Abstract

Objective: To investigate the clinical value of 3D CEMRA of hepatic vessels． Methods: 3D CEMRA was performed in 82 cases． When contrast reached descending aorta, 3D scan started. Arterial phase, portal venous phase, vena cava phase were acquired. The images were subtracted and reconstructed by MIP or MPR. The quality of image was evaluated． Results: With this technique high quality of images were obtained. Contrast volume and flow rate correlated with the time when bolus reached the target vessel. Contrast volume and flow rate have linear correlation with the signal of hepatic vessel. Conclusion: 3D CEMRA technique can grasp the exact time when contrast reached target vessel. Combined with optimal contrast volume and injection rate can improve the image quality obviously．
