Overview
There are no MRI findings associated with patent foramen ovale.
MRI
- Contrast-enhanced MRI is not commonly used but may be helpful in the diagnosis of patent foramen ovale. The presence of an early contrast enhancement due to intracardiac right-to-left shunting in the left atrium before the contrast agent reaches the pulmonary veins is diagnostic of patent foramen ovale.[1]
- The grading of PFO using contast-enhanced MRI include:[1]
- Grade 0: No contrast enhancement in the left atrium before the contrast agent reached the pulmonary veins.
- Grade 1: Only slight contrast enhancement close to the atrial septum without enhancement of the entire left atrium before the contrast agent reached the pulmonary veins.
- Grade 2: Only slight contrast enhancement in the left atrium before the contrast agent reached the pulmonary veins; and grade 3, bright contrast enhancement in the left atrium before the contrast agent reached the pulmonary veins.
