MRI

Magnetic resonance imaging (MRI) can be used as a diagnostic modality in congenital heart diseases.[1]

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.
