An update on neuroimaging of multiple sclerosis

Matthews, Paul M·2004·Current Opinion in Neurology

Abstract

PURPOSE OF REVIEW: The advent of magnetic resonance imaging provided a powerful tool for monitoring the dynamics of pathological changes in multiple sclerosis, but conventional approaches offer only limited information that is directly relevant to clinical progression. Continued developments of imaging methods and their use for diagnosis, monitoring pathology and understanding disease progression are reviewed here. RECENT FINDINGS: Magnetic resonance imaging is now well established as a clinical test for multiple sclerosis, but the specific ways in which imaging information should best be incorporated into diagnostic criteria are still debated. New data defining the substantial pathology in grey matter, regional variation in the progression of pathology and the relationship between the spatial distribution of pathological changes and symptoms are providing an increasingly compelling description of changes relevant to disability. Molecular-imaging approaches promise much more detailed descriptions. Functional magnetic resonance imaging, which suggests that adaptive functional changes could limit clinical expression of pathology, are providing further clues to the link between measures of pathology and disability. SUMMARY: New data further reinforce the view that pathology relevant to clinical progression of multiple sclerosis can be defined by imaging. A range of biologically more specific markers are becoming available using positron emission tomography, as well as magnetic resonance imaging.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Increases in phasic activity of midbrain dopaminergic neurons result in increased dopamine release at target sites, as inferred to occur in schizophrenia.

    “An implication here, for which there is some evidence, 66 is that increases in the phasic activity of midbrain dopaminergic neurons will result in increased dopamine release at target sites, such as has been inferred to occur in patients with schizophrenia.67,68”
  • In mice, disrupting normal oligodendrocyte development by blocking Neuroregulin-1 signaling resulted in significantly increased levels of dopamine receptors and transporters in the nucleus accumbens and striatum, similar to those in patients with schizophrenia.

    “the affected mice also showed significantly increased levels of dopamine receptors and transporters in the nucleus accumbens and striatum, similar to those exhibited by patients with schizophrenia.68”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
