Official Title: Contrast-enhanced vs. B-mode Ultrasound-guided Percutaneous Biopsy of Retroperitoneal Tumors - a Randomized Controlled Trial

Brief Summary: Background: Retroperitoneal tumors are typically large and inhomogeneous, with a variable amount of necrosis within the tumor mass which decreases the diagnostic yield of biopsy (false negative or inadequate).Rationale: Real-time contrast enhancement can highlight the viable tumoral tissue and avoid the necrotic area.Aims: To compare contrast-enhanced ultrasound (CEUS) guidance and conventional (B-mode) ultrasound (US) guidance in terms of diagnostic yield, need for repeat biopsy, and rate of adverse…
