Ultrasound fetal biometry follow the same protocol always. To measure the BPD of a bovine fetus you need to capture clearly the fetal head by ultrasound scanning after that locate the vital land marks such as the falx, thalami and cavum septum pellicidum. After that take your measurements and compare with other parameters to come up with a possible estimated age.

Are you asking what mode or other ultrasound parameters would be best to do this measurement?

Why measure BPD? Why not measure H?

the dimensions of the head will determine the type of probe frequency to use. If you have a machine with harmonics and compound imaging and speckle reduce technology it will improve the visualisation of the end points and anatomy to do the measure

good hunting

I need BPD for my new research in bovine as well as H. measure.

Does your machine use A line or b-mode? If the latter then why is BPD require for your research? Are the charts for dating bovine based on BPD

I agree with Dlama Zira

Thanks for every thing,but I need papers or any researchs about these object in large animals ,especially in bovine.
