Impact of contrast-enhanced ultrasound in patients with renal function impairment

Figure 2 Patient with grade III chronic renal failure developing acute renal failure after Endovascular aortic repair. A: Color Doppler ultrasound showed avascular kidney; B: Contrast enhanced ultrasound showed enhancing hilar vessels and lack of enhancement of large portions of the cortex (arrowheads) consistent with acute cortical necrosis. The contralateral kidney was normal (not shown).
