Iodinated contrast
agent (CA) is important for many radiologic and interventional procedures.
However, contrast-induced acute kidney injury (CIAKI) is potentially
life-threatening, especially for patients with impaired renal function, and it has
become one of the leading causes of hospital-acquired acute kidney injury (AKI)[1] . The pathogenesis of CIAKI is not yet fully understood, but the
relevance of renal medullary hypoxia in the pathophysiology of AKI is well
accepted. In recent years, many studies focused on the change of intrarenal oxygenation
and showed renal hypoxia especially in medulla. Blood oxygen level dependent
magnetic resonance imaging (BOLD MRI) is a noninvasive method that can assess
hypoxia by utilizing the endogenous contrast generated by paramagnetic
deoxyhemoglobin[2] .
