the spine. In China, the number of people suffering from spinal diseases is rising year by year, and presents a trend of low age. Cervical spondylosis, frozen shoulder, lumbar disc herniation, sciatica, scoliosis, ankylosing spondylitis and other bone-type diseases, are related to the spinal column is not correct, of which the incidence of scoliosis more than half of the teenagers, following obesity, myopia, China’s children and adolescents after the health of the third major “killer”. Scoliosis not only affects body shape, but also affects bone growth and physical development in severe cases, and even affects internal organs, as well as pressing on the nerves near the spine and causing pain.

Generally speaking, conventional X-ray is the simplest, most economical and fastest way to evaluate the normal spine or traumatic spinal lesions, and it can provide a complete picture of the bone morphology in the weight-bearing position in the standing position, and the ideal orthopaedic imaging is to perform a full spine imaging in the weight-bearing position. However, at present, traditional X-ray equipment cannot complete the whole spine imaging at one time because of the limitation of imaging area, and can only obtain the full-length image through software splicing after segmental shooting. Although this method solves some problems, it is troublesome and time-consuming for doctors to operate, and it is also easy to produce errors due to splicing, which affects the judgment of the condition; the patient has to repeat the film many times, and receives a large dose of radiation.

Whole Spine Dynamic DR

Perlove has launched an ideal orthopedic imaging solution

Whole Spine Dynamic DR, which performs imaging of the whole spine and both lower extremities under weight-bearing in the standing position. It has the advantages of simple maneuvering, small image magnification and fast process. Patients do not need to take pictures several times, reducing the radiation dose, adding another tool for large-view precision orthopedic diagnosis, such as whole spine photography, double lower extremity photography, trauma emergency, orthopedic correction of the spine, joint replacement, and so on.

Clinical application of whole spine dynamic DR in orthopedic correction

Indications: spinal fracture and dislocation, spinal degeneration such as intervertebral disc degeneration, spinal slippage and scoliosis, spinal tumors, etc.

Description of the disease: Patient, female, 23 years old, scoliosis caused by immune system aberrations

Whole spine dynamic DR photography procedure:

For full spine orthopantomography, the patient stands on a station, with the back and buttocks pressing against the backboard of the station, and the hands naturally drooping and gently holding the handrail to immobilize the body. An opacity scale is placed in the exposure field. The upper and lower boundaries for total spine photography are set, and a total spine image is obtained in 1 exposure. For full spine lateral radiography, one side of the patient’s body is pressed against the backboard of the station, and both hands are raised and gently hold the handrail above the side of the station in the same way as in the orthopedic position.

Whole spine dynamic DR image analysis:

Dynamic DR image of the whole spine

The dotted box shows that the patient’s scoliosis is obvious.

The spine image contains the spine, bilateral shoulders and pelvis. The image structure of cervical spine, thoracic spine, lumbar spine, sacral spine, bilateral shoulders and pelvis reorganization is clear, with high contrast, good alignment, good alignment, and no overlap, omission, or gap in the border area. It can meet the clinical measurement of spine Cobb angle and clinical human body balance line and other indicators, and overall can observe and diagnose the whole spine.

Clinical advantages of Perlove medical whole spine dynamic DR, can through a large field of view imaging, preoperative and postoperative image observation of the patient, non-splicing image can ensure the accuracy of the image data, convenient for the doctor to complete the measurement of the angle of the scoliosis on the workstation, to provide the surgeon with accurate preoperative diagnostic data to improve the success rate of the operation.
