Desenvolvimento de modelo clínico para predição da possibilidade de identificação da artéria de Adamkiewicz por angiotomografia

Abstract: Resumo Contexto Diferenças morfológicas da artéria de Adamkiewicz (AKA) entre a população portadora e não portadora de doença aórtica têm importância clínica, influenciando as complicações neuroisquêmicas da medula espinhal em procedimentos operatórios. Ainda não é conhecida a correlação entre parâmetros clínicos e a previsibilidade da identificação dessa artéria pela angiotomografia. Objetivo Desenvolver um modelo matemático que, através de parâmetros clínicos correlacionados com aterosclerose, possa prev… Show more

“…23,25 Use of ROC curves has been extended to evaluation of the performance of multivariate models for diagnosis, prognosis, machine learning (e.g., image or voice recognition), and data mining. Recently, Amato et al 26 conducted a cross-sectional study using clinical information and a bank of images from 110 patients who had undergone angiotomography of the aorta to predict identification of the artery of Adamkiewicz. Using multivariate analysis, they constructed a predictive model and evaluated its discriminatory properties using a ROC curve, showing that it enabled correct identification in 61% of the patients using a combination of nine covariates.…”
