In order to evaluate clinical significance of MR signal change within vertebral body marrow, we investigated the relationship between signal change of marrow and duration of low back pain, hight of disc, segmental hypermobility, disc degeneration and degree of disc herniation. We reviewed retrospectively simple radiograph, flexion-extension dynamic radiograph and MR images of the lumber spines(L3-S1) of 100 patients, who underwent discectomy at Ewha Womans University Mokdong Hospital from September 1993 to October 1996. 1) There were Modic type 2 changes in 36 patients of 100 patients(36%) and in 52 segments of 300 segments(17.3%). 2) Average was older in the group with signal change in marrow than in that without signal change. 3) Signal change of vertebral body marrow was not significantly related to duration of low back pain. 4) Decreased disc heght was more frequently found in segments with signal change in marrow than in those without signal chagne. 5) Modic type 2 changes was not related to lumbar segmental hypermobility. 6) Degeneration of disc was more frequently found in segments with signal change in marrow than in those without signal change. 7) Signal change of vertebral body marrow was not directly related to degree of disc herniation. Signal change of vertebral body marrow in MRI was significantly related to age, disc height and degree of disc degeneration, and it suggests that the marrow change can be induced by response of vertebral body to the changed mechanical environment, which is due to long-standing disc degeneration.

The purpose of this study is the evaluate the diagnostic accuracy of MRI, frequent location of injury site and injury type in meniscal injury, retrospective review of false positive cases. From September 193 to January 1997 in our hospital, we analyzed a hundred cases of meniscal injury suggested by MRI. And we tried to correct operatively in meniscal injury by arthroscopic or open method of operation. 1)Diagnostic accuracy of MRI was 90% 2)Most common site of meniscal injury was medial meniscus posterior horn(54.4%). 3)Most common injury type was Bucket handle tearing(34.4%). 4)Cause of pitfall in false positive case was most common popliteal tendon sheath(30%). MRI was effective method on diagnosis of meniscus injury and most common injury was medial meniscus posterior horn, And diagnostic fault was caused by popliteal tendon sheath, lateral inferior genicular artery, truncation artifect, meniscofemoral ligament, transverse geniculate ligament.

There have been many recent advances in the clinical and basic sciences concerring the causeand cure of back pain and sciatica. Pain drawings has improved our diagnostic acumen and clinical evaluation in same speed ofmodern diagnositic equipment such as magnetic resonance imaging(MRI). Adequate pain drawings obtained from 100 patients who was treated for a low back disorder from October 1993 to September 1994. An initial dignostic impression was made at a glance over the pain drawing into five diagnostic group and the results were compared with the final diagnosis after treatment with magnetic resonance image(MRI). One helpful strategy in diagnosing cause of back and leg pain syndrome is to assign patientsto one of five diagnostic groups. These are (1) benign etiologies (2) radicalopathy from herniated disk (3) radicalopathy seconday to spinal stenosis (4) serious underlying disorders and (5)behavioral disorders. The initial impressions were 7 benign back pains, 55 disc herniation, 20 spinal stenosis, 15significant underlying disorder and 3 psycogenic back pain. The final diagnosis were 61 disc herniation, 17 spinal stenosis, 12 underlying disease, 7 degenertative disease, 3 psychogenic disorder. Concerning the disc herniation, spinal stenosis, psychogenic disorder there were significant relationship between the initial impression and the final diagnosis. Pain drawings afford an important clue to disc herniation, psycogenic disorder in the assessment of back pain.
