Air bubble artifact reduction in post-mortem whole-brain MRI: the influence of receiver bandwidth
2018
Air bubble artifacts on SWI post-mortem MRI studies may interfere with the detection of cerebral microbleeds. We investigated whether the utilization of a higher receiver bandwidth of 500 Hz/pixel could reduce cortical air bubble artifacts without compromising the detection of cerebral microbleeds in high-field MRI. All microbleeds remained clearly visible whereas a reduction of 17% of the long axis of the “halo” magnitude artifacts was achieved. On corresponding phase images, air bubble artifacts appeared identical.
