We report a new technique for ultrasound-anatomic correlations consisting of dissection of embalmed specimens during ultrasound examination. Our method consists of performing ultrasound during the different stages of dissection. The technique was developed by making observations of selected structures in two embalmed and two non-embalmed cadaver hands. The image quality was subjectively graded by consensus of two investigators, before and after denudation of the selected structures of the hand. As an example, the technique is demonstrated for the flexors at the metacarpophalangeal joint level, the extensor complex at the level of the proximal phalanx, and the dorsal hood of the second to fourth fingers. Before dissection the image quality in fresh specimens was graded moderate, and in embalmed specimens good. After dissection the image quality was good in fresh specimens and excellent in embalmed specimens. Our method is simple and does not require sophisticated material. Our results indicate that embalmed specimens could be better than non-embalmed specimens, because of the presence of artefacts in the non-embalmed specimens (gas deposits). The described methodology can yield excellent results regarding precise identification of different interfaces and structures, as observed at ultrasound.
我们报告了一种用于超声与解剖结构关联的新技术，该技术包括在超声检查过程中对防腐处理后的标本进行解剖。我们的方法是在解剖的不同阶段进行超声检查。该技术是通过对两具防腐处理的尸体手和两具未防腐处理的尸体手的选定结构进行观察而开发的。在对手的选定结构进行剥离前后，由两名研究人员通过共识对手的图像质量进行主观分级。例如，该技术在掌指关节水平的屈肌、近端指骨水平的伸肌复合体以及第二至第四指的背侧腱帽处得到了展示。在解剖前，新鲜标本的图像质量评级为中等，防腐处理后的标本评级为良好。解剖后，新鲜标本的图像质量为良好，防腐处理后的标本为优秀。我们的方法简单，不需要复杂的材料。我们的结果表明，防腐处理后的标本可能比未防腐处理的标本更好，因为未防腐处理的标本中存在伪像（气体沉积）。如在超声检查中观察到的那样，所描述的方法在精确识别不同界面和结构方面可以产生优异的结果。
