Abstract: ObjectiveTo investigate the value of MRI in the diagnosis of cavernous transformation of the portal vein (CTPV).MethodsPlain MRI,dynamic enhanced and (or) dynamic contrast enhanced magnetic resonance angiography(DCE-MRA) findings in 30 patients of clinical-proved CTPV were retrospectively analyzed.ResultsAmong 30 CTPV patients on plain MRI,obliteration of main and (or) branched portal vein were found,and mass-like or reticular abnormal soft-tissue signals were around the vein,which were produced by collateral vessels.On dynamic enhanced MRI,abnormal hepatic perfusion during arterial phase and abnormal enhanced collateral veins during portal phase could be seen.The above signs became more obvious on DCE-MRA.ConclusionsMRI and DCE-MRA can clearly visualize the anatomical features of CTPV.It is important and can provide the reliable evidence for planning properly therapeutic protocol to recognize and directly evaluate the CTPV.
