Time‐resolved, high‐resolution contrast‐enhanced MR angiography of dialysis shunts using the CENTRA keyhole technique with parallel imaging

To evaluate the use of a dynamic keyhole magnetic resonance angiography (MRA) sequence combined with sensitivity encoding (SENSE) for hemodialysis shunts, because surveillance with conventional contrast‐enhanced MRA (CE‐MRA) is limited by its low temporal resolution, resulting in arteriovenous overlay.
