Table 1. Synopsis of scan time duration and temporal resolution used for the single cardiac phase and CINE T₂ ^* mapping protocols.

	ME	MS	MB CINE	ME CINE	MS CINE
scan duration phantom study	25s	49s	3×81s	121s	241s
scan duration in vivo study	-	24s	3×22s	-	-
acquisition window length	205ms	192ms	36ms	38ms	36ms

The scan duration of MS protocols is doubled versus ME protocols. For in vivo T₂ ^* mapping MS and MB CINE were applied. CINE protocols provided an acquisition window length of about 36 ms, which renders the impact of cardiac motion effects rather low. The acquisition window length is given by the number of k-spaces lines acquired per cardiac cycle times the repetition time.
