Half-Fourier acquisition single-shot turbo spin-echo (HASTE) imaging is now widely used for placental and fetal imaging due to its rapidity and its low sensitivity to fetal movement. We aimed to investigate the index of placental dysfunction using HASTE imaging by comparing T2-relaxation time, which is known to be one of the noninvasive biomarkers for IUGR. The placental SIR to the maternal psoas muscle (SIR_{pl/psoas muscle}) showed significant correlation with placental T2 relaxation time. There was possibility that SIR_{pl/psoas muscle} may have relation with fetal well-beings.
