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