Table 1 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)
