title: [Enhanced ultrasonography in the diagnosis of renal tumors].
abstract: At present, we have two methods of enhanced ultrasonography in the diagnosis of renal tumors. One is the ultrasound B-mode imaging enhancement under renal arterial infusion of carbon dioxide microbubbles, a contrast agent for US, and the other is the color Doppler signal enhancement under intra-venous injection of galactose-based echo contrast agent, SH/TA-508. Renal cell carcinoma were imaged from the very beginning of the injection of CO2 through the time complete washout from the kidney. On the other, intra-tumor color Doppler signals were remakedly emphasized after SH/TA-508 administration. Enhanced ultrasonography is useful in the detection of small renal cell carcinoma and differential diagnosis of renal masses.
