Cardiac MR imaging (CMRI) also does not expose the patient to ionizing radiation and is therefore ideal for serial post - surgical follow-up. The exact implementation of MRI in patient management and therapeutic consequences of the provided parameters need to be evaluated in large follow - up studies. Goals of MRI in TOF patients are: Quantification of the amount of pulmonary regurgitated volume allows for a more accurate selection of patients who may benefit from surgical treatment. Imaging the anatomy of the right ventricular outflow tract (e.g., ventricular septal defect and RVOT patches). Quantification of tricuspid regurgitation, and pulmonary - to - systemic flow ratio. It is recommend that all patients with TOF undergo anatomic and functional evaluation using MRI at least once
