title: [Small renal cell carcinoma (≤ 4 cm): enhancement patterns on triphasic spiral CT].
abstract: The aim of this study was to define enhancement patterns of small renal cell carcinoma (RCC) (≤4 cm) by triphasic spiral CT. In 24 patients with RCC, hypervascularity and hypovascularity were identified in 12 and 12 RO, respectively, in the cortico-medullary phase (CMP). Hypervascular RCC showed increased density in the CMP (170,7±46,3 UH) and a gradual wash-out in the nephrographic phase (NP) (152,5±41 UH) and pielographic phase (PF) (99,2±38 UH). Hypovascular RCC showed increased density in the CMP (52,9±24,7 UH) and a gradual wash-out in NP (64,5±16,9 UH) and PP phases (55,0±17,3 UH).
