Embodiment Construction

[0040] figure 1 In vivo liver stiffness measurements in three imaging planes for the liver of a chronic liver patient are shown. In each plane, nine measurements are made.

[0041] Although hepatic fibrosis is considered a diffuse parenchymal disease, fibrosis actually varies in severity and location throughout the liver. Clinical findings indicate that the amount (stage) and location of fibrosis varies naturally. For example, if figure 1 Liver stiffness was measured in three imaging planes of the right liver lobe for liver patients by the PhilipsElastPQ feature, as shown. In each imaging plane, nine measurements were taken at nine different positions. Clearly, liver stiffness was on average higher in plane 1 than in planes 2 and 3, indicating a heterogeneous fibrosis distribution in viral hepatitis. Using the hardness cut-off values ​​derived from clinical studies, an average assessment of the fibrosis stage F0-F1 (none - mild fibrosis) for this patient can be achieved u...

Abstract

The present invention relates to an ultrasound elastography system (10) for providing a shear wave elastography measurement result of an anatomical site (32), wherein the ultrasound signal and image processing assembly (16) is further configured to determine a location (94, 95, 96) of a shear wave elastography measurement result within the three- dimensional image (98) of the anatomical site (32) and to display the location (94, 95, 96) of a shear wave elastography measurement result to the user. Further, a corresponding method is provided.

Description

technical field [0001] The present invention relates to an ultrasound elastography system for providing elastography measurements of an anatomical site, and an ultrasound elastography method for examining an anatomical site using the ultrasound elastography system. The invention also relates to a computer program for implementing such a method. Background technique [0002] Liver fibrosis and cirrhosis are a response to chronic liver injury from various causes, including viral, autoimmune, drug-induced, cholestatic and metabolic diseases. Cirrhosis can eventually lead to liver failure and is associated with increased relative mortality from primary liver cancer hepatocellular carcinoma. [0003] Staging and quantifying the extent of liver fibrosis is important in the management of patients with chronic liver disease. Liver biopsy is considered the "gold standard" for the diagnosis and staging of liver fibrosis. However, a liver biopsy can cause discomfort and anxiety for ...
