Abstract:
Objective To evaluate the usefulness of three dimensional dynamic contrast enhanced magnetic resonance angiography(3D DCE MRA) in the diagnosis of vena caval abnormalities. Methods 3D DCE MRA was performed on fifty two patients with suspected vena caval anomaly, thrombosis, stenosis, occlusion, or compression. Image quality and the presence of venous abnormalities and collaterals were evaluated. Comparison with conventional venacavography( n =15) and surgical findings( n =18) was made. Results 3D DCE MRA images were of diagnostic quality without artifact for all 52 patients. 3D DCE MRA clearly showed vascular anatomy, anomaly and various disorders. The site, extent, cause of venous obstruction, and collateral pathways were well depicted. According to venography or surgery, the sensitivity and specificity of 3D DCE MRA in the diagnosis of abnormalities of vena cava were both 100%. In addition, it had advantages regarding demonstration of extravascular lesions and multiplanar capabilities. Conclusion 3D DCE MRA is simple to perform and accurate in detecting various vena caval abnormalities.
