Fast 3 T nigral hyperintensity magnetic resonance imaging in Parkinson’s disease
Scientific Reports, 2021 The absence of nigral hyperintensity is a promising MR marker for Parkinson’s disease (PD), but its small size imposes limitations on its routine use. Our aim was to compare Multi Echo Data Image Combination (MEDIC), segmented echo-planar imaging (EPISEG)

A retrospective segmentation analysis of placental volume by magnetic resonance imaging from first trimester to term gestation [PDF]
, 2018 Background Abnormalities of the placenta affect 5–7% of pregnancies. Because disturbances in fetal growth are often preceded by dysfunction of the placenta or attenuation of its normal expansion, placental health warrants careful surveillance. There are
