OBJECTIVE Our primary aim was to investigate if women with placenta accreta can be differentiated with women without using IVIM quantitative assessment of the placental perfusion. A second aim was to investigate if IVIM parameters could be used to differentiate placenta accreta from increta. METHODS The study population included 17 patients with placenta accreta, 29 patients with placenta increta and 16 patients without placenta accreta between 28 + 0 to 41 + 6 weeks. All women underwent a MRI examination including an IVIM sequence at 1.5 T. The perfusion fraction (f), pseudodiffusion coefficient (D*) and standard diffusion coefficient (D) were calculated. Results Women with placenta accreta and increta had a smaller placenta perfusion fraction (P < 0.05) than patients without placenta accreta, placental perfusion fraction didn't differ between placenta accreta and increta (p > 0.05). Differences of D and D* in three groups showed no statistical significance (p > 0.05). CONCLUSION Placenta accreta and increta differ in placental perfusion fraction from women without the disease. The perfusion fraction can be used as a feasible index to evaluate placenta perfusion.
