Renal artery embolization and ultrasound imaging comparison of TGFPE, PNF10 dispersion, lipiodol and NS. a DSA images of kidney at different points of time after vascular embolization with the TGFPE, PNF10 dispersion, lipiodol and NS. b 3D-CT images of kidney at different points of time after vascular embolization with the TGFPE, PNF10 dispersion, lipiodol and NS. c Bright field and fluorescence scanning of isolated embolized kidney slices within 1 d after vascular embolization (arrow pointing to blood vessel). d Color doppler and B-mode ultrasound images of kidney at different points of time after being embolized by the above embolic material or the injection of NS. e The statistical analysis of B-mode ultrasound images in kidneys at different points of time after being embolized by the above embolic material or the injection of NS. The region surrounded by dotted red line is the embolized kidney. **P < 0.01, ***P < 0.001
