2800 renal transplants are carried out annually in the UK and it is standard practice to perform a Tc-DTPA renogram examination after surgery to check perfusion. This provides some functional information but suffers from low spatial resolution, is lengthy, immobile and costly and uses ionizing radiation. We surmised that contrast-enhanced ultrasound (CEUS) would provide an accurate alternative with increased speed, resolution (temporal and spatial), cost efficiency and safety. ⋯ CEUS will detect perfusion defects seen with Tc-DTPA and due to increased spatial and temporal resolution and multiple scanning angles, will detect further perfusion defects not seen on Tc-DTPA. 3 D CEUS is useful in the quantification of perfusion defects. CEUS is an accurate examination for detecting renal transplant perfusion defects and will detect significantly more defects than DTPA.
