A 36 g mouse was injected with inorganic I-125 at the
laboratory of Harvard Prof. Amin I. Kassis. It was
euthanized a few minutes after injection and
transported to NeuroPhysics in Shirley,
Massachusetts.
Over the next two days a number of scans were
performed with the company’s
MollyQ™ 50
high resolution SPECT scanner.
On this page we see a surface-rendered truncated
section of the mouse extending from behind the nose
to the thorax. Right and left side views of the
section are shown in the top images. The section is
gradually rotated coming to the straight-on image at
the bottom.
The concentration of I-125 is depicted in a gray
scale that transits to blue in the regions of highest
activity.
Tissue assay gave a total of 2410 µCi (67 µCi/g).
Since the specific activity of muscle samples was 98
µCi/g, over half of the total was taken up by
muscle.
