Abstract
Background: To investigate the efficacy of thin-section oblique axial magnetic resonance (MR) images in evaluating cervical invasion by endometrial carcinoma.
Methods: Sixty-seven patients with endometrial carcinoma were evaluated with pathologic correlation. We compared the accuracy in the assessment of cervical invasion by endometrial carcinoma between parasagittal MR images and thin-section oblique axial MR images by using T2-weighted and contrast-enhanced T1-weighted pulse sequences.
Results: Cervical invasion by endometrial carcinoma was confirmed by pathologic examination. Cervical invasion was seen in 16 patients. The accuracy rates of parasagittal T2-weighted images, thin-section oblique axial T2-weighted images, parasagittal contrast-enhanced T1-weighted images, and thin-section oblique axial contrast-enhanced T1-weighted images were 74.7%, 89.5%, 82.0%, and 95.5%, respectively. Statistically significant differences were seen between parasagittal T2-weighted images and thin-section oblique axial T2-weighted images (p= 0.002) and between parasagittal contrast-enhanced T1-weighted images and thin-section oblique axial contrast-enhanced T1-weighted images (p= 0.003).
Conclusion: Thin-section oblique axial MR images are considered to be useful for the assessment of cervical invasion by endometrial carcinoma.
