Imagens com baixo SNR apresentam frequentemente artefactos de ru\u00eddo que podem ocultar caracter\u00edsticas importantes, reduzindo a precis\u00e3o diagn\u00f3stica.

Utiliza t\u00e9cnicas avan\u00e7adas para reduzir o ru\u00eddo, preservando simultaneamente caracter\u00edsticas essenciais da imagem.
