Placenta accreta may lead to life-threatening complications and is difficult to distinguish by traditional MRI sequences. In this study, IVIM-based virtual elastography was used for the first time to detect the stiffness of the placenta, and it was found that the virtual (IVIM) stiffness values for the AP-ROIs were mostly higher than those for the NP-ROIs; the IR-ROIs were also significantly higher than the NIR-ROIs. Thus, the implanted regions of the placenta could be significantly stiffer than those of the non-implanted regions. That is helpful for adding a new method for clinical diagnosis of placenta accreta.
