The purpose of this study was to correlate lumbosacral spinal ultrasound (LUS) and magnetic resonance imaging (MRI) findings in patients with lumbosacral spinal dysraphisms to evaluate the value of LUS in diagnosis, intraoperative use, and during follow-up of those patients. A total of 24 patients aged up to 6 years old were operated for lumbosacral spinal dysraphisms at the Neurosurgery Department of Zagazig University hospitals during the period from January 2017 to August 2018. All patients were investigated preoperatively, intraoperatively, and on follow-up by LUS to compare the data with preoperative and follow-up MRI of the spine. The median age was 11 months at the time of surgery. The most common anatomical description from the LUS study was thickened filum (18 cases). Using MRI findings as the standard reference, the sensitivity of LUS in detecting a thickened filum was 77.8% preoperatively and 62.5% postoperatively, with a specificity of 100%. The sensitivity and specificity of detecting conus level, solid masses, and cystic masses were 100%. Lumbosacral spinal dysraphisms can be evaluated well by ultrasound imaging in age group up to 6 years old with 100% specificity (true negative) in comparison with MRI.

腰ultrasound部脊柱发育不良的围手术期超声成像与磁共振成像

这项研究的目的是将腰s部脊柱异常症患者的腰s脊柱超声（LUS）和磁共振成像（MRI）结果相关联，以评估LUS在诊断，术中使用和随访期间的价值。在2017年1月至2018年8月期间，在Zagazig大学医院的神经外科进行了总共24例6岁以下的腰ac脊椎功能不全的手术。所有患者均在术前，术中进行了随访，并接受LUS的随访将数据与脊柱的术前和后续MRI进行比较。手术时中位年龄为11个月。LUS研究中最常见的解剖学描述是肥大的子宫（18例）。以MRI检查结果为标准参考，LUS术前检测到增厚的肉sensitivity的敏感性为77.8％，术后为62.5％，特异性为100％。检测圆锥水平，实性肿块和囊性肿块的敏感性和特异性为100％。与MRI相比，通过超声成像可以很好地评估6岁以下年龄组的腰ac部脊柱发育不良，特异性为100％（真阴性）。
