椎间盘造影术是一项诊断性手术。用于明确疼痛是否源于椎间盘。通过X线透视定位，将针穿到椎间盘中央，注射造影剂，看看是否诱发出与原有症状相似的疼痛，并用X线及CT检查造影剂扩散的位置和形状，了解椎间盘是否破裂，破裂的大小，综合分析后得出结论，以便制定进一步治疗计划。

A Patient's Guide To Discography
椎间盘造影病人指南
Discography is a diagnostic procedure to help determining the source of back or neck pain.
椎间盘造影术是用于帮助明确腰痛或颈痛原因的诊断性操作。
Intervertebral Discs act as cushions located between series of bones called vertebrae, that make up the spine. The discs, act as shock-absorbers between the bones while providing stability and allowing movement. The discs are made up of strong connective tissue. The tough outer layer is called the annulus fibrosis, the center of each disc, the nucleus pulposus is gel-like at it's normal state.
脊柱由称为椎体的一系列骨头组成。椎间盘充当这些骨头之间的垫片，就象减震器，为脊柱提供稳定，方便脊柱活动。椎间盘由坚韧的结缔组织构成。其外层称为纤维环，每个椎间盘的中心，称为髓核，正常状态下呈胶冻状。
With age, discs loose water content, and become more nerrow, less flexible and less active as cushions between vertebrae. As the discs deteriorates, the outer layer can weaken and tear. A herniated disc occurs when the outer layer raptures and the inner portion leaks out. If the disc travels into the spinal canal, irritation and pressure on the spinal cord or nerves results in pain.
随着年龄的增长，椎间盘水份丢失变窄，弹性降低，作为椎体间的垫片的性能下降。随着椎间盘的退化，外层纤维环会变弱并撕裂。当外层破裂，内容物泄漏，就发生椎间盘疝出。如果椎间盘游离进入椎管，棘激、压迫脊髓或神经，会导致疼痛。
Discs heal slowly, during which time new nerve endings may form in raptured areas. When the discs contract the nerve endings, a chemical reaction takes place, causing irritation and pain.
椎间盘愈合缓慢，在此过程中，新的神经末梢长入破裂区域。当椎间盘与神经末梢相遇，发生化学反应，引起激惹和疼痛。
These problems can cause neck or back pain, burning or tingling sensations, numbness, weakness, and pain. Depending on the location of the disc along the spine, your symptoms may spread to your arms or legs.
这些病变会引起颈痛或腰痛，出现烧灼或针刺感、麻木、乏力以及疼痛。根据椎间盘所在脊柱的节段，症状会扩散到上肢或下肢。
There are many methods of treating disc pain. But if treatment is unsuccessful after a period of time, a discography may be ordered to determinine the exact disc that is creating the problem, to formulate a more appropriate treatment plan.
治疗椎间盘源性疼痛的方法很多，但如果经过一段时间治疗未起效，可能需要进行椎间盘造影以明确引起症状具体是哪个椎间盘，以制订更合适的治疗计划。
On the day of your procedure, you will be asked not to take any pain medication. To begin the out-patient procedure, you will be positioned lying face-down. The affected area will be sterilized and numbed with an anesthetic. You will receive relaxation medicine and antibiotics before your procedure.
在手术当天，避免使用止痛药。开始这个门诊手术前，您会被放置于脸朝下的俯卧位。受累区域皮肤消毒并用麻醉药使之麻木。术前可能使用镇静药或抗生素。
Your doctor will use a live X-ray to carefully insert and guide a needle to the outer layer of the suspected disc. Next, a second needle is moved through the first one, and guided to the center of the disc. If more than one disc is suspected, this process is repeated.
您的医生会使用动态X线，引导将针小心穿入到可疑椎间盘的外层。然后，通过第一根针插入第二根针，并引导到椎间盘的中央。如果疑及更多椎间盘，则重复上述过程。
After the second needle is positioned, contrast dye is injected. The contrast dye may cause temporary pain. You will be asked to rate your pain and asked if the pain is similar to that of your symptoms. If more than one disc is suspected, contrast dye is injected at each one. And then the needles are removed.
当第二根针穿刺到位后，注入对比造影剂。对比造影剂可能引起短暂的疼痛。医生会让您评估疼痛，是否与原先的症状相似。如果疑及更多的椎间盘，则逐个注入对比造影剂。最后将针拔除。
The next step in the discography uses an X-ray to show where the contrast dye has spread. The pattern of dye within the disc can help determine if the disc is abnormal. At which time, a computed tomography (CT) scan may be used to show more detail about the extent of the rupture or tear pattern, as well as the size and shape of the disc.
下一步，用X线显露造影剂扩散到何处。造影剂在椎间盘内的扩散形式有助于确定这个椎间盘是否存在异常。此时，也可用计算机辅助断层（CT）扫描更详细地显示椎间盘破裂的范围及撕裂的形状以及椎间盘的大小和形状。
You will be monitored for about 45 minutes before you can return home. Another person should drive you home, if you received relaxation medication. Your doctor will prescribe medication to ease the temporary pain from the procedure.
在您能回家之前，会被监护约45分钟。如果您接受了镇静药物，您应该让别人开车送您回家。医生会为您开具药物来缓解手术引起的疼痛。
A discography is not a treatment, but diagnostic tool to determine the sourse of pain. Your doctor will discuss your result and options for future treatment after you receive your diagnosis.
椎间盘造影术不是治疗手段，而是诊断手段，用于明确引起疼痛的原因。您的医生会在您得到诊断之后与您讨论结论及后续的治疗选择。
