We found that standard measurements showed strong correlation between CTA and MRA (r = 0.92- 0.99) and perfect agreement between two observers (ICC = 0.97 - 0.99). We also demonstrated four MRA features which are feasible for the detection of endoleaks. The “mottled high intensity” and “creeping high intensity with low band rim” were significant positive findings (P < 0.001), and “no signal black spot” and “layered high intensity area” were also significant negative findings (P < 0.031). The observation of these findings showed feasible diagnostic performance for detecting endoleaks which also showed reliable reproducibility among blinded observers.
