  • 2021‎

BACKGROUND The pathophysiology of traumatic subarachnoid hemorrhage and brain injury has not been fully elucidated. In this study, we examined abnormalities of white matter in isolated traumatic subarachnoid hemorrhage patients by applying tract-based spatial statistics. MATERIAL AND METHODS For this study, 10 isolated traumatic subarachnoid hemorrhage patients and 10 age- and sex-matched healthy control subjects were recruited. Fractional anisotropy data voxel-wise statistical analyses were conducted through the tract-based spatial statistics as implemented in the FMRIB Software Library. Depending on the intersection between the fractional anisotropy skeleton and the probabilistic white matter atlases of Johns Hopkins University, we calculated mean fractional anisotropy values within the entire tract skeleton and 48 regions of interest. RESULTS The fractional anisotropy values for 19 of 48 regions of interest showed significant divergences (P<0.05) between the patient group and control group. The regions showing significant differences included the corpus callosum and its adjacent neural structures, the brainstem and its adjacent neural structures, and the subcortical white matter that passes the long neural tract. CONCLUSIONS The results demonstrated abnormalities of white matter in traumatic subarachnoid hemorrhage patients, and the abnormality locations are compatible with areas that are vulnerable to diffuse axonal injury. Based on these results, traumatic subarachnoid hemorrhage patients also exhibit diffuse axonal injuries; thus, traumatic subarachnoid hemorrhage could be an indicator of the presence of severe brain injuries associated with acute or excessive mechanical forces.


Differences in corpus callosum injury between cerebral concussion and diffuse axonal injury.

  • Medicine‎
  • 2019‎

We investigated differences in corpus callosum (CC) injuries between patients with concussion and those with diffuse axonal injury (DAI) by using diffusion tensor tractography (DTT).

  • Sung Ho Jang‎ et al.
  • Medicine‎
  • 2020‎

We report a stroke patient who showed increased thalamocortical connectivity to the medial prefrontal cortex (mPFC) with recovery of impaired consciousness that was demonstrated on diffusion tensor tractography (DTT) of the ascending reticular activating system (ARAS).


Changes in the prefronto-thalamic tract following cranioplasty: Case reports.

  • Eun Bi Choi‎ et al.
  • Medicine‎
  • 2021‎

The prefrontothalamic tract (PTT) injury is associated with various neuropsychological impairments including cognitive impairment. We report on three women with hemorrhagic stroke who showed changes in the PTT following cranioplasty (C/P) using diffusion tensor tractography (DTT) images.


Extensive traumatic axonal injury of brain due to violence: A case report.

  • Sung Ho Jang‎ et al.
  • Medicine‎
  • 2018‎

Many studies using diffusion tensor imaging (DTI) have demonstrated traumatic axonal injury (TAI) in patients whose conventional brain magnetic resonance imaging (MRI) results are negative following head trauma. Injury mechanism for TAI in these patients has been mainly associated with motor vehicle accident, whereas very little is known about TAI by violence.


Restoration of the ascending reticular activating system compressed by hematoma in a stroke patient.

  • Sung Ho Jang‎ et al.
  • Medicine‎
  • 2017‎

We report on restoration of the ascending reticular activating system (ARAS), compressed by an intracerebral hematoma and perihematomal edema following a stroke. The restoration of the ARAS was demonstrated by diffusion tensor tractography (DTT).

  • Sung Ho Jang‎ et al.
  • BMC neurology‎
  • 2020‎

We investigated the relationship between consciousness and the ascending reticular activating system (ARAS) by using diffusion tensor tractography (DTT) in patients with traumatic brain injury (TBI).

  • Hyung Jun Tak‎ et al.
  • BMC neurology‎
  • 2014‎

Ataxia due to injury of the cortico-ponto-cerebellar tract in patients with mild traumatic brain injury.

  • Sung Ho Jang‎ et al.
  • Medicine‎
  • 2021‎

The cortico-ponto-cerebellar tract (CPCT) is involved in coordination of movement; injury of the CPCT can therefore be accompanied by ataxia. In this study, using diffusion tensor tractography (DTT), we investigated injury of the CPCT in patients with mild traumatic brain injury (TBI).
