The relationship between the MRI findings before surgery and the final depth of tumor invasion. a. Patient No.6. On T2-weighted sagittal images, a small mass of high intensity grew on the anterior lip of the uterine cervix superficially. The stromal tissue was not torn by a tumor. In this case, the depth of invasion was 1.8 mm on the surgical specimen. b. Patient No. 8. On T2-weighted sagittal images, a flat tumor grew on the posterior lip of the cervix. The low intensity of cervical stroma was somewhat irregular. We diagnosed the lesion as invasive carcinoma. In this case, a depth of invasion was 3.1 mm on the surgical specimen. c. Patients No. 9. On T2-weigted sagittal images, the papillary tumor was detected on the cervical os. The stroma of the anterior and posterior lips was torn by a tumor. In this case, the depth of invasion was 9 mm on the surgical specimen.
