  1. DWI diffusion-weighted imaging, DCE dynamic contrast-enhanced sequence, TE echo time, TR recovery time, FOV field of view, NEX number of excitations, TSE turbo spin echo, EPI echo planar, 3D FS GRE T1 3D fat-saturated gradient-echo T1 sequence
  2. We use the same protocol with different angulation in the axial oblique sequence (perpendicular to the endometrial cavity or cervix) or double oblique sequence (angled in both the sagittal and coronal planes)
  3. %40 dynamics (8 s)
  4. $If the uterus is tilted, we perform double axial plane imaging using sagittal and coronal T2WI sequences
  5. &Single-shot fast-spin echo
