[3D real time contrast enhanced ultrasonography,a new technique]

Area of Science:

• Medical imaging
• Diagnostic ultrasound
• Hepatobiliary and pancreatic imaging

Background:

• Three-dimensional (3D) sonography is established in gynecology but less utilized in abdominal imaging.
• Advances in computer technology enable sensor-free 3D data acquisition using motion detection and image registration.
• Contrast-enhanced ultrasound (CEUS) improves lesion detection and characterization.

Purpose of the Study:

• To evaluate the feasibility and potential of real-time 3D ultrasound for liver and spleen imaging.
• To assess the utility of 3D ultrasound with contrast enhancement for characterizing hepatic and splenic tumors.
• To explore the role of 3D ultrasound in surgical planning through precise tumor localization.

Main Methods:

• Real-time 3D ultrasound imaging was performed on 10 patients.
• Contrast-enhanced phase inversion imaging with a low mechanical index was utilized.
• 3D data were acquired without position sensors before and after contrast administration.

Main Results:

• The study reports the first use of real-time 3D ultrasound for liver and spleen imaging in patients.
• The technique allowed for topographic localization of masses relative to hepatic veins and portal vein branches.
• Potential for improved detection and characterization of liver and splenic tumors was observed.

Conclusions:

• Real-time 3D ultrasound, particularly with contrast enhancement, is a promising tool for abdominal applications.
• This technology may enhance the detection and characterization of liver and splenic tumors.
• 3D ultrasound facilitates precise anatomical localization crucial for surgical planning.
