Summary of studies of volumetric assessment of fetal weight
| Author . | Imaging modality . | n . | Include diabetic women? . | Findings . | Comments . |
|---|---|---|---|---|---|
| Uotila et al. (30) | MRI | 20 | Yes, 10 type 1 diabetes | MRI (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 US | 125 + 65 | Unknown | 3D US formula (thigh volume, upper arm volume, abdominal volume, BPD) more accurate than 2D US at predicting BW | 13 macrosomic infants, 22 LGA infants |
| Tukeva et al. (32) | MRI | 8 | Yes, all | MRI measurement (TrueFISP) of fetal shoulder width was closely correlated with actual shoulder width | All had suspected macrosomia; 7/8 were delivered by cesarean section |
| Hassibi et al. (33) | MRI | 35 | Unknown | MRI (8-mm axial images) significantly better than 2D US (Hadlock) at predicting BW | Imaging time was 90 s |
| Lee et al. (34) | 3D US | 100 | Unknown | 3D 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.
