Abstract Objective To compare acoustic radiation force impulse (ARFI) elastography values and histopathological diagnoses (accreta, increta, percreta) in patients suspected of having abnormal placental invasion (API). Materials methods This prospective study included 54 the third trimester with a history caesarian section (CS) API based on gray scale Doppler ultrasonography (USG) 35 healthy controls. Patients underwent ARFI preoperatively. Elastography measurements fetal maternal sides placenta were compared to histopathology. Results had higher maternal‐side, fetal‐side average ( P = 0.001). Intraoperatively, eight (14.8%) showed cervical canal 46 (85.2%) bladder and/or parametrial invasion. Eight CS + placental‐bed suture, 11 excision lower segment, caesarean‐hysterectomy. Histopathology segment excision/caesarian‐hysterectomy determined 10 (21.7%) accreta, increta 26 (56.6%) percreta cases. highest subgroup. The subgroup than accreta but not significantly different across subgroups > 0.05). cut‐off for average, peripheral central as >0.90, >0.76, >0.98 (m/s) sensitivities 98, 64, 98% specificities 85, 80, 91%, respectively. Conclusion can detect API. However, it cannot determine depth reliably. More studies analyses are warranted reveal its usefulness depth.
