[Evaluation of gastroesophageal varices with three-dimensional visualization technology]

Area of Science:

• Radiology
• Medical Imaging
• Gastroenterology

Background:

• Gastroesophageal varices (EGV) are a serious complication of portal hypertension.
• Accurate evaluation of EGV distribution and blood supply is crucial for effective management.
• Traditional imaging methods may have limitations in visualizing complex vascular structures.

Purpose of the Study:

• To evaluate the prognostic value of the Medical Image Three-dimensional (3D) Visualization System (MI-3DVS) in assessing EGV.
• To compare the efficacy of MI-3DVS with CT-maximum intensity projection (CT-MIP) in demonstrating EGV characteristics and blood supply.

Main Methods:

• Multi-slice computed tomography (MSCT) data from 51 EGV patients were analyzed.
• 3D reconstruction was performed using MI-3DVS and CT-MIP.
• Demonstration rates of collateral vessels, EGV typing, and blood supply were compared between the two methods.

Main Results:

• MI-3DVS showed high agreement with CT-MIP in demonstrating various types of varices and shunts (κ = 0.882-1.000).
• Both methods demonstrated high agreement in EGV classification (weighted Kappa = 0.848).
• Blood supply distribution significantly correlated with EGV classification (P < 0.01).

Conclusions:

• MI-3DVS effectively visualizes EGV location, diameter, and blood supply, aiding in understanding collateral circulation.
• The 3D reconstruction capability of MI-3DVS offers significant guidance for optimizing therapeutic schedules and preoperative planning.
