INTRODUCTION
The aim of this paper is to show how to improve diagnostic accuracy using CDUS and twinkling artifact in patients experiencing discomfort due to the presence of small FBs in the soft tissues not clearly visible at US grayscale examination.
MATERIALS AND METHODS
We enrolled 7 adult patients presenting with small (2-4 mm) superficial FBs located in the subcutaneous and muscle tissues, barely or not detectable on US grayscale. All patients underwent US grayscale and CDUS examinations.
RESULTS
We identified superficial FB with twinkling artifact in all 7 patients. All of these were confirmed to represent foreign bodies after surgical excision.
CONCLUSION
TA is useful in the evaluation of subcutaneous and muscular FBs and provides information on their location, depth and shape, which is useful if surgical excision is required.
简介
本文旨在展示如何使用 CDUS 和闪烁伪像来提高诊断准确性，这些方法适用于因软组织中存在小的 FB 而感到不适的患者，这些 FB 在 US 灰度检查中无法清晰显示。
材料与方法
我们纳入了 7 名成年患者，这些患者的小 FB（2-4 毫米）位于皮下和肌肉组织中，在 US 灰度检查中几乎或无法检测到。所有患者均接受了 US 灰度和 CDUS 检查。
结果
我们在 7 名患者中均发现了具有闪烁伪像的浅表 FB。所有这些 FB 在手术切除后均被证实为异物。
结论
TA 可用于评估皮下和肌肉 FB，并提供有关其位置、深度和形状的信息，如果需要手术切除，这是有用的。
