Sonoelastography in the diagnosis of endometrial cancer

Objective. To evaluate the efficiency of compression sonoelastrography in the diagnosis and staging of endometrial cancer. Subject and methods. Forty-two patients with the verified diagnosis of endometrial cancer were examined. Preoperatively, all the patients underwent ultrasound study using an ultrasound compression sonoelastography procedure on a Hitachi Hi Vision Preirus with an endocavity transducer, 8-4 MHz frequency. The improved and adapted classification of elastographic types (types 1-3, benign; types 4-5, malignant) in gynecology was used to determine the degree of tissue density. The results of ultrasound study with elastography were compared with histological data. Results. The sensitivity and specif icity of sonography in the diagnosis of endometrial cancer were 87.8% and 86/9%, respectively. Conclusion. Inclusion of static elastography in comprehensive ultrasound study considerably enhances its informative value in the diagnosis of endometrial cancer.
