| 目的 比较MR常规矢状位-轴位扫描与冠状位迭代分解水和脂肪的回声不对称与最小二乘法估计（IDEAL）技术对椎间孔外型腰椎间盘突出症（ELDH）的诊断价值。方法 对手术证实的32例ELDH患者术前行矢状位-轴位和冠状位IDEAL扫描，比较2种技术对椎间盘突出、神经受累、神经受压成角、神经深压迹、神经变细或截断、神经粘连毛糙、神经肿胀的显示情况。结果 2种技术显示椎间盘突出、神经受累、神经周围脂肪减少或消失差异无统计学意义（P>0.05），显示神经成角、神经深压迹、神经变细或截断、神经粘连毛糙、神经肿胀的差异均有统计学意义（P均<0.05）。手术证实32例神经受压情况与IDEAL所见吻合。结论 MR矢状位-轴位和冠状位IDEAL均能诊断ELDH，但对神经受压程度的显示能力不同，冠状位IDEAL明显优于常规矢状位-轴位，可直观、清晰、全面地显示神经的受压情况，是一种有效的影像学检查方法。 |

| Objective To compare the diagnostic value of MR conventional sagittal-axial plane and coronal iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) technique in diagnosis of extraforaminal lumbar disc herniation (ELDH). Methods Totally 32 patients with ELDH confirmed by surgery underwent preoperative MR sagittal-axial plane and coronal IDEAL scanning. Disc herniation, nerve involvement, nerve angle, nerve deep impression, nerve thinning or truncation, nerve adhesion unsmooth and nerve swelling were analyzed between the two methods. Results Disc herniation, nerve involvement and number of reduction or disappearance of surrounding fat had no statistically significant differences between the two methods (all P>0.05), while nerve angle, nerve deep impression, nerve thinning or truncation, nerve adhesion unsmooth and nerve swelling were significantly different between the two methods (all P<0.05). Surgical operation confirmed that 32 patients with nerve compression were consistent with findings by IDEAL. Conclusion MR sagittal-axial plane and coronal IDEAL both can be used to diagnose ELDH, but their display ability of nerve compression is different. Coronal IDEAL is superior to conventional sagittal-axial plane and is an effective imaging method, being able to display nerve compression more intuitively, clearly and comprehensively. |
