Impact of Scan Duration and Sampling Trajectory on Arterial tSNR
| Protocol | Radial | Cartesian | P-Value |
|---|---|---|---|
| 1-shot (2 min 21 s) | 22.2±3.6 | 10.2±3.1 | <0.001 |
| 2-shot (4 min 42 s) | 24.1±3.5 | 10.4±4.7 | <0.001 |
| 3-shot (7 min 3 s) | 25.0±4.1 | 13.8±4.1 | <0.001 |
| All Protocols | 23.8±3.7 | 11.5±4.2 | <0.001 |
Data are from the imaging volunteer group and are presented as mean ± standard deviation. Data obtained from the common carotid artery.
tSNR = temporal signal-to-noise ratio.
