Art,

The last one the MRI also suggested accreta & at section, with much elaborate preparation, a thin LUS had the placenta removed easily. The cystoscopy idea is a good one & over the last fifteen years I have had two with negative cystos, true negatives, so this and the flame-like lakes from base to surface of placenta with generous flow are the best findings in my hands.

The MRI may be better able to sort out the layers, but I still do not regard placenta accreta as diagnosable or excludable with a high level of confidence (I have always thought it should be, but it aint).
