Fig. 1 Images in a 69-year-old woman with endometrial carcinoma (Group 1). (A) Sagittal plane T2-weighted and (B) T1-weighted fat suppressed postcontrast MR images demonstrate a polypoid lesion in the endometrial cavity (arrows on A and B). (C) DWI MR image (reverse image) demonstrates high signal intensity within lesion, which appear as dark area (arrow). (D) ADC map shows that the lesion is hypointense (arrow), which corresponds with low ADC values. Clinical Imaging 2017 41, 86-94DOI: (10.1016/j.clinimag.2016.10.016) Copyright © 2016 Elsevier Inc.

Fig. 2 Images in a 51-year-old woman with endometrial polyp (Group 2). (A) Sagittal plane T2-weighted and (B) T1-weighted fat suppressed postcontrast MR images demonstrate a large lesion filling the endometrial cavity (arrows on A and B). (C) DWI MR image (reverse image) demonstrates that the lesion is isointense with myometrium (arrow). (D) ADC map shows that the lesion is hyperintense (arrow), which corresponds with high ADC values.

Fig. 3 Images in a 47-year-old woman with endometrial hyperplasia (Group 3). (A) Sagittal plane T2-weighted demonstrates moderate endometrial thickness (arrow). (B) DWI MR image (reverse image) demonstrates high signal intensity within endometrium, which appear as dark area (arrow). (C) ADC map shows moderate–high intensity within endometrium (arrow).

Fig. 4 Images in a 50-year-old woman with endometrial thickening due to physiological ethiology (Group 4). (A) Sagittal plane T2-weighted and (B) T1-weighted fat suppressed postcontrast MR images demonstrate prominent endometrial thickness (arrows on A and B). (C) DWI MR image (reverse image) demonstrates high signal intensity within endometrium, which appear as dark area (arrow). (D) ADC map shows that the lesion is hyperintense (arrow), which corresponds with high ADC values. Clinical Imaging 2017 41, 86-94DOI: (10.1016/j.clinimag.2016.10.016) Copyright © 2016 Elsevier Inc.
