Abstract

Background Brain injury is observed on cranial magnetic resonance imaging preoperatively in up to 50% of newborns with congenital heart disease. Newer imaging techniques such as diffusion tensor imaging provide sensitive measures of the white matter integrity. The objective of this study was to evaluate the diffusion tensor imaging analysis technique of tract-based spatial statistics in newborns with congenital heart disease.Methods Term newborns with congenital heart disease who would require surgery at less than 1 month of age were prospectively enrolled (n = 19). Infants underwent preoperative and postoperative brain magnetic resonance imaging with diffusion tensor imaging. Tract-based spatial statistics, an objective whole-brain diffusion tensor imaging analysis technique, was used to determine differences in white matter fractional anisotropy between infant groups. Term control infants were also compared with congenital heart disease infants. Postmenstrual age was equivalent between congenital heart disease infant groups and between congenital heart disease and control infants.Results Ten infants had preoperative brain injury, either infarct or white matter injury, by conventional brain magnetic resonance imaging. The technique of tract-based spatial statistics showed significantly lower fractional anisotropy (P < 0.05, corrected) in multiple major white matter tracts in the infants with preoperative brain injury compared with infants without preoperative brain injury. Fractional anisotropy values increased in the white matter tracts from the preoperative to the postoperative brain magnetic resonance imaging correlating with brain maturation. Control infants had higher fractional anisotropy in multiple white matter tracts compared with infants with congenital heart disease.Conclusion Tract-based spatial statistics is a valuable diffusion tensor imaging analysis technique that may have better sensitivity in detecting white matter injury compared with conventional brain magnetic resonance imaging in term newborns with congenital heart disease.

  • This finding of lower fractional anisotropy in congenital heart disease has been replicated by several other studies over the last decade.

    “This finding has been replicated over the last decade by several other studies.[53][54][55]”
  • Postnatal white matter fractional anisotropy is lower in infants with congenital heart disease who develop preoperative brain injury, supporting coexistence of white matter dysmaturation and acquired brain injury in early life.

    “Postnatal white matter fractional anisotropy is lower in infants with CHD who develop preoperative brain injury, 53 supporting the coexistence of white matter dysmaturation and acquired brain injury in early life.”
  • Preoperative brain injury is accompanied by decreased microstructural white matter maturation, and fetal brain abnormalities are associated with increased risk of acquired brain injury after birth.

    “Preoperative brain injury is accompanied by decreased microstructural white matter maturation in several studies, 53,55,74 while fetal brain abnormalities are associated with an increased risk of acquired brain injury after birth.85”

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.
