Overview
CEUS uses intravascular microbubble agents to visualize real time perfusion without ionizing radiation useful for focal lesion characterization.
Technique
Low mechanical index imaging preserves microbubbles. Timing and bolus technique affect enhancement patterns.
Clinical Uses
Liver lesion characterization focal renal and splenic lesions and guidance for ablation.
Limitations and Safety
Contrast contraindications are rare. Operator skill and availability influence use.
