X-rays:

  2. X-rays clearly show anencephalia, spinal cord hernia, and hydrocephalus.

Fetoscopy :

  1. Fetoscopy provides a visible, real-time image of the embryo, but it has numerous side effects and is only used in rare cases.

Ultrasound:

  1. Ultrasonic examination is used to diagnose a variety of nervous system defects. It also aids in the diagnosis of kidney defects such as polycystic.
