Application of T2-w single-shot (SSh) turbo-spin-echo (TSE) sequences
| Parameters | Axial, coronal, and sagittal planes; repetition time (TR): shortest; echo time (TE): 100 ms; TSE factor: 92; field of view: 200–230 mm; matrix: 256 × 153; slice thickness: 3–4 mm; slices: 18; flip angle: 90°; duration: 18.7 s |
| Assessment | Whole body evaluation |
| Clinical application | Head size and shape (microcephaly; encephaloceles) |
| Brain (associated malformations; acquired anomalies) (TE: 140 ms in GW 18–29) | |
| Face and foetal profile (facial clefts) | |
| Orbits (content; interorbital distance) | |
| Teeth buds and hard palate (cleft palate) | |
| External ear size, shape, and position; and fluid-filled inner ears | |
| Thorax shape and lung volume (lung hypoplasia in skeletal dysplasias) | |
| Spine (content/extent of spinal dysraphism) | |
| Arms and legs; hands and feet (size, shape, number of fingers/toes) | |
| Musculature (decreased thickness; fatty atrophy after GW 30) |
