Example systems, methods, and apparatus associated with conjugate symmetry in parallel imaging are provided. One example method includes controlling a parallel magnetic resonance imaging (pMRI) apparatus to acquire a first magnetic resonance (MR) signal from a first point in k-space using a phased array of receiving coils. The method also includes identifying a second point in k-space that is related to the first point by a conjugate symmetry relation. The relation may be, for example, a reflection, a rotation, and so on. The method also includes determining a second MR signal associated with the second point based, at least in part, on the first MR signal and the conjugate symmetry relation and then reconstructing an MR image based, at least in part, on both the first MR signal and the second MR signal.
