Fig. 4From: Monoexponential, biexponential and diffusion kurtosis MR imaging models: quantitative biomarkers in the diagnosis of placenta accreta spectrum disordersPAS disorders in a 33-year-old woman with prior cesarean delivery and placenta previa. (a)T2WI(T2 weighted imaging) showed abnormal vascularization of placental bed and abnormal intraplacental vascularity. The accreta lesion was generally iso- to hyperintense on DWI (b), heterogeneously hyperintense on ADC map (c) and hyperintense on eADC map (d) (white arrow). On IVIM(intravoxel incoherent motion) images, the lesions appeared heterogeneously hyperintense on D map (e), heterogeneous on D* map (f) and hypo- to isointense with some areas of hyperintense on f map (g) (white arrow). On DKI (diffusion kurtosis imaging) images, the lesions appeared iso- to hyperintense on MD map (h) and hypointense on MK map (i) (white arrow)Back to article page
