From: Breast tumor movements analysis using MRI scans in prone and supine positions

Tumor segmentation in a typical case with stage III invasive ductal carcinoma of the left breast. (A) Axial contrast-enhanced T1 weighted MRI was used for the prone position segmentation. (B) Axial mDIXON MRI was used for supine position segmentation (red line: tumor margin of segmentation mask, and yellow point: center point of tumor).
