Table 1 Post-ablation atrial scar imaging techniques utilised in leading centres worldwide

	Centre	Subjects	Timing post-gadolinium	GBCA Dose	Scanner Strength	Slice thickness
Badger et al. (2010) [3]	Utah, USA	144	15 min (repeated if ‘suboptimal’)	0.1 mmol/kg (Multihance)	1.5 T	2.5 mm
Taclas et al. (2010) [11]	Boston, USA	19	15-20 min	0.2 mmol/kg (Magnevist)	1.5 T	4 mm
Hunter et al. (2013) [8]	Imperial/Barts, London, UK	50	20 min	0.4 mmol/kg (Magnevist)	1.5 T	4 mm
Bisbal et al. (2014) [7]	Barcelona, Spain	15	25-30 min	0.2 mmol/kg (Gadovist)	3 T	2.5 mm
Fukumoto et al. (2015) [4]	John Hopkins, USA	20	10-32 min	0.2 mmol/kg (Magnevist)	1.5 T	2 mm
Harrison et al. (2015) [9]	King’s College London, UK	20	20 min	0.2 mmol/kg (Gadovist)	1.5 T	4 mm
Akoum et al. (2015) [2]	DECAAF, Multicentre	177	15 min	0.1–0.2 mmol/kg (Multiple agents)	1.5 T (9 centres) 3 T (5 centres)	2.5 mm

In-plane resolution is 1.25 × 1.25 mm or 1.3 × 1.3 mm for all centres. GBCA: gadolinium based contrast agent. Note relaxivities vary significantly between GBCAs: Multihance r₁ = 6.3 L mmol^− 1 s^− 1 (1.5 T) r₁ = 5.5 L mmol^− 1 s^− 1 1 (3 T), Magnevist r₁ = 4.1 L mmol^− 1 s^− 1 (1.5 T) r₁ = 3.7 L mmol^− 1 s^− 1 1 (3 T), Gadovist r₁ = 5.2 L mmol^− 1 s^− 1 (1.5 T) r₁ = 5.0 L mmol^− 1 s^− 1 (3 T) [22]
