摘要

目的使用超声诊断（DUS）对 L5 关节旁（L5PI）进行技术描述和验证：使用线性阵列换能器（8-13 MHz）对无症状的 10 岁男性受试者进行 L5/S1 椎面超声诊断扫描；头向长轴滑动以捕捉 L5 上关节突（SAP）和下关节突（IAP）。SAP和IAP之间具有深声影的连续高回声皮质被假定为L5PI。为了证实代表 L5PI 的活体技术，对两个脊柱模型（塑料和人体脊柱）进行了扫描，以验证作者的假设。将金属回形针放在 L5PI 上，然后采集 DUS 图像。最后，对一名已知脊柱溶解的受试者进行成像，并比较 L5PI 的声学外观：结果：用金属回形针在 L5PI 模型上定位的结构与活体 DUS 图像相同。结果：用金属回形针在 L5PI 模型上定位的结构与活体 DUS 图像相当：我们首次报道了使用 DUS 对 L5PI 进行技术描述和验证。

Sonographic evaluation of spondylolysis: technique description and feasibility study of diagnostic ultrasound for the detection of L5 pars interarticularis fractures.

Objective: Technique description and verification of L5 pars interarticularis (L5PI) using diagnostic ultrasound (DUS).

Methods: Asymptomatic 10-year-old male subject was scanned with diagnostic ultrasound applying a linear array transducer (8-13 MHz) over L5/S1 facets; long-axis slide cephalad to capture both superior (SAP) and inferior articulating process (IAP) of L5. Contiguous hyperechoic cortex with deep acoustic shadowing between the SAP and IAP was assumed to be L5PI. To confirm in vivo technique representing L5PI, two spine models (plastic, human spine) were scanned to verify authors' assumption. Metallic paperclip was placed over L5PI then DUS image captured. Lastly, a subject with known spondylolysis was imaged and sonographic appearance of L5PI compared.

Results: The structures localized with the metal paperclip on L5PI models were equivalent to the in vivo DUS image. Spondylolysis demonstrates an abrupt step-off defect at L5PI.

Conclusion: We report the first technique description and verification of the L5PI using DUS.
