Application of thick-slab T2-w imaging
| Parameters | Coronal and sagittal planes; repetition time (TR): 8,000 ms; echo time (TE): 400–800 ms; field of view: 210–320 mm; matrix: 256 × 205; slice thickness: 30–50 mm; flip angle: 90°; up to 15 projections (12°–15° angulation); duration: 8 s |
| Assessment | Foetal proportions and surface, whole foetus from different angles |
| Clinical application | Facial features (micrognathia; dysmorphic features) |
| Intrauterine growth restriction (IUGR) | |
| Dwarfism, mesomelia or rizomelia (skeletal dysplasias) | |
| Extremity positioning (contractures, arthrogryposis) | |
| Extremity thickness (hydrops; subcutaneous oedema; muscle mass) | |
| Limb deformity/deficiency (amniotic bands; clubfeet; skeletal dysplasias) | |
| External masses (extensive lymphangiomas) | |
| Discontinuity of the body surface (omphalocele; spina bifida) |
