Fig. 1From: Evaluation of the cervix tissue homogeneity by ultrasound elastography in infertile women for the prediction of embryo transfer ease: a diagnostic accuracy studyCervical elastography. a Identification of six regions of interest (ROI) in the cervix. The cervical canal is highlighted in yellow, and the internal and external uterine orifice are indicated with the symbol * and # respectively; b Cervical elastography in a normal case. The difference in tissue stiffness is expressed with a color scale. The green spring on the lower right end side is a real-time feedback of the correct performance of the strain image acquisitionBack to article page
