Overview
Magnetic resonance imaging can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.
MRI
Magnetic resonance imaging (MRI) can be used as a diagnostic modality in congenital heart diseases.
Advantages
- 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).
Disadvantages
- 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.
- In patients with patent ductus arteriosus, the usage of MRI can demonstrate the abnormality and its severity. The magnitude of the shunt can also be determined by radionuclide flow studies.
