ASSESSING ACUTE KIDNEY INJURY RISK FROM CONTRAST: MEHRAN SCORE VS AMERICAN COLLEGE OF RADIOLOGY GUIDELINES

Abstract

Acute kidney injury (AKI) is a sudden decline in kidney function,

leading to impaired waste and electrolyte elimination. What was once called "contrast

induced nephropathy" is now referred to as "contrast-associated Acute kidney injury." A

1983 Harvard study suggested contrast was a leading cause of hospital-acquired AKI,

but recent evidence increasingly challenges this view. Today, several tools are used to

assess AKI risk—this paper compares two of them: the Mehran Score and the American

College of Radiology (ACR) Guidelines.
