From: Accelerating spiral tissue phase velocity mapping without affecting peak velocity measurements
R2 (red) and R3 (blue) peak and global TTP values shown as mean +/- SD values over the ten volunteers. A systolic longitudinal (SL) and radial (SR) peak is seen as well as an early diastolic (DL and DR) and atrial systolic (ASL and ASR) peak in each slice. Two systolic circumferential peaks are seen in each slice (C1 and C2) and a third peak is seen at base and apex in early diastole (C3). R2 and R3 show very similar values, indicating that the level of acceleration is not affecting velocity measurements.
