Although computed tomography (CT) has been shown to be accurate in delineating MAPCAs, its ability to differentiate between single- versus dual-supply MAPCAs is unclear. We investigated whether CT is non-inferior to angiography in discriminating single- versus dual-supply MAPCAs, while assessing procedural characteristics and outcomes.</p><p><strong>Methods: </strong>We retrospectively reviewed all patients with MAPCAs undergoing both CT and angiography (2016-2021). Images were independently reviewed by expert blinded readers. Diagnostic performance of CT in discriminating single- versus dual-supply MAPCAs was compared to angiography using non-inferiority paired testing.</p><p><strong>Results: </strong>Fifty-five MAPCAs in 17 patients were analyzed (median age at CT and angiography: 7 days [interquartile range, IQR, 1-745] and 74 days [IQR 49-751], respectively). Concordant classification (single/single and dual/dual) was observed in 53/55 vessels (96%); CT sensitivity and specificity was 97% (95% CI 84-100%) and 96% (95% CI 77-100%), respectively. CT versus angiography was non-inferior in discriminating single-versus dual-supply MAPCAs within 15%, 10%, and 5% margins (p < 0.001, p < 0.001, and p = 0.026). Inter-rater agreement between CT readers was excellent (91.3%, Kappa = 0.82).
