Advanced MRI technique detects cellular brain changes in living Huntington's disease patients

Researchers used specialized imaging to estimate cell density changes, though tracking long-term disease progression requires further study.

The short version

  • Researchers utilized an advanced imaging technique called Sandi to estimate cellular abnormalities in the basal ganglia of living Huntington's patients.[Scientific American]
  • The study compared strong-gradient MRI scans from 56 individuals with Huntington's disease to 57 healthy volunteers.[Scientific American]
  • Huntington's patients exhibited lower cell-body density, larger cell-body size, and increased space between cells in specific brain regions.[Scientific American]
  • Further research is required to adapt the technique for standard hospital MRI scanners and to determine if it can track disease progression or treatment responses.[Scientific American]

Key facts

  • Huntington's disease affects roughly 8,000 people in the U.K., generally onsetting between 30 and 50 years of age, and currently lacks a cure.[Scientific American]
  • Researchers analyzed diffusion MRI data using soma and neurite density imaging (Sandi) to indirectly estimate cell body dimensions and density.[Scientific American]
  • The study evaluated 56 individuals diagnosed with Huntington's disease alongside 57 age- and sex-matched healthy control participants.[Scientific American]
  • Scans revealed lower cell-body density estimates, larger cell-body size estimates, and greater intercellular spacing in the basal ganglia of Huntington's patients, but not in the thalamus.[Scientific American]
  • Estimates of cell-body size and density, along with age, explained up to 63% of observed tissue shrinkage in parts of the striatum.[Scientific American]

What remains uncertain

  • Because the study captured only a single snapshot in time, it remains unverified whether the Sandi technique can track disease progression or reliably detect treatment effects.[Scientific American]
  • The imaging method was conducted using strong-gradient MRI equipment and has not yet been adapted or validated for standard hospital MRI scanners.[Scientific American]
