Abstract/OtherAbstract:
BACKGROUND: With the improvement of MR technology, three-dimensional dynamic contrast-enhanced MR angiography (3D-DCE-MRA) may be the optimal vascular imaging method for preoperative evaluation of liver transplantation candidates. This study was undertaken to determine the value of 3D-DCE-MRA in the assessment of recipient vessels in orthotopic liver transplantation (OLT). METHODS: The surgical and pathological records were taken as the "gold standards". Eighteen cases of OLT were retrospectively analyzed to assess the image quality of MRA, including the signal-to-noise ratio (SNR) in arteries and veins, depiction of vascular variation and vessel disease, and the accuracy of vascular diameter measurement. RESULTS: 3D-DCE-MRA of 34 cases was carried out before OLT. The rates (excellent and good) showing hepatic arteries and portal vein for 3D-DCE-MRA were 94.1% (32/34) and 88.2% (30/34), respectively. The SNRs of the celiac axis and portal vein measurements from 3D-DCE-MRA were 20.58+/-3.74 and 13.43+/-4.12, and the mean diameters were 3.4+/-0.3 mm and 13.1+/-3.2 mm, respectively. There were 5 cases of vessel variation according to the Michel's classification. Of the 34 patients, 18 were compared radiologically and pathologically. The accuracy of depiction of the hepatic artery and portal vein with 3D-DCE-MRA was 100% for both; 3D-DCE-MRA precisely assessed 4 cases of more than moderate stenosis in hepatic arteries, 2 cases of small-caliber hepatic artery, 3 cases of venous stenosis at the second porta hepatis, 6 cases of collateral vasculature, 1 case of portal vein thrombosis and 1 case of portal vein aneurysm; all were confirmed pathologically. CONCLUSION: 3D-DCE-MRA may be the first choice for recipient vascular assessment before OLT.
