Diffusion-weighted and diffusion-tensor imaging of normal and diseased uterus

Figure 3 A 42-year-old woman with endometrial polyp. A: Hypointense polyp in the endometrial cavity on sagittal T2-weighted image mimicking low grade endometrial carcinoma (arrows); B: Sagittal contrast-enhanced T1-weighted image with fat suppression shows enhancing endometrial polyp (arrows); C: On the axial DWI (b = 1000 s/mm²) image, the mass is hypointense clearly excluding malignancy (arrows); D: Corresponding axial apparent diffusion coefficient (ADC) map. The ADC value within the mass is 1.85 × 10^-3 mm²/s.
