CEUS

Q: Contrast-enhanced ultrasonography of the Kidney should be avoided in patients with renal insufficiency to avoid Contrast-Induced Nephropathy (CIN).

A) True

B) False

Answer: B

Contrast-enhanced ultrasonography (CEUS) of the kidney doesn't involve Intravenous (IV) dye contrast. Instead, it consists of an IV injection of microbubbles. 

CEUS is very useful in distinguishing vascular from avascular masses. Its specificity is as good as CT or MRI. Another use is in the diagnosis of vesicoureteral reflux.
