Abstract:
Objective To investigate the value of diagnosis and treatment to sequestered lumbar disc herniation by way of CT and MRI.Methods Review the CT and MRI of 55 sequestered lumbar disc herniations.Results The meet ratio of CT is 76.36%,the meet ratio of MRI is 100%.Conclusion MRI is the most effective way to diagnose sequestered lumbar disc herniation.MRI should be choosed when intraspinal spot appear above or under lumbar disc,or when the result of CT is inconsistent with Clinical check.And MRI examination to determine the operative procedures have clear guidance.Keywords:

Objective:To research The clinical significance of diagnosis of lumbar disc disease with CT and MRI.Method:Collected in our hospital in March 2004 has been diagnosed as lumbar disc disease of the 485 cases of lumbar disc disease were retrospectively analyzed CT and MRI data.Results:Data show that young offenders are usually disc disease occurs,compared CT and MRI images in the disc′s performance was no significant difference in diagnosis,CT of the vertebral bone structure of the proliferation and accessories,product gas within the discs,ligament calcification showed advantages;MRI can make the nerve root edema,prominence and relationship with the surrounding structure,space and the dural sac deformation fat full display.Consistent with pathological changes.Conclusion:CT and MRI are complementary to each other.CT combined with clinical examination for the first choice.MRI is the diagnosis of lumbar disc best inspection tools detected in the CT results and discrepancies and should be investigated in further clinical MRI examination.

The purpose of the study was a trial of analysis of the importance of several radiologic methods in the diagnostic management of patients with lumbar disc herniation. On the basis of literature review the high usefulness and value of myelography, CT and MRI in such cases were confirmed.

During March 1986 to September 1988, 52 patients complaining lumbago and/or sciatica diagnosed by CT scanning as herniated lumbar disc were operated upon. The accuracy of CT diagnosis for lumbar disc herniation proved by surgery was 47 cases (90.4%). CT findings and surgical findings did not accord in 5 cases. Of these, some were because of technical problems of the CT scanning and some were faults of surgical technique. The merits and faults of CT scanning for diagnosis of protrusion of lumbar disc and its CT manifestations were discussed.

Thirty-two patients with lumbar disk herniation were studied by comparing MRI with X-P, myelography, CTM, so as to clear part of MRI in lumbar disk herniation. The results in this study proved well the value of MRI. We think that we can take operative steps by MRI only, if MRI findings are in accord with neurological findings, except for cases with MRI findings of multiple disk herniations.

It is very important that occurate diagnosis of the level and location of lumbar disc herniation is made, before surgery is carried out. Recently, the diagnosis of lumbar disc herniation has been made easier with magnetic resonance imaging.We performed a nucleotomy in 22 cases of lumbar disc herniation, which were only diagnosed by magnetic resonance imaging. All cases achieved a good results post-operatively.We concluded that we could operate upon herniated nucleus pulposus diagnosed only by MRI without myelography or CTM. But care must be taken when there is neurological disagreement, spondylosis deformens, central type herniation, old age, or cases requiring re-operation.It is more important to have static rather than dynamic information from MRI, therefore we should perform nucleotomy, rather than instrument surgery.

The diagnostic accuracy of myelography, CT and MRI for the diagnosis of lumbar herniated nucleus pulposus is compared in 32 patients, all of whom underwent surgical exploration. The accuracy rates in these patients were 76.5% for myelography, 85.3% for CT, 79.4% for MRI, and 94.1% for CT and MRI. Although CT and MRI can be viewed as an alternative to the invasive myelography in diagnosing lumbar disk herniation, myelography was more sensitive to change of nerve root. Further advances in MRI technology can be expected to be primary noninvasive diagnostic technique for evaluation of lumbar spine intervertebral disk disease.

ABSTRACT The painful degenerate disc is a recognised cause of low back pain. Magnetic Resonance Imaging (MRI) has now replaced discography in the non‐invasive assessment of disc degeneration. However, the prohibitive capital expense of MRI and the small number of MR units in Australia produce limitations in clinical access. In contrast. Computed Tomography (CT) is readily available and is performed in most patients prior to MRI referral. This prospective study was undertaken to determine whether preliminary CT could offer any information about disc degeneration and so reduce the demand on a MRI scanner. 30 consecutive patients were studied all of whom had both CT and MRI examinations. Of a total 107 discs examined by both techniques, MRI was able to identify 37 degenerate discs. Conclusive evidence of degeneration (i.e. the presence of intervertebral gas) was only seen in 3 discs at CT (1 patient). Of the 29 posterior disc bulges found on CT, all were both bulging and degenerate on MRI. Indications for MRI based on the CT findings are recommended. Using these criteria, 13% (4 patients) of this study group could have avoided an expensive and unnecessary MR investigation. A useful algorithm for the investigation and assessment of patients with chronic low back pain is discussed.

We studied the diagnostic accuracy of magnetic resonance imaging (MRI) and the possibility of its substitution for myelography in 78 patients with lumbar canal stenosis and/or disc herniation, who had myelography and MRI examination. The diagnostic results of the two methods were compared respectively with those of operation, showing no statistical significance (coincidence rate 88.5% vs 92.3%, P greater than 0.05). We conclude that MRI could clearly reveal the pathological changes and anatomical relations of lumbar structures without invasive and radioactive damages, and that with the improvement of operative technique, better understanding of images, and reduction of cost, MRI is likely to replace myelography in the future.

Objective To compare CT and MRI for lumbar disc herniation(LDH) clinical diagnostic value. Methods The clinical data of 62 cases were retrospective analyzed which patients with LDH. The operation results was regarded as the gold standard to analysis the accuracy rate of diagnosis CT and MRI on LDH. Results Was confirmed by operation that 22 cases were lumbar disc herniation, 14 cases were intervertebral disc protrusion, 11 cases were lumbar disc prolapse, 10 cases were intervertebral disc nodules, 5 cases were intervertebral disc free in 62 patients with LDH. The diagnostic accuracy rate of MRI was 95.16%, the diagnostic accuracy rate of CT was 80.65%, the difference was significantly higher(P0.05). Conclusion CT and MRI have their own advantages and disadvantages. The diagnostic accuracy rate of MRI was higher CT. TCM should be a reasonable choice of diagnosis according to the actual situation of patients.
