Local staging of endometrial carcinoma: role of multidetector CT

The purpose was to evaluate the accuracy of multidetector CT (MDCT) on a 16-row CT scanner in local staging of endometrial carcinoma and more specifically in the assessment of the depth of myometrial invasion and presence of cervical infiltration. This prospective study includes 21 women with newly diagnosed endometrial carcinoma. All CT examinations were performed on a 16-row CT scanner, and the protocol included scanning of the abdomen after intravenous administration of iodinated contrast material, during the portal phase, using a detector collimation of 16×0.75 mm and a pitch of 1.2. Sagittal, parasagittal and oblique reformatted images were evaluated for the depth of myometrial invasion, whether superficial or deep, and the presence of cervical infiltration. Imaging findings were correlated with the histopathologic results. The sensitivity, specificity and accuracy of MDCT in evaluating myometrial invasion were 100%, 80% and 95%, respectively, and for assessing cervical infiltration were 78%, 83% and 81%, respectively. In conclusion, MDCT on a 16-row CT scanner proved accurate in local staging of endometrial carcinoma.
