Ultrasound-Guided Attenuation Parameter(UGAP)A Valuable Alternative in Differentiation between Renal Angiomyolipoma without Visible Fat and Clear Cell Renal Cell Carcinoma? A Pilot Study
Abstract:Background
To assess the utility of the ultrasound-guided attenuation parameter (UGAP) for distinguishing between and differential diagnosis of renal angiomyolipoma without visible fat (AML.wovf) and clear cell renal cell carcinoma (ccRCC).
Methods
The study included 74 patients with pathological renal tumor (60 ccRCC and 14 AML.wovf from 46 men and 28 women). The UGAP, CT attenuation values, signal intensity (SI), and tumor-to-spleen SI ratios were determined for each renal mass. The mean of five consecutiv… Show more
