Comparison of elastographic evaluation in a case with easy, difficult and impossible embryo transfer. a Cervical channel appears red, while the surrounding tissue comprehensive of the six regions of interest (ROI) appears uniformly green with rare blue spots. Embryo Transfer (ET) resulted to be easy; b Cervical canal is not uniformly defined, and surrounding tissue shows a dishomogeneous color pattern. ET resulted to be difficult; c Cervical canal appears to be partially obstructed by a hyperechoic tissue in grey scale image, while elastographic image demonstrates the presence of diffuse tissue dishomogeneity. ET was not feasible, and we had to proceed with a transmiometrial ET
