Abstract: Objective To observe the value of susceptibility weighted imaging(SWI)based on 5.0T MRI for diagnosing hepatocellular carcinoma(HCC)complicated with vein tumor thrombi.Methods Totally 63 HCC patients were retrospectively enrolled,among them 17 complicated with vein tumor thrombi.The efficacy of 5.0T SWI for detecting vein tumor thrombus was observed,and the image quality were compared between 5.0T and 3.0T.Results 5.0T SWI displayed vein tumor thrombi in 16 cases,except for 1 case with vein tumor thrombi in the upper segment of the left lateral lobe of the left portal vein.The liver edge score,overall image quality score,signal-to-noise ratio and contrast-to-noise ratio of portal venous phase and hepatobiliary phase in 5.0T enhanced MRI were all higher than those in 3.0T(all P＜0.05).Conclusion 5.0T SWI was helpful for diagnosing HCC complicated with vein tumor thrombi.
