Abstract

Color Doppler Sonography: Device Settings Determine the Quality of Diagnosis and the Occurrence of Artifacts Abstract. The major goal of the ultrasound examination is to find the right diagnosis. The correct setting of the device parameters is crucial for a reliable diagnosis. The examiner's knowledge of possible artifacts is helpful in evaluating the ultrasound images. Artifacts are not only present in B-mode sonography, but also in color Doppler sonography. Terms such as blooming, aliasing and twinkling refer to classic artifacts in color Doppler sonography. The causes of these artifacts and the possibilities of influencing them by device technology are presented and discussed. Exemplary images document the most important artifacts in color Doppler sonography.

Zusammenfassung. Die Diagnose ist das Ziel der Ultraschalluntersuchung. Die korrekte Einstellung der Geräteparameter ist dabei entscheidend für die sichere Diagnose. Die Kenntnis des Untersuchers über mögliche Artefakte ist bei der Beurteilung der Ultraschallbilder hilfreich. Artefakte gibt es nicht nur in der B-Bild-Sonografie, sondern auch in der Doppler-Sonografie. Begriffe wie Blooming, Aliasing und Twinkling bezeichnen klassische Artefakte bei der Farbdoppler-Sonografie. Die Ursachen für die Entstehung und die Möglichkeiten der gerätetechnischen Beeinflussung der Artefakte werden vorgestellt und diskutiert. Beispielhafte Bilder dokumentieren die wichtigsten Artefakte in der Farbdoppler-Sonografie.

Keywords: Aliasing; Artefakt; Blooming; Doppler sonography; Doppler-Sonografie; Sonographie Doppler; Twinkling; aliasing; artefact; artifact; blooming; twinkling.
