MRI
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 an MRI procedure to be successful the patient is required to hold their breath, which is sometimes difficult to achieve with small kids. Due to this, the procedure is done under general anesthesia in children.
