^a, Kappa test for the consistency between each of the three MRA sequences and the MDCT; ^b, morphological relationship between the tumors and vessels; ^c, a total of 390 vessels from 30 patients were assessed in regard to the morphological relationship between tumors and vessels. FB, free-breathing; BH, breath-holding; RT, respiratory-triggered; MRA, magnetic resonance angiography.
