Fig. 10 —Severe standing wave and conductivity artifact in 28-year-old pregnant woman during fetal ultrahigh-field-strength MRI at 3.0 T. Coronal HASTE image shows marked signal loss (long arrows). This artifact is caused by large amount of amniotic fluid and increased size of abdomen, which increase electrical conductivity in field of view. Short thin arrows mark placenta; thick arrows mark fetal torso. (Courtesy of Jones B, Cincinnati, OH)
