Note:—The ⁺ sign indicates that these values were normalized to adjacent WM values. Mean and standard deviation (SD) are given for each structure and each image type. The standard error of the mean can be obtained by dividing each SD by sqrt(10).
Phase is represented in Siemens phase units (SPU) ranging from −4096 to 4096 (−π to π radians). To convert phase to radians, multiply the phase value with π/4096.
nMean indicates normalized mean; nSD = normalized standard deviation; PDW, PD-weighted.
