Elastography is an advanced imaging technique that measures the stiffness or elasticity of tissues within the body. This non-invasive method is particularly useful in assessing conditions where tissue stiffness is a key indicator, such as liver fibrosis, breast tumors, and thyroid nodules.

In elastography, sound waves are used to generate images that display the mechanical properties of tissues. These images help differentiate between healthy and diseased tissue, as abnormal tissues often have different stiffness characteristics compared to normal tissues. For example, in the liver, elastography can detect fibrosis—a common complication of chronic liver diseases—by measuring how stiff the liver tissue has become. Similarly, in breast imaging, elastography can help distinguish between benign and malignant tumors, as cancerous tissues typically exhibit higher stiffness.

Elastography is often integrated with traditional ultrasound, providing a more comprehensive evaluation without the need for invasive procedures like biopsies. The results are immediate, allowing for quicker decision-making and treatment planning. This technique enhances diagnostic accuracy and is a valuable tool in monitoring the progression of diseases and the effectiveness of treatments, offering both patients and healthcare providers a more detailed and reliable assessment of tissue health.
