    Hi:

    The echocardiogram of a person with a PFO would show a distinct finding of a shunt, that is, a hole or passage way, thus allowing the movement of blood flow (in the upper or lower chambers) from the right side to the left side of the heart, or from the left side to the right side of the heart.

    How is PFO Diagnosed?

    An actual/true artifact is a false image (it's not what it appears to be). Just one example, as seen in a nuclear stress test, due to body habitus/anatomy or dense breast tissue.

    A tear is just that, also known as a rip, which may/can lead to a dissection.

    James Beckerman, MD, FACC responded:
    A patent foramen ovale, or PFO is a small hole in the membrane that exists between the two top chambers of the heart. About 15-20% of people have one.

    An artifact is essentially an "error" in a test (typically an imaging test like an xray) that may mislead someone into thinking that there is a true abnormality when one is not actually present.

    A CT scan is practically much simpler to perform than an MRI. Some things are imaged better on CT, some on MRI.
