Overview

Computed tomography can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive. It is not the technique of choice as it has limitations in defining shunt volume and pressure differences.

CT

Advantages

  • Provides additional anatomic details compared to echocardiography.
  • Helps in visualization of the aberrant pulmonary venous return (seen in sinus venosus defect). [1]
  • Done faster compared to MRI.
  • Avoids the need for general anesthesia in children.
  • Can identify associated heart anomalies.[1]

Disadvantages

  • Costly
  • Radiation can have long terms side-effect on growing children.
  • Not a modality for detecting or quantify a defect.[1]
  • Not a modality for quantifying shunt volume and pressure differences.[1]
