背景：前外侧韧带（ALL）在膝关节内旋中起稳定作用。既往研究报告可使用磁共振成像（MRI）识别ALL;然而，尚无使用超声检查（US）进行此目的的报告。实时虚拟超声（RVS）使用磁导航和计算机软件同步显示实时US和多平面重建MRI图像。本研究旨在探讨超声结合RVS对急性淋巴细胞白血病（ALL）的诊断价值。将医学数字成像通信MRI数据集加载到Hitachi Aloka Preirus中，并在同一监视器上显示US图像。当使用MRI识别出ALL时，冻结监视器以评价ALL。ALL分为股骨、股骨和胫骨部分。结果：MRI可清晰显示ALL的各个部位，并可显示其厚度，以及作为ALL标志的膝下外侧动脉（LIGA）。使用US，在所有受试者中检测到ALL的胫骨部分，在7例受试者中检测到股骨部分;但是，无法识别股骨部分。ALL的平均厚度为1.3 +/- 0.1 mm，并在所有病例中识别出LIGA。结论：ALL的大部分部分可以使用US识别。由于大多数急性淋巴细胞白血病损伤发生在股骨或胫骨部分，超声可能是一个有用的诊断工具，急性淋巴细胞白血病损伤。(C)2015 Elsevier B.

Background: The anterolateral ligament (ALL) functions as a stabilizer in the internal rotation of the knee. Previous studies have reported the ALL can be identified using magnetic resonance imaging (MRI); however, there are no reports on using ultrasonography (US) for this purpose. Real-time virtual sonography (RVS) uses magnetic navigation and computer software for the synchronized display of real-time US and multiplanar reconstruction MRI images. This study investigated the ability of using US with RVS to evaluate the ALL.Methods: Nine healthy subjects were enrolled. The Digital Imaging Communications in Medicine MRI dataset was loaded into the Hitachi Aloka Preirus, and US images were displayed on the same monitor. When the ALL was identified using MRI, the monitor was frozen to evaluate the ALL. The ALL was divided into the femoral, meniscal, and tibial portions. The portions and thickness of the ALLs and the lateral inferior genicular artery (LIGA), a landmark for the ALL, were evaluated.Results: All portions of the ALL could be identified using MRI. Using US, the tibial portion of the ALL was detected in all subjects and the femoral portion was detected in seven subjects; however, the meniscal portions could not be identified. The average ALL thickness as measured by US was 1.3 +/- 0.1 mm and the LIGA was identified in all cases.Conclusions: Most portions of the ALL can be identified using US. As most ALL injuries occur at the femoral or tibial portion, US may be useful as a diagnostic tool for ALL injury. (C) 2015 Elsevier B.V. All rights reserved.
