Overview
Magnetic resonance imaging can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.

ACC/AHA 2008 Guidelines - Recommendation for Imaging - Tricuspid atresia (DO NOT EDIT)[1]

Magnetic resonance imaging (MRI) can be used as a diagnostic modality in congenital heart diseases.
Advantages of using MRI are:
- It can be used in cases where echocardiographic results are inconclusive.
- Helps in measuring heart volumes, blood flow and ventricular wall thickness.
- The magnetic resonance angiography helps in better visualization of heart vasculature
- Phase velocity mapping helps in measuring the ratio of pulmonary to systemic blood flow (Qp:Qs).
Disadvantage:
For successful MRI procedure breath holding is required, which is sometimes difficult to achieve with small kids. Due to this, the procedure is done under general anesthesia in children.
