Examples of SWI and QSM Protocols for the Brain

Field	Recon	Resolution (mm³)	Flip angle	TE1 (msec)	TR (msec)	# echo
1.5 T	SWI	0.8 × 0.8 × 2	20°	40	50	1
	QSM	0.8 × 0.8 × 2	30°	Min	58	Multi
3.0 T	SWI	0.8 × 0.8 × 2	15°	20	28	1
	QSM	0.8 × 0.8 × 2	12°	Min	40	Multi
7.0 T	SWI	0.3 × 0.3 × 1.2	15°	15	28	1
	QSM	0.8 × 0.8 × 0.8	8°	Min	34	Multi

These sequence parameters are not intended as general “recommendations.” Rather, they serve to illustrate parameter examples that produce good SWI and QSM results. The parameters should be modified for different purposes; for example, multiple echoes can also be acquired for SWI.
