Valid preoperative imaging procedures are important in the diagnosis of soft-tissue tumours of the extremities due to their potential malignancy. The value of ultrasound regarding these tumours is still under controversial discussion. Hence, it was the aim of this retrospective study to examine the value of ultrasound in respect of these particular problems. Therefore, in 20 cases ultrasonography was compared with intraoperative findings and other imaging techniques. Finally ultrasonography is merely an "adjuvant" diagnostic procedure, because it does not precisely outline the anatomical topography is incomplete and differentiation from neural and vascular structures is not possible in all cases. In contrast, ultrasonographic description of the size of tumours demonstrates a good correlation when compared with intraoperative findings. In addition, ultrasound examination can help to improve preoperative diagnosis in cases when imaging with MRI and CT is disturbed due to already implanted metallic endoprosthetic components.
由于存在潜在恶性风险，有效的术前成像程序对于诊断四肢软组织肿瘤至关重要。超声对于这些肿瘤的价值仍存在争议。因此，本回顾性研究的目的是探讨超声在这些特定问题上的价值。为此，对20例患者的超声检查结果与术中发现及其他成像技术进行了比较。最后得出结论，超声仅仅是一种“辅助”诊断程序，因为它不能精确勾勒出解剖结构，信息不完整，且并非在所有情况下都能区分神经和血管结构。相比之下，超声对肿瘤大小的描述与术中发现具有良好的相关性。此外，当由于已经植入金属假体部件而导致MRI和CT成像受到干扰时，超声检查有助于改善术前诊断。
