Transvaginal sonography assessing endometrial thickness and texture, and MRI measuring junctional zone thickness, can identify uterine factors associated with IVF success and implantation failure.

Abstract

Transvaginal sonographic evaluation of endometrial texture and thickness may be an indicator of the likelihood of achieving pregnancy. Very few pregnancies occur when the endometrial thickness was less than 6 mm. When type C endometrium (multilayered endometrium consisting of prominent outer and midline hyperechogenic lines and inner hypoechogenic regions) greater than or equal to 6 mm thick was seen, the pregnancy rate per embryo transfer is goods. MR imaging is highly accurate in helping to diagnose adenomyosis which is a cause of repeated implantation failures in women undergoing IVF. Furthermore the MRI evaluation of junctional zone thickness (AJZ>7 mm and MJZ>10 mm) is the best negative predictive factor of implantation failure (97%). Thus, we advocate the measurement of junctional zone thickness with MRI in women with 2 consecutive implantation failure following IVF.
