Diagnóstico Automático de Fraturas do Escafoide em Radiografias do Punho Usando Arquiteturas de Redes Neurais Convolucionais
Resumo
As fraturas do escafoide representam um desafio persistente na radiografia do punho, especialmente em casos não deslocados e em estágios iniciais do trauma. Diante disso, este trabalho propõe um método baseado em Redes Neurais Convolucionais para detecção automática e diagnóstico de fraturas em radiografias do punho. O método proposto emprega Faster R-CNN com backbone ResNet-50 para detecção do escafoide e InceptionResNetV2 para classificação. Resultados preliminares demonstraram bom desempenho, com IoU de 93,1% na detecção e acurácia de 98,22% no diagnóstico. Os achados indicam potencial da abordagem para apoio ao diagnóstico radiográfico.Referências
