Abstract:
During the past few years, there have been a number of new technical developments in the field of high-performance ultrasound diagnostics, which should help us to better assess dynamic vascular changes with ultrasound. BMUS enables us to get important anatomical variants with regard to the portal venous vessels and the hepatic veins. With color-coded duplex sonography (CCDS), and power Doppler (PD), examiners can carry out a comprehensive hemodynamic assessment of the portal venous. However, low flow settings in the vein have always been a particular challenge for CCDS, since the examiner requires special experience and artefacts often occur. In this review article, we reviewed the technical basics and diagnostic possibilities of new digital vascular ultrasound methods, 3D flow methods and contrast enhanced ultrasound (CEUS) in the assessment of portal venous flow changes.

Ultrasound I: Abdominal Ultrasonography
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...
