Abstract
Objective To assess the values of diffusion weighted imaging and contrast-enhanced magnetic resonance imaging (MRI) in the evaluation of early endometrial cancer. Methods We retrospectively analyzed the imaging data of 27 patients with pathologically confirmed stage I - II endometrial cancer. These patients received pelvic magnetic resonance imaging, diffusion weighted imaging with apparent diffusion coefficient-T2 weighted imaging fusion images ( ADC-T2WI) , and Tl weighted imaging (T1WI) of contrast-enhanced scan sequence. The accuracies of these image modes were analyzed and compared. Results The accuracy of routine pelvic MRI scan, diffusion weighted imaging with ADC-T2WI fusion images, and T1WI of contrast-enhanced scan for the early diagnosis of endometrial cancer was 66. 7% , 85. 2% , and 92. 5% , respectively. The sensitivity, specificity and diagnostic accuracy of diffusion weighted imaging with ADC-T2WI fusion images in the diagnosis of lesions with a 1/2 depth of muscle were 82. 3% , 75% , and 85. 2%. Conclusions Routine pelvic MRI scan sequence has certain errors for the early diagnosis of endometrial cancer. On the contrary, the diffusion weighted imaging with ADC-T2 WI image fusion has remarkably increased diagnostic accuracy. The Tl WI of contrast-enhanced scan can clearly display most of the lesions by identifying the muscular infiltrations , and therefore can provide the most accurate information for the staging of early endometrial cancer.关键词
