The Diagnostic Value Of PET/CT Imaging In Hepatic Alveolar Echinococcosis And Its Biology Boundary

Objective:Analysis the performance of PET/CT about the hepatic alveolar echinococcosis, to improve the understanding of it. Method:The patients who were certified hepatic alveolar echinococcosis,13cases in our hospital (male:5cases,female:8cases,the age is between41±24years old)17lesions in total have taken the PET/CT examinations. All the patients underwent surgical treatment. Makes the analysis to the Performance of PET/CT imaging, and then compared with the pathology.Result:The distribution of radiotracer is Non-uniform in the liver, and sometimes,there is no uptake of radiotracer in the lesion, but around the lesion, the uptake is obvious,so,18F-FDG can draw the biology boundary of the lesion, and then to show the characteristics of radiopharmaceuticals uptake in the boundary, SUVmax values between3.5±1.1, Showing the characteristics of biological activity.2hours later, the delayed phase showed that the uptaking of radiopharmaceuticals is increased, SUVmax values between4.6±0.9, the SUV values of every lesion increase than initial phase. Do the Statistical analysis between the biology boundary of hepatic alveolar echinococcosis and the Pathology, Sensitivity:83.33%(10/12) specificity:60%(3/5), accuracy:76.47%(13/17), positive:83.33%(10/12), negative:60%(3/5)。Conclusion:Not only can be detected the lesion location, shape, number, border, calcification and the surrounding tissue, but also have diagnostic value for the activity characteristics of the lesions、 development process, the prognosis. The diagnosis of around metastases,screening and diagnosis of distal metastasis,to provide earlier and effective diagnostic value.
