Vascular Color-Coded Duplex Ultrasound in Practice: Artifacts Ultrasound artifacts are technical phenomena which may cause diagnostic mistakes and do not correlate with the real target organ. These optical and acoustic phenomena of color-coded duplex ultrasound are very common in the real world and may lead to misinterpretations and diagnostic errors. The twinkling artifact, for example, imitates high-flow velocities and turbulences, which may lead to the misdiagnosis of a high-grade stenosis or of vascularization. Mirror image artifacts may irritate the sonographer and cause an impression of an additional - really not existing - vessel. The "seagull cry", whose origin is not well understood, is usually found in the region of a high-grade stenosis.
血管彩色编码双功超声在实际应用中的伪像 超声伪像是可能导致诊断错误且与实际目标器官不相关的技术现象。彩色编码双功超声的这些光学和声学现象在现实世界中非常常见，可能会导致误解和诊断错误。例如，闪烁伪像会模拟高流速和湍流，这可能导致对高度狭窄或血管化的误诊。镜像伪像可能会使超声检查者感到困惑，并造成存在额外的——实际上并不存在的——血管的印象。起源尚不清楚的“海鸥叫声”通常出现在高度狭窄区域。
