Is Segmental Enhancement Inversion on Enhanced Biphasic MDCT a Reliable Sign for the Noninvasive Diagnosis of Renal Oncocytomas?

Abstract

Contrary to a prior report, we did not find segmental enhancement inversion to be a characteristic enhancement pattern of small renal oncocytomas on biphasic MDCT. We found no specific features on biphasic CT that could be considered reliable and could strongly suggest the diagnosis of renal oncocytoma.
