Endocardial blood volume in SA MRI images (left ventricle)

  1. Hello,

    I have a question about how to interpret the blood volume
    (with papillars) in short axis MRI images. I observe that
    always almost the endocardial heartwall is defined as a
    convex contour. It almost never get concave shape. Why it
    the endocard always indicated in this way? I see in some
    typical SA MRI images of the left ventricle that there is no
    contrast at cases where papillars are located. This seems
    resonable because there is no MRI signal originating from
    this location. However in most cases the endocardial heart
    wall is defined as a circular object, which isn't the cases
    conform the pixel (voxel) intensities. So why are the
    papillars then so large?

    Best Regards, Jean-Paul
