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 explore the application value of MRI and CT in the diagnosis of prolapse of lumbar intervertebral disc. Methods 58 cases of patients with lumbar disc herniation in our hospital from September 2011 to September 2013 were selected,and all of them underwent MRI and CT scan. The diagnosis of the two groups were observed and recorded, and the results were compared with the final operation results. ResultsThe MRI and CT findings and the final operation results were compared with available, MRI inspection accuracy rate was significantly higher than that of CT examination, the difference was statistically significant(P0.05). Conclusion CT and MRI each have advantages and disadvantages. Compared with CT, MRI has higher diagnosis rates. Clinical doctors can choose the appropriate method by combining with actual situation, and the combination of CT and MRI are actively recommended to improve the diagnostic accuracy rate.

Objective To observe, analyze and compare the characteristics of CT and MRI images in patients with lumbar disc herniation and the diagnostic value. Methods 105 cases of patients diagnosed as lumbar disc herniation were selected. The earliest visiting time of the patients was in December, 2005, and the latest was in March, 2010. The clinical data of these patients were retrospectively analyzed. All the patients underwent both CT and MRI. The detection results was analyzed and compared between the two methods. Results By MRI, the detection results of 101 cases of patients are accurate; the accuracy rate is as high as 96.1%; by CT examination, the detection results of 95 cases are accurate, the accuracy rate is 90.48%, the difference between them is not statistically significant, P0.05. MRI images mainly show lesion of nucleus pulposus low signal and nucleus pulposus ectopic, CT images mainly show nucleus pulposus fuzzy edge, herniation of the nucleus pulposus, dystopy, acute syndrome and so on. Conclusion Both MRI and CT technology have high value in the diagnosis of lumbar disc herniation. In clinical practice these two methods can be used together so as to improve the accuracy rate of diagnosis.

Objective
To compare the diagnostic value of CT and MRI in the diagnosis of far lateral lumbar disc herniation (FLLDH).
Methods
The CT and MRI imagine data of 34 patients with FLLDH were retrospectively analyzed and compared.
Results
The positive rate of CT in diagnosis FLLDH was 88.24% (30/34), and the positive rate of MRI was 94.12% (32/34). There was no statistical difference (P>0.05). There were no statistical differences in the diagnosis of disease region and image representation between CT and MRI (P>0.05).
Conclusions
There is higher coincidence rate of CT and MRI in the diagnosis of FLLDH, but the two imaging methods have their own advantages and disadvantages. In clinical practice, the two imaging methods can be used to improve the clinical diagnosis rate, and provide a reliable basis for determining the surgical treatment options.

The aim of the study was an assessment of the usefulness of magnetic resonance imaging (MRI), computed tomography (CT), and radiculography (R) in the diagnosis of lumbar discopathy. The accuracy of MRI, CT, and R for the diagnosis of lumbar herniated nucleus pulposus ws compared prospectively in 120 patients, undergoing surgical exploration. MRI was the most accurate test (100%) compared with CT (95%) and R (92.5%). The false positive rate was lowest for MRI (0%), followed by CT (5%) and R (7.5%). MRI proves very favorable compared with other currently available imaging modalities for diagnosis of lumbar herniated nucleus pulposus which allows to differentiate hernia and protrusion. MRI is noninvasive, has no known side effects and no radiation exposure. It is the procedure of choice for the radio-diagnosis of lumbar disc herniations.

The purpose of this study is to determine the value in detecting lateral disc herniation (LDH) which was depicted by myelography, computed tomography and magnetic resonance imaging. We retrospectively reviewed 20 patients presenting LDH with persistent lumbar radiculopathy. Fourteen cases were evaluated with CT scan and 3 were evaluated by MRI and 6 cases were evaluated by lumbar myelography with post-myelographic CT. The most commonly affected level was L5-S1 (70%) in our series. This accounted for the majority of upper lumbar root compression syndromes. Myelography disclosed LDH in three cases presenting with obliteration of the corresponding nerve sheath. Epidural soft tissue lesion encroaching upon extraforaminal or neural foramen was seen 20/20 on CT scans and 2/3 on MRI respectively. Our experience suggests that CT and MRI are more effective than myelography for demonstrating the presence and extent of LDH.

Objective To evaluate the clinical diagnostic value of the 1.5TMRI imaging characteristics of the far lateral lumbar disc herniation(FLLDH)by respective study. Methods To collect 241 cases confirmed to be protrusion of intervertebral disc by surgical operation at Luhe hospital from Jan.2013 to Dec.2014.Among these patients,63 cases are the diagnosis to be FLLDH with totally 73 lesions. According to the 1.5TMRI imaging findings of these patients, the imaging characteristics, concomitant lesions, predilection site and the relationship of typing and ratio are analyzed, thereby estimating the diagnosis value of MRI in FLLDH. Results In 73 lesions of 63 patients diagnosed to be FLLDH, 52 lesions(71.1%) are founded at L4-5 segment and L5-S1 of the spin, 41 lesions(56.2%) are the intervertebral foramen subtype. And, 68 lesions(93.2%) occurred with concomitant bone degeneration, intervertebral disc degeneration. The sensitivity of the MRI diagnostic method in FLLDH is 75.3%, the specificity is 98.1%, the accuracy is 92.2%,the negative predictive value is 93.2%,and the positive predictive value is 92%. Conclusion MRI is a noninvasive imaging method, and can accurately diagnose the far lateral lumbar disc herniation. To analyze the imaging features of FLLDH is significant for guiding clinical diagnosis and treatment.

Objective: To analyze the application value of MRI and CT diagnosis for those with lumbar disc herniation. Methods: The data of 62 patients with LDH treated in our hospital from January 2019 to December 2019 were analyzed retrospectively. All patients were diagnosed as LDH after operation, and 62 patients were treated with MRI and CT. The accuracy of CT and MRI in the diagnosis was analyzed according to the gold standard of operation results. Results: 62 patients were diagnosed as LDH after operation, including 25 cases with intervertebral disc herniation, 12 cases with intervertebral disc prolapse, 8 cases with intervertebral disc nodule, 7 cases with intervertebral disc dissociation as well as 10 cases with intervertebral disc bulge. The accuracy of MRI diagnosis (95.16%) was higher than that of CT (75.81%), and the difference was statistically significant (P<0.05). Conclusion: For the diagnosis of LDH, MRI is more accurate, but CT is faster and cheaper. Both of them have their own advantages and can be chosen clinically according to the actual situation of patients on the basis of ensuring the diagnostic accuracy.

Analysis of computed tomography (CT) of the lumbar spine and myelography in 48 of 52 consecutive patients with the clinical diagnosis of disc herniation, confirmed at surgery, showed CT to be superior to myelography in diagnosis. We suggest that CT should replace myelography in assessing most patients with possible disc herniation.
