Methodological considerations on segmenting rhabdomyosarcoma with diffusion-weighted imaging—What can we do better?

Abstract

Key points Strategies for segmenting sarcoma tumors vary widely throughout literature. Details of the segmentation strategy are often not reported. Including necrotic or cystic areas in the segmentation affects diffusion measurements. Varying the slice of a single-slice segmentation can drastically impact diffusion measurements.
