Interventional ultrasound

Area of Science:

• Medical Imaging
• Minimally Invasive Surgery

Background:

• Interventional ultrasound (US-guided interventions) involves minimally invasive procedures using real-time ultrasound imaging.
• Needle steering devices enhance precision in US-guided interventions.

Purpose of the Study:

• To review the applications and safety of ultrasound-guided interventions.
• To highlight ultrasound's role in diagnosis and therapy.

Main Methods:

• Review of diagnostic and therapeutic procedures guided by ultrasound.
• Inclusion of fine- and coarse-needle biopsies.
• Examination of drainage and catheterization procedures (e.g., nephrostomy, central venous catheterization).
• Assessment of tissue ablation techniques for tumors.

Main Results:

• US-guided biopsies provide a basis for diagnosis and therapy.
• US-guided drainage and catheterization are safe alternatives to conventional methods.
• Interventional ultrasound has low complication (0.19%) and mortality (0.04%) rates.
• Focal tissue ablation methods are under development for liver and prostate tumors.

Conclusions:

• Ultrasound is a safe and cost-effective imaging modality for interventional procedures.
• The range of diagnostic and therapeutic applications for interventional ultrasound is expanding.
