How To Measure Fetal Biparietal Diameter On Ultrasound | BPD Measurements | Biometric Parameters USG
- Obtain a mid-sagittal view of the fetal head, then rotate the transducer 90 degrees to achieve an axial (transverse) plane at the level of the thalami and cavum septum pellucidum.
- Landmarks: The ideal plane for BPD measurement will have: The midline falx, both thalami, cavum septum pellucidum, and symmetrical shape of the head.
- Calipers are placed on the outer aspect of the near parietal bone and on the inner aspect of the far parietal bone.
Repeat the measurement a few times to ensure consistency.
