Patient and device related factors affecting artifact size and cardiac visualization when performing cardiac MRI in patients with implanted defibrillators

Wideband magnetic resonance sequencing to decrease image artifact in a child with a cardiac implantable device

“… 10 , 11 The ideal way to reduce imaging artifact is to acquire images as far away from the CIED as possible, but this strategy is limited when obtaining cardiac imaging in small, pediatric patients. 11 , 12 A recently published pediatric study found that 6 of 9 patients with uninterpretable MRI were <18 years of age. 4 As patient factors (eg, body shape and size, anatomy) and device factors (eg, model, size, shape, position in the body) cannot be changed, we propose that wideband sequencing is an alternative strategy to reduce potential image artifact.…”

MRI in pediatric and congenital heart disease patients with CIEDs and epicardial or abandoned leads

“…Most MRIs (64%) in our study had no artifact present, and 83% of MRIs were clinically useful. Previous studies have identified multiple risk factors for developing CIED artifact in MRIs including CIED type, CIED manufacturer, patient body mass index, location of the CIED in relation to the field of view, and type of imaging sequence performed 24‐26 . Some studies have found that pacemakers create little to no artifact and rarely affect the clinical utility of the scan, but ICDs may cause artifact in up to 44% of MRIs 24,27 .…”
