RESUMO
Objective To analyze the changes of radioactivity of the marginal zone of hepatic alveolar echinococcosis (HAE) before and after the treatment with albendazole liposomes,and to explore the value of 18F-fluorodeoxyglucose (FDG) PET/CT imaging in therapeutic response.Methods From July 2011 to July 2015,37 patients (21 males,16 females;average age (53±12) years) with HAE were selected and underwent 18F-FDG PET/CT imaging before routine medication with albendazole liposomes (10 mg · d-1 · kg-1),and the maximum standardized uptake value (SUVmax) of the margin of lesions was calculated.PET/CT imaging was performed again 6 months later to measure the SUVmax of the marginal lesions.Two-sample t test was used to analyze the data.Results In 37 patients with HAE,SUVmax before treatment was 4.88± 1.86,which was higher than that of 24 patients with reduced lesion size after treatment (3.63± 1.38;t =5.24,P＜ 0.001).Conclusion 18F-FDG PET/CT is useful for evaluating the radioactivity of marginal zone of HAE before and after the treatment with albendazole liposomes,and SUVmax of the marginal zone could be valuable for therapeutic response evaluation.
RESUMO
Objective To study the clinicoradiologic significance of C sign.Methods 773 cases of standard ankle CR radiographs were presented for diagnosis of acute trauma and ankle pain. There were 565 males and 208 females, ages ranged from 10 to 81. There were 630 cases of acute trauma and 143 cases of painful ankle. C sign incidence, C sign figuration, distance of the medial facet of talocalcaneal joint, and the figuration of sustentaculum tali were studied. The relationship between C sign and talocalcaneal coalition was analysed.Results The incidence of C sign was 54.6%(422/773). The female incidence was 61.1%(127/208) ,which was more than that of male(52.2%,295/565)(P
RESUMO
Objective To study the incidence and radiologic findings of calcaneonavicular coalition.Methods CR films of foot andankle in 1361 cases were presented,which were evaluated for acute trauma or chronic pain.There were 588 cases of foot CR and 773 cases of ankle CR,age ranged from 10 years to 91 years(984 cases of 20~40 years).The prevalence of calcaneonavicular coalition was determined and the different significance of both male and female,acute trauma and chronic pain group were analysed.Results In 1361 cases,72 cases of calcaneonavicular coalition(5.3%) were demonstrated,8.7%(47/588)on foot CR films and 3.2%(25/773) on ankle CR films.Calcaneonavicular coalition was more dipicted on foot CR films than on ankle CR films(P0.05).Conclusion The foot CR films is more superexcellent than the ankle CR films on demonstrating calcaneonavicular coalition.
RESUMO
20 years)was 8.60%(48/558) , which was more than that in the second decade of life ( 5.22% ). The incidence of painful group was 9.79%(14/143),which was more than that in foot trauma group 6.78%(40/630).The positive C sign was presented in 61.1%(33/54),posterior-type coalition in 38.9%(21/54),short talar neck sign in 61.1%(33/54)and talar beak sign in 22.2%(12/54). Conclusion The talocalcaneal coalition is a common development abnormality in our country. We must pay attention to the diagnosis of talocalcaneal coalition for painful foot adulthood.
