  T2-weighted images are most helpful in distin-guishing simple renal cysts from other lesions. A homogeneous hyperintense lesion with a thin wall on T2-weighted images can be accurately charac-terized as a simple cyst. Septa and solid nodules can be readily seen within cysts on T2-weighted images due to their relatively low signal inten-
