Overview

There are no specific MRI findings associated with acute tubular necrosis. MRI may show alteration in kidney size, outflow obstruction areas that can not be clearly visible on ultrasound.

MRI

  • There are no specific MRI findings associated with acute tubular necrosis. MRI may show alteration in kidney size, outflow obstruction areas that can not be clearly visible on ultrasound.
  • BOLD MRI may be used for detecting blood oxygen delivery to the renal parenchyma and abnormalities associated with perfusion.  Sodium magnetic resonance imaging may detect acute tubular necrosis by corticomedullary sodium gradient abnormalities. However, these tests have limited role in diagnosing acute tubular necrosis.[1][2]
