Intensity ratio curve analysis of small renal masses on T2‐weighted magnetic resonance imaging: Differentiation of fat‐poor angiomyolipoma from renal cell carcinoma

Objectives To assess the diagnostic ability of a pixel intensity‐based analysis in evaluating the magnetic resonance imaging characteristics of small renal masses, especially in differentiating fat‐poor angiomyolipoma from renal cell carcinoma. Methods T2‐weighted images from 121 solid small renal m...
