In 18 patients with 19 RO, 9 hypervascularity and hypovascularity was identified in 9 and 10 RO, respectively, in the cortico-medullary phase (CMP). Hypervascular RO showed increased density in the CMP (151.4±38.5 HU) and a gradual wash-out in the nephrographic phase (133.8±34.6 HU) and excretory phase (79±23 HU). Hypovascular RO showed increased density in the CMP (87.8±20.1 UH) and a gradual wash-out in the nephrographic phase (100.3±33 UH) and excretory phase (20.9±86.9 UH).

Abstract
In 18 patients with 19 RO, 9 hypervascularity and hypovascularity was identified in 9 and 10 RO, respectively, in the cortico-medullary phase (CMP). Hypervascular RO showed increased density in the CMP (151.4±38.5 HU) and a gradual wash-out in the nephrographic phase (133.8±34.6 HU) and excretory phase (79±23 HU). Hypovascular RO showed increased density in the CMP (87.8±20.1 UH) and a gradual wash-out in the nephrographic phase (100.3±33 UH) and excretory phase (20.9±86.9 UH).
