The labeled cells with superparamagnetic iron oxide (SPIO) can be traced using in vivo MRI. But the labeled cell and hemorrhage could not be clearly distinguished in conventional T2* weighted MRI. By using the positive contrast MRI method, we present the possibility that SPIO-labeled cells were distinguishable from hemorrhage in vitro and in vivo.
