Wang XM, et al. - The value of 3-D contrast-enhanced ultrasonography (3-D-CEUS) in the diagnosis of celiac artery compression syndrome (CACS) is estimated in this study. The outcome suggests that the 3-D-CEUS can accurately uncover the characteristic hooked appearance and dynamic nature of CACS with respiration, and thus, it represents a new, non-invasive approach to CACS diagnosis.

• In this study, they evaluated patients suspected of having CACS with 3-D-CEUS and contrasted with computed tomography angiography.
• Diagnostic accuracy was assessed with a receiver operating characteristic curve.
• Three-dimensional CEUS uncovered 19 positive and 9 negative cases.
• The contrast agent did not change with respiration in the negative group.
• The contrast agent displayed a hook-shaped stenosis on expiration and returned to normal on inspiration in the positive group.
• Computed tomography angiography showed 1 false-positive case and 1 false-negative case.
• The sensitivity and specificity of 3-D-CEUS were 95% and 89%, respectively.
• The area under the receiver operating characteristic curve was 0.982 (p<0.01).
