ABSTRACT
OBJECTIVE:
The objective was to evaluate the efficacy of diffusion-weighted imaging (DWI) in predicting the development of vascularization in hypovascular hepatocellular lesions (HHLs). MATERIALS ANDMETHODS:
Forty-two HHLs that were diagnosed by computed tomographic (CT) arteriography were evaluated retrospectively. The lesion on DWI was classified as isointense, hypointense, or hyperintense. Follow-up studies that included intravenous dynamic CT or magnetic resonance imaging were performed.RESULTS:
The 730-day cumulative developments of vascularization in hypointense, isointense, and hyperintense lesions were 17%, 30%, and 40%, respectively. The differences among these developments were not statistically significant.CONCLUSION:
The signal intensity on DWI showed no significant difference in the development of vascularization.Palavras-chave
