Abstract
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.
