内容記述(抄録等)Objective: To evaluate whether 3D magnetic resonance myelography (MRmyelography) using fat-suppressed-three dimensional coherent oscillatory state acquisition for the manipulation of the image contrast (FS 3D-COSMIC) sequence has additional diagnostic value in the diagnosis of lumbar canal stenosis. Materials and Methods: The patient population consisted of 30 patients who were seen for the diagnosis of lumbar canal stenosis. The lumbar segments were divided into 15 groups, from L1-L2 to L5-S1; right, middle and left. Of all segments examined (450 segments), 180 segments confirmed to have stenosis by surgery were included in this study. The sensitivities, specificities, and accuracies of observer for diagnosing lumbar canal stenosis of the routine MRI + MR myelograpy were compared with those of the routine MRI alone. In addition, receiver operating characteristic analysis was performed. Results: In all segments, both the sensitivity, accuracy and Az value were significantly higher for the routine MRI + MR myelography than for the routine MRI alone (P< 0.05). Conclusion: The addition of MR myelography using the FS 3D-COSMIC sequence to routine MR imaging may be useful for evaluating lumbar canal stenosis; especially, the technique may contribute to improving the sensitivity for the diagnosis of lumbar canal stenosis.
