![]() ![]() The proposed technique starts the ML-EM algorithm before the measurement process is completed. An acceleration technique for this algorithm is studied in this paper. The ML-EM algorithm is however also renowned for its long reconstruction times. The Maximum Likelihood-Expectation Maximization ( ML-EM) algorithm is the most popular statistical reconstruction technique for Positron Emission Tomography (PET). On the use of successive data in the ML-EM algorithm in Positron Emission TomographyĮnergy Technology Data Exchange (ETDEWEB)ĭesmedt, P Lemahieu, I [University of Ghent, ELIS Department, SInt-Pietersnieuwstraat 41, B-9000 Gent, (Belgium) Therefore, the ML Flow test could be used in children to aid correct classification of patients for treatment and to The variables that best explained seropositivity are those associated with higher bacterial load. ![]() In the contact group, index case classification, age and type of health service were associated with seropositivity in both analyses. The tree method analysis indicated associations with skin smear, Madrid classification, number of nerves affected and age. Among patients, logistic regression indicated the association of seropositivity with positive slit skin smear and having more than five skin lesions. The test was positive in 21.7% of patients and in 19.7% of contacts. Seropositivity ratios and factors associated with a positive ML Flow were determined. Assim, o teste ML Flow poderia ser utilizado também na infância para ajudar na correta classificação dos pacientes para tratamento e na identificação dos contatos com maior risco de desenvolver hansenÃase.This article presents the results of a cross-sectional study involving 115 newly-diagnosed leprosy patients and 1,011 household contacts, all under the age of 18. ![]() As variáveis que explicaram melhor a soropositividade, em menores de 18 anos, são aquelas associadas à maior carga bacilar. Nos contatos, as duas análises indicaram as mesmas associações: classificação do caso-Ãndice, idade e tipo de serviço de saúde. A análise por árvore de decisão mostrou associação com baciloscopia, classificação de Madri, número de nervos acometidos e idade. Nos pacientes, a regressão logÃstica indicou associação com baciloscopia positiva e número de lesões cutâneas maior que cinco. Observou-se soropositividade em 21,7% dos pacientes e 19,7% dos contatos. Determinaram-se as proporções da soropositividade do ML Flow e fatores associados ao teste positivo. Fatores associados à soropositividade do teste ML Flow em pacientes e contatos de pacientes com hansenÃase menores de 18 anos Factors associated with ML Flow test seropositivity in leprosy patients and household contacts under the age of 18ĭirectory of Open Access Journals (Sweden)įull Text Available Estudo transversal em menores de 18 anos, sendo 115 casos novos de hansenÃase e 1.011 contatos intradomiciliares. ![]()
