Table 3 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)
