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]
