From: 1141 Can every other heart-beat acquisition be better for the same breath-hold interval in MR tagging sequences?

Figure 3

SNR gains of every other heart-beat acquisition over every heart-beat acquisition for different last flip angle. 20 cardiac phase images were acquired with temporal resolution of 20 ms and one breath-hold scar time of 17 sec. The every heartbeart acquisition consists of 16 spiral with spiral window of 8 ms. (a) In phantom, using the two maneuvers. The solid line represents the gain using the maneuver of doubling the acquisition time (the acquisition consist of 8 spirals with spiral window of 16 ms) while the dotted line shows the gain for the maneuver of using multishot acquisition with factor = 2 (16 spirals with spiral window of 8 ms). (b) In vivo, the bars represent =/- two standard deviation from the mean value of the SNR gain.
