Fig. 4.

The prevalence and distribution of artefact-free segments as percentage with arm-down and arm-raised scanning position in patients with left-sided PM (on the left) and ICD (on the right). In patients with PM, the IQ of the bSSFP cine and LGE SAX sequences are illustrated; in patients with ICD, the SPGR cine in SAX and 2 ch planes are illustrated respectively. CIED-induced artefact distribution shows that the anterior wall and septal segments are most affected by the artefacts. bSSFP = balanced steady-state free precession; CIED = cardiac implantable electronic device; CMR = cardiac magnetic resonance imaging; ICD = implantable cardioverter-defibrillator; LGE = late-gadolinium enhancement; PM = pacemaker; SAX = short axis; SPGR = spoiled gradient echo; 2ch = two-chamber
