title: [Gynecologic tumor].
abstract: The image diagnosis of a gynecologic tumor is progressing with the propagation of magnetic-resonance imaging (MRI), fast X-ray computed tomography (CT), and transvaginal probe. We introduce you the role which an image diagnosis should play in the decision of the therapeutic plan and the evaluation of the therapeutic effect of a uterine cervical cancer, a uterine endometrial cancer, and an ovarian cancer. In a uterine cervical cancer, MRI is useful to grasp the stage and the tumor size, and contributes toward determining a therapeutic plan. In addition, we may guess the response to the therapy, and judge the existence of a residual tumor during or immediately after an irradiation or an intraarterial injection. In a uterine endometrial cancer, MRI will contribute toward demonstrating a cervical invasion and toward assessing a myometrial invasion, therefore may help us to modify a therapeutic plan. To stage an ovarian cancer, it is necessary to visualize a small disseminated lesion. However, as all imaging modalities has a limitation to reveal the small disseminated nodules, they will not replace probe laparotomy. The probability of X-ray CT to take the place of second-look operation by an improvement has been suggested. MRI is poor at the visualization of a dissemination, however it is sometimes helpful for the evaluation of the therapeutic effect of a localizing tumor with demonstrating the changes of the signal intensity. We suppose that also an image diagnosis leaves room for expectation to contribute toward deciding the therapeutic plan of an ovarian cancer.
