初步探討MRI與PET-CT診斷肝臟泡狀棘球蚴病的應(yīng)用價(jià)值
[Abstract]:Objective: to evaluate the value of magnetic resonance imaging (MRI) and PET-CT in the diagnosis of hepatic alveolar echinococcosis (HAE). Methods: the data of 14 patients with HAE confirmed by surgery and pathology were retrospectively analyzed. 14 patients with HAE were divided into 5 types according to the MRI classification of Kodama, 30 lesions were detected by routine MR scanning and PET-CT examination, the patients were divided into 5 types according to the MRI classification of Kodama, and 30 lesions were detected in 14 patients with HAE. The features of MRI and PET-CT were observed, and the biological activity of HAE lesions was evaluated qualitatively according to the results of MRI and PET-CT. The consistency of MRI and PET-CT results was analyzed and the Kappa value was calculated. Results: (1) MRI findings: the maximum diameter of 30 HAE lesions was 14.59 cm, 1 focus of type 1, 9 lesions of type 2, 10 lesions of type 3, 10 lesions of type 4. (2) PET-CT findings: of the 30 lesions of HAE, there were 1 focus of type 1, 9 lesions of type 2, 10 lesions of type 4. Sixteen lesions showed 18F-deoxyglucose (18F-FDG) uptake in different degrees at the edge of the lesion, of which 15 lesions showed different uptake of 18F-deoxyglucose (18F-FDG) in 1,2,3-type (20 lesions). One of the 10 lesions of type 4 showed high uptake of 18F-deoxyglucose (18F-FDG), and a total of 30 lesions in 14 cases had a good consistency (Kappa=0.59,P0.01) in evaluating the biological activity of the lesions by MRI and PET-CT. Conclusion: the presence or absence of vesicles in MRI images can reflect the biological activity of HAE.
