【摘要】：目的探討CEUS評價不同時期大鼠肝泡狀棘球蚴病(HAE)血流灌注的價值。方法采用CEUS觀察70只成功感染HAE的大鼠在接種后不同時期(9、28、50周)的血流灌注特征,并與病理結果對照。結果接種9周時55個(55/70,78.57%)病灶表現(xiàn)為高回聲,15個(15/70,21.43%)病灶表現(xiàn)為混合性回聲,病理表現(xiàn)為乳白色單/多囊泡樣結構。隨接種時間的延長(28、50周),病灶最大徑逐漸增大,病灶內部實性成分及鈣化灶逐漸增多,部分病灶可出現(xiàn)液化壞死。鏡下病灶周邊纖維組織逐漸增厚,周邊見微血管聚集區(qū)。接種9周時CEUS顯示病灶呈環(huán)狀強化及分隔樣強化,28周及50周時呈環(huán)狀強化或伴細線樣強化及無強化。CEUS后病灶邊緣增強帶最大寬度與病灶最大徑比值隨接種時間延長而逐漸減小(P=0.02)。結論接種后不同時期大鼠HAE病灶的超聲征象漸趨復雜,壞死區(qū)及鈣化灶增加,CEUS可顯示不同時期病灶周邊及內部的血流灌注特征。
[Abstract]:Objective to evaluate the value of CEUS in evaluating the perfusion of hepatic alveolar echinococcosis (HAE) in rats at different stages. Methods CEUS was used to observe the blood perfusion characteristics of 70 rats successfully infected with HAE at different stages (2850 weeks after inoculation). Results at 9 weeks after inoculation, 55 lesions showed hyperechoic and 15 / 15 / 70 / 70 / 21.43) lesions showed mixed echo, and 55 / 55 / 70 / 78.57) lesions showed hyperechoic, and 15 / 15 / 70 / 70 / 21.43) lesions showed mixed echo. With the extension of inoculation time of 2850 weeks, the maximum diameter of the lesion gradually increased, and the solid composition and calcification of the lesion increased gradually. Liquefaction necrosis may occur in some lesions. The fibrous tissue around the lesion is gradually thickened under microscope. Peripheral microvascular agglomeration. At 9 weeks of inoculation, CEUS showed the lesion as annular enhancement and septoid enhancement at 28 weeks and 50 weeks with ring enhancement or thin line enhancement and no enhancement. CEUS showed the maximum width of the margin enhancement zone and the maximum lesion size after inoculation. The ratio of large diameter to diameter decreased gradually with the time of inoculation. Conclusion the ultrasonic signs of HAE lesions become more and more complicated in different periods after inoculation. Enhanced CEUs in necrotic areas and calcified foci could display the perfusion characteristics around and inside the lesions at different stages.
