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).
• Done faster compared to MRI.
• Avoids the need for general anesthesia in children.
• Can identify associated heart anomalies.

Disadvantages

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