MRI with intrathecal MRI gadolinium contrast medium administration: a possible method to assess glymphatic function in human brain

Open access

Abstract

Recently, the “glymphatic system” of the brain has been discovered in rodents, which is a paravascular, transparenchymal route for clearance of excess brain metabolites and distribution of compounds in the cerebrospinal fluid. It has already been demonstrated that intrathecally administered gadolinium (Gd) contrast medium distributes along this route in rats, but so far not in humans. A 27-year-old woman underwent magnetic resonance imaging (MRI) with intrathecal administration of gadobutrol, which distributed throughout her entire brain after 1 and 4.5 h. MRI with intrathecal Gd may become a tool to study glymphatic function in the human brain.

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?

  • Literature reporting human in vivo CSF tracer studies is lacking, and observations made in animals have not been translated into humans.

    “However, literature reporting human in vivo CSF tracer studies is lacking, and observations made in animals have not been translated into humans.”

    From Brain-wide glymphatic enhancement and clearance in humans assessed with MRI. (2018) · cites this paper as [12]

    The Introduction (page not provided) says that how rodent tracer observations relate to human brain physiology had not been established, supporting the claim's historical point. But it also describes existing human intrathecal contrast MRI for CSF leaks, and this paper reports a human tracer observation. It therefore does not support an unqualified claim that human in vivo CSF tracer studies are lacking or that the animal observations remain untranslated. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Two recent human studies demonstrated brain parenchyma enhancement subsequent to intrathecal administration of a MRI contrast agent, but observations were limited to selected ROIs.

    “Two recent human studies demonstrated brain parenchyma enhancement subsequent to subarachnoid (intrathecal) administration of a MRI contrast agent, but observations were limited to selected ROIs (12, 13).”

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.
