Which imaging modality may be used to assist retroperitoneal biopsy?

• A. Ultrasound may be used
• B. Monopolar
• C. Bipolar
• D. Laser

Answer: (A)

Guidance during percutaneous retroperitoneal biopsy relies on imaging that lets you see the needle and target in real time. Ultrasound provides real-time visualization of the lesion and surrounding structures, enabling precise needle placement while avoiding vessels and organs. It’s portable, avoids ionizing radiation, and can often be used at the bedside, making it a versatile choice for directing retroperitoneal biopsies when the target is accessible sonographically. The other options are energy delivery devices used for cutting or coagulation during surgery, not imaging modalities, so they don’t provide guidance for a biopsy.
