Objectives: The aim of this study was to evaluate the evolution of lumbar disc herniation in patients treated with oriental medicine. Methods: 14patients(15 cases) with lumbar disc herniation proved at MRI(Magnetic resonance imaging) underwent a follow-up MRI study. Follow-up MRI was performed $4{\sim}14$months(mean 7 months) after initial MRI. Results & Conclusions: 1. 13 cases(87%) had reduction of disc herniation. 1 showed no change in amount of disc herniation. 1 had an increase in disc herniation. 2. Comparison initial MRI with follow-up MRI showed that 2 of the herniations decreased between 0% and 25%, 3 decreased between 25% and 50%, 5 decreased between 50% and 75%, 3 decreased between 75% and 100%. The size of the herniation decreased on average by 49% in 14patients(15 cases). 3. On axial images, the proportion of the cross-sectional area of the spinal canal occupied by the herniated disc was 54.41% on the average on the initial scan, 29.65% on the follow-up scan.

Objective : To evaluate the diagnostic value of computed tomography-myelography (CTM) compared to that of magnetic resonance imaging (MRI) in patients with lumbar radiculopathy. Methods : The study included 91 patients presenting with radicular leg pain caused by herniated nucleus pulposus or lateral recess stenosis in the lumbar spine. The degree of nerve root compression on MRI and CTM was classified into four grades. The results of each imaging modality as assessed by two different observers were compared. Visual analog scale score for pain and electromyography result were the clinical parameters used to evaluate the relationships between clinical features and nerve root compression grades on both MRI and CTM. These relationships were quantified by calculating the receiver-operating characteristic curves, and the degree of relationship was compared between MRI and CTM. Results : McNemar's test revealed that the two diagnostic modalities did not show diagnostic concurrence (p<0.0001). Electromyography results did not correlate with grades on either MRI or CTM. The visual analog pain scale score results were correlated better with changes of the grades on CTM than those on MRI (p=0.0007). Conclusion : The present study demonstrates that CTM could better define the pathology of degenerative lumbar spine diseases with radiculopathy than MRI. CTM can be considered as a useful confirmative diagnostic tool when the exact cause of radicular pain in a patient with lumbar radiculopathy cannot be identified by using MRI. However, the invasiveness and potential complications of CTM are still considered to be pending questions to settle.

We aim to monitor vascularization of early bone perfusion following rabbit lumbar intertransverse bone graft fusion surgery using magnetic resonance imaging assessment. Correlation with graft survival status was evaluated by histological method. Experimental animals were randomly divided into three groups and the model was established by operating bilateral lumbar intertransverse bone graft with different types of bone graft substitute material. The lumbar intertransverse area of three groups of rabbits was scanned via MRI. In addition, histological examinations were performed at the $6^{th}$ week after surgery and the quantitative analysis of the osteogenesis in different grafted area was carried out by an image analysis system. The MRI technique can be used for early postoperative evaluation of vascularized bone graft perfusion after transplantation of different bone materials, whereas histological examination allows direct visualization of the osteogenesis process.

Herein, a case of missed upper lumbar disc herniation, diagnosed by thorough neurological examination, digital infrared thermographic imaging[DITI], and repeated magnetic resonance[MR] image study, is reported. A 36-year-old female presented with intractable leg pain on left anterior thigh. Although she underwent lumbar MR image at other hospital, she was misdiagnosed as acute sprain. Neurological examination suggested the possibility of upper lumbar disc herniation, which was confirmed by DITI, MRI, and selective root block. After operation, her leg pain was significantly improved. It should be considered that upper lumbar disc herniation might be misdiagnosed as an acute sprain, as in our case. A high index of suspicion based on thorough neurological examination is most important in such cases. Then, multi-access such as DITI, MR image, and selective block, base on thorough neurological examination, are warranted.

Objective : The purpose of this study was to suggest (diagnostic) criteria for lumbar disc space and see the correlation between lumbar disc space narrowing and the level of HIVD. Methods : We looked at the 113 patients diagnosed disc space narrowing with lumbar x-ray and MRI films who have visited Jaseng Hospital of Oriental Medicine with low back pain in October,2013. The width of lumbar disc space and the severity of Herniated Intervertebral Disc(HIVD) on MRI films were collected and stastically analyzed using one-way ANOVA. Results : In this study, measured value(%) for lumbar disc space of the group diagnosed serious HIVD, such as protrusion, extrusion and migration was significantly decresed compared to the normal group and the bulging group. Conclusion : There was a significant correlation between lumbar disc space narrowing and the level of HIVD.

Objective : To quantitatively evaluate the asymmetry of the multifidus and psoas muscles in unilateral sciatica caused by lumbar disc herniation using magnetic resonance imaging (MRI). Methods : Seventy-six patients who underwent open microdiscectomy for unilateral L5 radiculopathy caused by disc herniation at the L4-5 level were enrolled, of which 39 patients (51.3%) had a symptom duration of 1 month or less (group A), and 37 (48.7%) had a symptom duration of 3 months or more (group B). The cross-sectional areas (CSAs) of the multifidus and psoas muscles were measured at the mid-portion of the L4-5 disc level on axial MRI, and compared between the diseased and normal sides in each group. Results : The mean symptom duration was $0.6{\pm}0.4$ months and $5.4{\pm}2.7$ months for groups A and B, respectively (p<0.001). There were no differences in the demographics between the 2 groups. There was a significant difference in the CSA of the multifidus muscle between the diseased and normal sides (p<0.01) in group B. In contrast, no significant multifidus muscle asymmetry was found in group A. The CSA of the psoas muscle was not affected by disc herniation in either group. Conclusion : The CSA of the multifidus muscle was reduced by lumbar disc herniation when symptom duration was 3 months or more.

Spinal cysticercosis is a very uncommon manifestation of neurocysticercosis which is caused by the larvae of Taenia solium. However, it can develop as a primary infection through blood stream or direct larval migration. It can result in high recurrence and severe neurologic morbidity if not treated appropriately. We report the case of a 43-year-old woman who presented with severe lower back pain and left leg radiating pain in recent 2 weeks. Magnetic resonance image (MRI) of lumbar spine demonstrated extruded disc at the L5-S1 level combined with intradural extramedullary cystic lesion. We performed the open lumbar microdiscectomy (OLM) at L5-S1 on the left with total excision of cystic mass. After surgery, the patient showed an improvement of previous symptoms. Diagnosis was confirmed by histopathological examination as intradural extramedullary cysticercosis. We discuss clinical features, diagnostic screening, and treatment options of spinal cysticercosis.

Study Design: Case report. Objectives: We report 3 cases of loss of disc height after spontaneous regression of a herniated lumbar disc. Summary of Literature Review: Reports of spontaneous regression of a herniated lumbar disc were identified. Materials and Methods: We conservatively treated 3 patients who were diagnosed with a herniated lumbar disc. During outpatient follow-up, radiating pain improved in all patients, but they complained of chronic lower back pain. Magnetic resonance imaging (MRI) was performed for diagnostic purposes. Results: On MRI, spontaneous regression of the herniated lumbar discs was observed, but loss of disc height was also found. Conclusions: A herniated lumbar disc may be a risk factor for loss of disc height. It is important to recognize that a patient with a herniated lumbar disc can struggle with chronic lower back pain even if spontaneous regression of the herniated lumbar disc occurs.
