Contrast-enhanced ultrasound for abdominal image-guided procedures.

INTRODUCTION

Since FDA approval for contrast-enhanced ultrasound (CEUS), clinical applications have increased to include diagnostic imaging of hepatic, renal, and other abdominal lesions. The modality has also demonstrated utility in certain image-guided procedures. Intravascular ultrasound contrast agents use microbubbles to improve visibility of solid tumors. Lesions not well seen on grayscale or Doppler ultrasound may become amenable to CEUS-guided biopsy or ablation.

MATERIALS AND

METHODS

This pictorial essay provides eleven examples to illustrate the current use of CEUS in a variety of abdominal image-guided procedures. Hepatic, renal, peritoneal, and soft tissue cases are presented.

CONCLUSION

CEUS can improve visualization and targeting in abdominal image-guided procedures, without nephrotoxicity or radiation exposure.
