Overview
Additional imaging with diffusion weighted MRI and radionuclides also aid in the diagnosis of galactosemia.
Other imaging modalities
Diffusion-weighted imaging[1]
Hypointense lesions within the white matter with higher apparent diffusion coefficient values
MR Spectroscopy[1]
Gal-ol signal intensity within the parieto-occipital white matter
Per-rectal portal scintigraphy[2]
Serial scintigrams after per-rectal instillation of technetium 99m-pertechnate may show evidence of portosystemic shunts in galactosemic individuals without enzyme deficiency. The blood galactose levels can also be measured by this method in a non-invasive manner with minimal exposure to the radionuclide.
