Accuracy and Reproducibility of Sonoelastography for the Assessment of Fibroids and Adenomyosis, with Magnetic Resonance Imaging as Reference Standard.

The aims of this prospective diagnostic evaluation study were (i) to estimate the inter-observer agreement and reproducibility of real-time sonoelastography and real-time gray-scale ultrasound in the measurement of uterine and fibroid volumes; (ii) to evaluate the agreement between real-time gray-scale ultrasound, sonoelastography and magnetic resonance imaging with respect to these outcomes; and (iii) to evaluate the diagnostic accuracy of sonoelastography in the diagnosis of uterine pathology on stored sonoelastography and gray-scale cine loops. Women without a history of uterine pathology and with the diagnosis intrauterine fibroids or adenomyosis were included. All participants underwent gray-scale ultrasound, sonoelastography and magnetic resonance imaging. Compression sonoelastography was found to have high inter-observer and inter-method agreement for the measurement of uterine and fibroid volumes. The addition of sonoelastography to gray-scale ultrasound seems to be useful in the differentiation between fibroids, adenomyosis and normal uteri as reflected by an increase in accuracy and diagnostic agreement.
