In order to reduce the risk of contrast material induced
nephropathy by contrast-enhancement computed tomography
and nephrogenic systemic fibrosis with renal
insufficiency by contrast-enhancement magnetic resonance
imaging have been of increasing concern, this study
aimed to assess the performance of two noninvasive
functional MRI methods, arterial spin-labeling (ASL) and
blood oxygenation level dependent (BOLD) imaging, in
characterizing the blood flow and oxygenation level of
clear cell RCC.The results showed blood flow measured by
ASL and oxygenation level by BOLD had significant
differences between entire tumor and ipsilateral/contralateral
renal cortex.
