Summary
This review highlights how ultrasound (sonography) reveals normal liver tissue and identifies diffuse liver diseases. It covers key conditions like hepatitis, fatty liver, fibrosis, and cirrhosis for better diagnosis.
Area of Science:
- Medical Imaging
- Hepatology
- Diagnostic Ultrasound
Background:
- Diffuse liver diseases significantly impact patient health and require accurate diagnostic methods.
- Sonography is a widely accessible and non-invasive imaging modality for evaluating liver parenchyma.
Purpose of the Study:
- To review the sonographic features of normal hepatic parenchyma.
- To describe the characteristic ultrasound findings of common diffuse liver pathologies.
Main Methods:
- Review of existing literature and established sonographic criteria for diffuse liver disease.
- Correlation of sonographic findings with histopathological data where applicable.
Main Results:
- Detailed description of normal liver echotexture, echogenicity, and vascularity.
- Specific sonographic patterns for hepatitis, fatty liver (steatosis), hepatic fibrosis, cirrhosis, and diffuse metastases are presented.
- Ultrasound can detect changes indicative of opportunistic infections affecting the liver.
Conclusions:
- Sonography is a crucial tool for the initial assessment and characterization of diffuse liver diseases.
- Understanding normal and abnormal sonographic appearances aids in differential diagnosis and patient management.
