Tetralogy of fallot MRI
Introduction
Overview
Overview
Magnetic resonance imaging can be helpful as a diagnostic tool in patients in whom the echocardiographic findings are inconclusive.
MRI
MRI
Advantages
- It can be used in cases where echocardiographic results are inconclusive.
- Assists in the measurement of heart volumes, blood flow and ventricular wall thickness.
- Magnetic resonance angiography can better visualize the heart vasculature.
- Phase velocity mapping helps in measuring the ratio of pulmonary to systemic blood flow (Qp:Qs).
Disadvantages
- For successful MRI procedure breath holding is required, which is sometimes difficult to achieve with small children. Due to this, the procedure may be performed under general anesthesia in children.

Diagnostic Recommendations for Tetralogy of Fallot
| Class I |
| 1.CMR is useful to quantify ventricular size and function, pulmonary valve function, pulmonary artery anatomy, and left heart abnormalities in patients with repaired TOF. (Level of Evidence: B-NR) |
| 2.Coronary artery compression testing is indicated before right ventricle–to-PA conduit stenting or transcatheter valve placement in repaired TOF. (Level of Evidence: B-NR) |
