腰椎间盘脱出的诊断在C T闻世以前,常常是根据临床症状和X线平片表现,提出疑似诊断。最终通过髓核造影或椎管造影予以诊断。因此给病人增加许多痛苦,而多不被病人所接受。近年来,由于C T的广泛应用,已证明C T不仅是一种非侵入性的检查方法,并且因具有较高的对比分辨率及空间分辨率,可以直接显示腰椎间盘脱出和膨突,从而避免了椎管造影等检查方法,大大减轻和消除了病人的检查痛苦,因此C T实 Before the diagnosis of lumbar disc prolapse in C T before the news, often based on clinical symptoms and X-ray findings, the proposed diagnosis. Finally by nucleus radiography or spinal angiography to be diagnosed. So to the patient to increase a lot of pain, but not much to be accepted by the patient. In recent years, due to the wide application of CT, it has been proved that CT is not only a noninvasive examination method, but also has the advantages of high contrast resolution and spatial resolution to directly display prolapse and lumbar disc prolapse, thus avoiding Spinal angiography and other inspection methods, greatly reducing and eliminating the pain of the patient’s examination, so CT
