Abstract
Conventional Ultrasonography imaging does not provide information on mechanical properties of body tissues. Advances in ultrasound like contrast enhanced ultrasound, multiplaner 3D ultrasound and elastography have improved the performance of ultrasound in detection and characterization of pathologies and also has added a new dimension to conventional imaging technique. At this time, the use of elastography is not recommended for characterization of focal liver lesions, however in diffuse liver diseases Ultrasound elastography finds a role in identifying, classifying and grading fibrosis. Liver biopsy has been regarded as the gold standard to detect and classify liver fibrosis. However, due to high cost, inherent complications, invasive nature and its observer and sampling inadequacy, alternative methods to biopsy like Ultrasound elastography might have a role to play in detecting and grading liver fibrosis. This review focuses on the type of elastography and its role and applicability in various liver pathologies.
