AuthorImaging modalitynInclude diabetic women?FindingsComments
Uotila et al. (30)MRI20Yes, 10 type 1 diabetesMRI (10-mm sagittal slices) more accurate than 2D US at predicting BW“Most” fetuses were LGA; imaging completed in under 1 min
Schild et al. (31)3D US125 + 65Unknown3D US formula (thigh volume, upper arm volume, abdominal volume, BPD) more accurate than 2D US at predicting BW13 macrosomic infants, 22 LGA infants
Tukeva et al. (32)MRI8Yes, allMRI measurement (TrueFISP) of fetal shoulder width was closely correlated with actual shoulder widthAll had suspected macrosomia; 7/8 were delivered by cesarean section
Hassibi et al. (33)MRI35UnknownMRI (8-mm axial images) significantly better than 2D US (Hadlock) at predicting BWImaging time was 90 s
Lee et al. (34)3D US100Unknown3D US (fractional thigh volume + AC) significantly better than 2D US at predicting BW
  • 2D, two-dimensional; 3D, three-dimensional; AC, abdominal circumference; BPD, biparietal diameter; BW, birth weight; LGA, large-for-gestational-age; MRI, magnetic resonance imaging; TrueFISP, true fast imaging with steady-state precession; US, ultrasound.
