Recent advances in sonography, including elastography, contrast-enhanced ultrasound, and image fusion, enhance abdominal imaging. These techniques improve the diagnosis of liver disease, tumors, and trauma, establishing sonography as a more autonomous diagnostic tool.
Area of Science:
- Medical Imaging
- Diagnostic Sonography
- Interdisciplinary Medicine
Background:
- Sonography is a primary diagnostic tool for abdominal investigations.
- This article reviews recent groundbreaking advances in sonographic imaging.
Purpose of the Study:
- To provide an interdisciplinary overview of novel sonographic software techniques.
- To highlight advancements extending the scope of sonographic examinations.
Main Methods:
- A selective literature survey of PubMed publications from 2004-2022 was conducted (2021-2022).
Main Results:
- Novel techniques include elastography for liver disease assessment (e.g., fibrosis, cirrhosis), contrast-enhanced sonography for tumors and trauma, and image fusion with other modalities.
- Elastography shows high accuracy for diagnosing liver fibrosis and cirrhosis.
- Contrast-enhanced sonography demonstrates high sensitivity for malignant lesions.
Conclusions:
- Continuous improvements in B-scan technology, high-frequency probes, and new techniques are establishing sonography as an autonomous examination procedure.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
