Purpose: The aim of this study was to measure the elasticity of normal placentas using the VirtualTouch quantification (VTQ) technique. Methods: This study was approved by the Institutional Ethics Committee. Fifty randomly selected,healthy pregnant women in their second trimester and 50 randomly selected, healthy pregnantwomen in their third trimester with a single fetus were included, and their placentas underwentVTQ through shear wave velocity (SWV) measurements. The measurements were performed atdifferent locations to sample different areas of the placenta. Measurements were performed 3-4times in each location, the mean shear wave velocities were calculated without the highest andlowest values of measurements in each region, and the results were compared. Results: The SWV of the placenta was 0.983±0.260 m/sec, and the minimal and maximal speedwas 0.63 m/sec and 1.84 m/sec, respectively. There was no significant difference between thesecond and third trimester of VTQ of the placenta in terms of SWV (0.978±0.255 m/sec vs. 0.987±0.266 m/sec, P=0.711). The maternal age between second and third trimester was27.9±4.3 years and 29.2±4.4 years, respectively; there was no significant difference betweenthem (P=0.159). Conclusion: The results of this study show that the SWV of normal placenta tissue is 0.983±0.260m/sec, it has little variation between the second and third trimesters, and the VTQ technique maypotentially play an additional role in placenta evaluation.
