Table 2 Application of single-shot fast-field-echo (SSh FFE) sequences (echo-planar imaging)

Parameters

Coronal and sagittal planes; repetition time (TR): 3,000 ms; echo time (TE): shortest; field of view: 230 mm; matrix: 160 × 95; slice thickness: 4 mm; flip angle: 90°; duration: 12 s

Assessment

Foetal skeleton

Clinical application

Facial profile (after GW 28; delineation enhanced because of chemical shift by subcutaneous fat)

Hard palate (cleft palate)

Imaging of normal hyperintense cartilaginous epiphysis and hypointense diaphysis

Bone length and shape (bent bones; skeletal dysplasias)

Ossification disorders (osteogenesis imperfecta)
