Abstract: Objective To investigate the imaging techniques of enhanced T1 high resolution isotropic volume examination (e-THRIVE) multi-phase dynamic contrast-enhanced scanning technology.Methods 83 patients with liver diseases underwent routine and contrast-enhanced MR scanning.e-THRIVE axial volume scan was used in contrast enhanced MRI.The raw data acquired were post-processed with maximum intensity projection(MIP) technique,and to observe the esophageal and gastric varicose vein's display in different injection rates of contrast agent with delayed scan time.Results The varciation of esophageal and gastric blood vessels in 79 cases were detected,the MIP images showed the overall effect of varicose blood vessels,and the axial images displayed that varicose blood vessels' location,in the submucosal or the inside or outside of the lumens.The ratio of high-quality image reached 72％.Conclusion The high-quality vascular imaging technology of e-THRIVE depends on appropriate injection rate and the right amount of contrast agent,the best delayed scanning time and patients with good breath-hold.
