title: [Imaging tests in CKD].
abstract: In chronic kidney disease (CKD), imaging tests are useful to evaluate pathophysiology and in some cases, directly lead to the clinical diagnosis, although histological diagnosis still requires renal biopsy. In addition to use of conventional gray-scale ultrasonography (US) for examination of renal anatomy, duplex Doppler US has also permitted assessment of renal hemodynamics. Magnetic resonance angiography and multi-detector row computed tomography angiography are widely used with a high sensitivity and specificity for the diagnosis of renal artery stenosis. We review the clinical application of such imaging tests in CKD and in addition, emphasize the potentially fatal disorder of nephrogenic systemic fibrosis associated with gadolinium-based contrast media.
