This study investigated the diagnostic value of monoexponential, biexponential, and diffusion kurtosis MR imaging (MRI) in differentiating placenta accreta spectrum (PAS) disorders. The results showed that D mean and D max differed significantly among all the studied parameters for differentiating PAS disorders. A combined use of these two parameters yielded an AUC of 0.93 with sensitivity, specificity, and accuracy of 83.08%, 88.89%, and 83.70%, respectively. This suggested the quantitative evaluation of PAS disorders with different DWI models and PAS disorders can be differentiated effectively with the combined use of the different DWI parameters.
