Summary

Understanding common sonography artefacts is crucial for accurate diagnosis. This knowledge prevents misinterpreting artefacts as disease and helps detect hidden pathology in ultrasound imaging.

Area of Science:

  • Medical Imaging
  • Diagnostic Ultrasound
  • Radiology

Background:

  • Sonography artefacts can mimic or obscure pathology.
  • Accurate interpretation of ultrasound images requires artefact recognition.

Purpose of the Study:

  • To review common artefacts in sonography.
  • To differentiate artefacts from actual pathology.
  • To discuss artefacts specific to Doppler and contrast-enhanced ultrasound.

Main Methods:

  • Literature review of common sonographic artefacts.
  • Categorization of artefacts based on ultrasound modality (general, Doppler, contrast-enhanced).

Main Results:

  • Identified key artefacts affecting all sonographic examinations.
  • Highlighted artefacts unique to Doppler and contrast ultrasound.
  • Emphasized the importance of artefact recognition for diagnostic accuracy.

Conclusions:

  • A thorough understanding of sonographic artefacts is essential for clinicians.
  • Knowledge of artefacts improves diagnostic precision and patient safety.
  • This review aids in avoiding misdiagnosis and missed pathology in ultrasound.
