Magnetic resonance imaging in congenital heart disease (CHD)

Posted on July 16, 2009 by admin Comments Off

Advantages of MRI in congenital heart disease imaging 

  1. No ionizing radiation
  2. 3D anatomy can be visualised
  3. Blood flow analysis is possible - black blood and white blood imaging > flowing blood is seen as white in white blood imaging.

Indications for cardiac magnetic resonance (CMR) imaging in CHD

  1. Repaired tetralogy of Fallot – Right ventricular outflow tract aneurysm  has to be looked fo in cases in which a trans annular patch has been used.
  2. Evaulation of Aorti acrch pathology like coarctation and double aortic arch
  3. Transposition of great arteries
  4. Evaluation of vascular rings
  5. Evaluation of regional funciton by CMR
  6. Imaging of pulmonary veins
  7. Evaluation of endo grafts
  8. Coronary imaging by MR  – Anomalous origin right coronary artery from RCA from left sinus can cause sudden cardiac death (SCD) during exercise, because the artery courses between the aorta and the pulmonary trunk.

Special modalities in CMR

  1. Phase contrast MR
  2. MR tagging for asssessment of regional function by MR
  3. CMR overlay over live fluro has been evaluated experimentally
