| Ultrasound (US) elastography is a tool that indicates the hardness of a lesion.
Recent studies using elastography with freehand compression have shown similar
diagnostic performance to conventional US in differentiating benign lesions from
malignant breast masses. On the other hand, the acquired information is not quantitative,
and the reliability of the imaging technique to correctly compress the tissue
depends on the skill of the operator, resulting in substantial interobserver variability
during data acquisition and interpretation. To overcome this, shear wave elastography
was developed to provide quantitative information on the tissue elasticity. The system
works by remotely inducing mechanical vibrations through the acoustic radiation force
created by a focused US beam. This review discusses the principles and examination
techniques of the two types of elastography systems and provides practical points to
reduce the interobserver variability or errors during data acquisition and interpretation. |
