High sensitivity MR acoustic radiation force imaging using transition band balanced steady‐state free precession

MR acoustic radiation force imaging (MR‐ARFI) provides a method to visualize the focal spot of a focused ultrasound (FUS) beam without introducing a significant temperature rise. With conventional spoiled MR‐ARFI pulse sequences, the ARFI phase always equals the motion‐encoded phase. In this work, MR‐ARFI using transition band balanced steady‐state free precession (bSSFP) is presented, which improves the sensitivity of MR‐ARFI with high acquisition speed.
