L'Hostis F, et al. - In this retrospective study, researchers ascertained if dual-energy CT follow-up of kidney transplant recipients performed with only two contrast-enhanced phases and reconstructed material maps has the same diagnostic efficiency as triphasic conventional CT in detection and characterization of atypical renal cysts and renal masses. As part of their follow-up, 175 renal transplant patients underwent dual-energy CT. One hundred one renal lesions have been detected. According to findings, iodine concentration maps obtained with dual-energy CT perform as well as enhanced images obtained in conventional CT to detect and characterize tissue and atypical cystic renal lesions in kidney transplant recipients. Using this method, especially by avoiding the unenhanced series, could reduce the radiation dose.
