I am trying to show that the position of the heart relative to the liver was significantly different in the patient's 2/27 scan -- thus accounting for the more severe overcorrection in that study.
I have attempted to align the livers in the attenuation scans from the 2/27
and the 4/23 studies here.
The red overlays are from the respective stress emission scans.
Notice how much more inferior (toward the patient's feet) the heart is in
the 2/27 stress scan. (Either the liver was more superior on 2/27 or the
heart was more inferior, I can't tell) This means that the 2/27 scan had a
more severe effect from the shadow of the liver, thus explaining the larger
effect on the stress bullseyes from the 2/27 scan.
