A comparison of a mechanical sector and a linear array transducer for ultrasound-guided transvaginal oocyte retrieval (OPU) in the cow
PEJ Bols, J Leroy, T Vanholder, A Van Soom - Theriogenology, 2004 - Elsevier
A comparison was made between a linear array and a mechanical multiple angle sector
(MAP) transducer for ultrasound-guided transvaginal oocyte retrieval (ovum pick-up, OPU) in
the cow. The ovaries of five dairy cows were punctured, in a twice-weekly OPU program
lasting for 4 weeks, using two different 5.0-MHz transducers equipped with an identical
disposable needle-guidance system. Both ovaries were visualized using each transducer
before puncture and the number of follicles with a diameter of less than 5mm (small) and …
