Low-contrast dose protection protocol for diagnostic computed tomography in patients at high-risk for contrast-induced nephropathy.

Objective: To evaluate the safety of a low-contrast dose computed tomography (CT) protocol for patients with renal insufficiency for contrast-induced nephropathy.

Methods: One hundred forty-three patients with renal insufficiency who underwent low-contrast dose-enhanced abdominal CT were reviewed. Another group of 327 patients who received unenhanced CT was reviewed as a control group.
