Can IVIM MRI be used to differentiate patients with placenta accreta spectrum disorders?
Objective The primary aim was to investigate whether the parameters from IVIM can be used to differentiate patients with PAS disorders complicating placenta previa. A second aim was to determine whether these parameters can be used to differentiate different categories of PAS disorders complicating placenta previa.
Methods All the patients had placenta previa, including 16 patients with placenta accreta, 51 patients with increta, 8 patients with percreta and 24 patients without PAS disorders between 28+0 and 39+6 weeks. All women underwent MRI examination including an IVIM sequence at 1.5T scanner. The perfusion fraction(f), pseudodiffusion coefficient (D*) and standard diffusion coefficient(D) were calculated.
Results Women with PAS disorders had a higher perfusion fraction (P<0.05) than women without the disease. Multiple comparisons showed perfusion fraction in patients without PAS disorders was significantly lower than in patients with placenta accreta and percreta(P<0.05), but was not lower than in patients with increta(p>0.05). Conclusion Patients with placenta accreta and percreta differ in placental perfusion fraction from women with increta and without PAS disorders. The perfusion fraction can be used as a reliable index to evaluate placenta perfusion fraction.
