Abstract:
Objective To evaluate the image quality of dynamic three-dimensional contrast enhanced ultrasonography(3D-CEUS) in liver tumors.Methods Twenty-five patients were examed with 2D-CEUS and dynamic 3D-CEUS.Contrast-enhanced computed tomography or magnetic resonance imaging(CECT/MRI) were performed early or late.Two readers reviewed the images of both modalities and graded the images according to diagnostic criteria as follows:tumor blood fusion in arterial phase(unclear-score 0,moderate-score 1,clear-score 2),tumor boundry and relationship with periphery tissues (unclear score 0,moderate-score 1,clear-score 2).The concordance between the two modalities for showing liver tumors was evaluated by Kappa test.Results Twenty-three of 25 danymic 3D-CEUS were displayed successfully versus total objects in CECT/ MRI.Among them,for showing blood fusion,16 lesions scored 2,7 lesions scored 1,2 lesions scored 0 in danymic 3D-CEUS,meanwhile 18 lesions scored 2,7 lesions scored 1,0 lesion scored 0 in CECT/MRI,the Kappa value was 0.65.For showing tumor boundry and relationship with peripherytissues,16 lesions scored 2,7 lesions scored 1,2 lesions scored 0 in danymic 3D-CEUS,meanwhile 21 lesions scored 2,4 lesions scored 1,0 lesion scored 0 in CECT/MRI,the Kappa value was 0.52.Conclusions Danymic 3D-CEUS was shown to be useful for displaying tumor blood fusion,boundry and relationship with periphery tissues in single liver tuomor,the concordance between dynamic CEUS and CECT/MRI for single liver tuomor was fair.For huge liver tumor and multi-tumors,3D-CEUS can not give overall information.
