Relationship between MRI features and clinical stages of hepatic alveolar echinococcosis / 实用放射学杂志

ABSTRACT

Objective To explore the relationship between conventional MRI characteristics and clinical stage of hepatic alveolar echinococcosis(HAE).Methods 54 patients diagnosed with HAE in our hospital were collected.The characteristics of HAE in conventional MRI were analyzed,and the correlationship among the Kodama classification,the maximum diameter of the lesion and the clinical stage of PNM were compared.Results According to the Kodama classification,the lesions were divided into 5 typesKodama type 1 (2.63%,2/76), Kodama type 2 (18.42%,14/76),Kodama type 3 (51.32%,39/76),Kodama type 4 (26.32%,20/76)and Kodama type 5 (1.32%,1/76).In this study,22.37% (17/76)lesions were at P1 stage,7.89% (6/76)lesions were at P2 stage,60.53% (46/76)lesions were at P3 stage, 9.21% (7/76)lesions were at P4 stage.44.74% (34/76)lesions were at N1 stage.18.42% (14/76)lesions were at M1 stage.P stage and N stage were positively correlated with the maximum diameter of the lesions (P<0.000,r=0.516;P<0.000,r=0.754).Conclusion There is no correlation between the Kodama typing and the maximum diameter of the lesions.P and N staging is positively correlated with the maximum diameter of the lesions.There is no correlation between M staging and the maximum diameter of the lesions.
