Sequence Name	Vendor Specific name	Plane	Fat suppression	Motion compensation	Other relevant parameters	Additional info
1. T2 radial	BLADE/PROPELLER/MultiVane	Coronal oblique/parallel to long axis of uterine corpus	No	Radial acq	Add forced recovery pulse to dec scan time	Consider isotropic variant (SPACE/CUBE/VISTA if pt is cooperative)
2. T2 radial	BLADE/PROPELLER/MultiVane	Axial Sagittal	No	Radial Acq	Add forced recovery pulse to dec scan time	Consider isotropic variant (SPACE/CUBE/VISTA if pt is cooperative)
3. T1 Dixon / T1 in-opp phase		Axial	No	None
4. T1 FS- FSE		Axial	Yes	None		Good for detecting endometrioma
5. DWI		Axial	No	None		Us 3 B- values upto 800
6. T1 FS 3D GRE	VIBE/LAVA/THRIVE	Axial Coronal Sagittal	Yes	BH	Pre and Post contrast	Obtain multiphase axial acq followed by sag/cor delays
Optional sequences
7. T2 3D	SPACE/CUBE/VISTA				Acquired once and reconstructed in all 3 planes
8. bSSFP	TrueFISP/FIESTA/balanced FFE	Sagittal			May replace initial sagittal T2
