Effect of Radio Frequency Inhomogeneity Correction on the Reproducibility of Intra‐Cranial Volumes Using MR Image Data

摘要: The volumes of total brain, white matter, gray and cerebrospinal fluid in normal volunteers were determined using a supervised nonparametric feature map segmentation dual-contrast MR images after correcting for the radio frequency (RF) inhomogeneity. Reproducibility was evaluated terms inter-observer scan-to-scan variations. A comparison with published results indicates that variabilities determination tissue are substantially reduced following RF inhomogeneity correction.
