Predicting osteoarthritis onset and progression with 3D texture analysis of cartilage MRI DESS:6-year data from osteoarthritis initiative

Autor: Ari Väärälä, Victor Casula, Arttu Peuna, Egor Panfilov, Ali Mobasheri, Marianne Haapea, Eveliina Lammentausta, Miika T. Nieminen

In this study, we developed a gray level co-occurrence matrix-based 3D texture analysis method for dual-echo steady-state (DESS) magnetic resonance (MR) images to be used for knee cartilage analysis in osteoarthritis (OA) studies and use it to study

Autor: Arttu Peuna, Mari Leppävuori, Juha Ojala, Miika T. Nieminen, Jari Jokelainen, Michaela K. Bode, Eveliina Lammentausta

Publikováno v: Journal of Voice. 35:804.e27-804.e42

Summary Objective The aim was to study vocal tract dimensions in four vocal modes – Neutral, Curbing, Overdrive and Edge – from Complete Vocal Technique (CVT) by means of magnetic resonance imaging (MRI). Furthermore, the purpose was to test the

Variable angle gray level co-occurrence matrix analysis of T2 relaxation time maps reveals degenerative changes of cartilage in knee osteoarthritis: Oulu knee osteoarthritis study

Autor: Arttu Peuna, Marianne Haapea, Eveliina Lammentausta, Joonas Hekkala, Jana Podlipská, Simo Saarakkala, Ali Guermazi, Miika T. Nieminen

Publikováno v: Journal of Magnetic Resonance Imaging. 47:1316-1327

BACKGROUND Texture analysis methods based on gray level co-occurrence matrices (GLCM) can be optimized to probe the spatial correspondence information from knee MRI T2 maps and the changes caused by osteoarthritis, and thus possibly leading to a more
