Interventional ultrasound techniques

The term interventional ultrasonography is a combination of two contradictory words and, as is often the case, the stronger the opposing forces the more cohesive their bond. So it is with interventional ultrasonography, now that sonography is emerging as one of the essential modalities used in guidance of invasive procedures. Because of advances in aspiration/biopsy techniques and refinements in ultrasound-guidance systems, there has been dramatic, continued growth in the use of interventional ultrasonography. Real-time ultrasonography is used to guide interventional procedures by functioning as a stereotactic instrument that monitors precise needle placement. Further refinements, including compact portable ultrasound systems, allow these invasive procedures to be performed throughout the hospital. The evolution of a major role in guidance of invasive procedures can be better understood by reviewing the advantages of this modality.
