What is the difference between lumbar CT and lumbar orthophoto film?

Answer: If there is lumbar disc herniation, a further CT examination is needed. General x-rays can only roughly look at whether there is hyperplasia in the lumbar spine. However, further examination by CT has mutual influence. 0202 Orthoposition of lumbar spine can diagnose hyperplasia, spondylolisthesis, vertebral tumor, inflammation, tuberculosis, obvious disc herniation and degeneration. 0202 There will be lateral scan during CT scan of lumbar spine. Equivalent to the lumbar lateral position, you will have the diagnosis of the above diseases. If your hospital doesn't have digital X-ray, the lateral bitmap of CT scan will be clearer than lateral X-ray. Then CT will scan three intervertebral discs (usually 3- sacrum of lumbar vertebrae 1, with high incidence). So you will have an understanding of intervertebral disc through CT. You just have a backache. This can't be seen in these two exams. But if these two tests, especially CT, do not find disc herniation, it will be relieved. To sum up, you should choose CT. It is necessary to do it. It doesn't have much effect on the body. Seriously, CT eats a lot of rays, but don't worry. Don't do these two things for your baby unless you are a woman and pregnant. There is no such situation, and it is definitely necessary to have a check-up. Personally, I think it is better to do CT, because CT can also see some things in the positive and lateral position of lumbar spine, such as hyperosteogeny, degeneration, and so on. Moreover, CT can also look at lumbar disc diseases to see if there is disc herniation or protrusion. Whether there is spinal canal stenosis, intervertebral foramen, etc. To sum up, it belongs to CT examination. Although the radiation dose is a little high, it doesn't matter once a year, and there is no harm. Unless you are a woman, want to have a baby or are pregnant.
