Ultrasound is the imaging modality of choice for characterisation of the open spina bifida spinal lesions. On two and tree-dimensional ultrasound, spina bifida is characterized by: Vertebral defect, splayed vertebral pedicles and disrupted vertebrae. The ultrasound must be performed when a positive alpha-fetoprotein is detected in the triple screening test between the 15th and 20th week of pregnancy to confirm the diagnosis.
