In comparison to pre-injury scans, post-injury MR scan analysis demonstrated significant ventricular volume increase which is considered a measure of the degree of diffuse axonal injury. Most important, the trauma induced degenerative effects appeared to be quite complete by 42 days post-injury as there was little further degeneration that occurred between the 6 week and 10 month post-injury scans. This study demonstrates that in humans the majority of gross trauma-induced degenerative changes are complete by 6 weeks post-trauma.

The DOI VBR did not differ significantly from the medical controls, but both (DOI and medical control VBR) differed significantly from post-injury VBR. Additionally, a case study is presented wherein MR imaging studies were obtained prior to TBI so that a direct comparison of pre-injury to DOI to post-injury changes could be made. In this case the pre-injury and DOI VBRs were within approximately 9% of each other. In contrast, the post-injury VBR demonstrated over a 100% increase in comparison to either the pre-injury or DOI scan. This case and another case are illustrated using three-dimensional image analysis to represent ventricular change over time. These cases, along with the similarity of the DOI VBR with the medical controls, suggests that the DOI VBR can be utilized as an estimate or index of pre-injury ventricle/brain morphology. This will permit the use of DOI CT data for within-subject designs in TBI research that examines the course of degenerative changes over time.

The day-of-injury scan represented an adequate estimate of pre-injury morphological status based on cross-sectional area measurements of the ventricular system. By comparing pre-injury CT measurements with those obtained on the day of injury, 2 days post-injury and 16 months post-injury via assessing cross-sectional area of select ventricular regions (e.g. anterior and temporal horns, body and third ventricle) it was demonstrated that the TBI induced over a 50% ventricular expansion. Such ventricular expansions are felt to provide some index into diffuse axonal injury which may provide a means of eventually quantifying the degree of structural damage secondary to TBI. This analysis also demonstrated that there were no significant differences between selected cross-sectional ventricular areas in the 15 day and 16 month post-injury MR scans. This finding suggests that the degenerative effects of TBI have a rapid onset and are becoming readily apparent by 15 days post-injury. Thus, early imaging may provide a good index of long-term morphological outcome in TBI.

Research paper thumbnail of Neuropsychological outcome and quantitative image analysis of acute haemorrhage in traumatic brain injury: Preliminary findings

Brain Injury, 1994

Haemorrhagic lesion volume was associated with severity of injury. However, the number of petechial haemorrhages was not reliably associated with any of the clinical outcome measures. Likewise, despite the use of detailed morphometric methods to quantify volume, the acute lesion size did not significantly relate to neuropsychological sequelae. Furthermore, brain quadrant localization methods did not enhance outcome prediction. These results are discussed in the context of acute lesion analysis contrasted with chronic TBI-induced neuropathological changes associated with neuropsychological outcome.

The loss of vessel contrast due to slow flow-related signal saturation can be compensated by the Ti reduction obtained from the use of an MR contrast agent, such as Gd-DTPA. The vesselfbackground signal-difference-to-noise ratio (SDNR) is shown to strongly depend on the imaging parameters, as well as on the time course of the blood Ti values obtained from the contrast injection. Specifically, it was found that vessel SDNR increases almost linearly with TR, if the sampling bandwidth is reduced proportionately.

We report on two quantitative MR studies: study 1 addressed age-related changes of the temporal lobe in subjects aged 16-72 years; information obtained in this study provided a normative database for comparison with findings in 118 patients with TBI who were included in study 2. We expected stable morphology in healthy subjects and trauma-related atrophy in patients with TBI. METHODS: MR multispectral tissue segmentation was used to calculate bilateral temporal lobe gyrus and sulcus, sylvian fissure CSF, hippocampus, and temporal horn volumes and to measure the white matter (WM) temporal stem. RESULTS: With normal aging, gyral volume remained stable, decreasing approximately 0.26% per year (total, Ϸ11%). Sulcal CSF volume doubled. Hippocampal volume decreased (minimally, significantly); temporal horn volume increased (not significantly) and was minimally related to hippocampal volume. WM measurements were constant. Trauma changed morphology; WM measures decreased. Gyral volumes were not different between the groups. In TBI, CSF volume increased significantly, was most related to reduced WM measurements, and was relatively independent of gyral volume. Temporal horn dilatation was related more to WM atrophy than to hippocampal atrophy. In TBI, subarachnoid sulcal and temporal horn CSF volumes were most related to WM atrophy, which was relatively independent of gyral volume; gyral and hippocampal volumes and WM measures were related to memory performance. CONCLUSION: Age-related changes cause minimal temporal lobe gyral, hippocampal, temporal horn, and WM atrophy. Only subarachnoid sulcal CSF volume changed robustly. Trauma produced disproportionate WM loss associated with increased temporal horn and sulcal CSF volumes; it caused substantial hippocampal atrophy, which was related to memory impairment. Gyral volume did not decrease, although it was related to memory performance.

Ninety-six healthy volunteers and 94 patients with traumatic brain injury were examined with coronal intermediate and T2-weighted MR imaging. Multispectral segmentation and volume analyses were performed. The volumetry of the hippocampus and temporal horn was characterized in the control subjects. Volumetric measures in a group of patients with traumatic brain injury who had received MR imaging 3 months or less after injury were compared with measurements in other patients in the chronic phase of recovery. The relationship between neuropsychological testing and volumetric measures was analyzed with particular emphasis on the correlation between cognitive outcome and hippocampal and temporal horn volumes. No significant age group differences were found in the normative group from age 16 to 65. Lef...

Axial intermediate and T2-weighted MR images of 123 patients with traumatic brain injury were quantified using a multispectral segmentation algorithm. Measurements were corrected for differences in age, sex, and head size using a previously reported normative database. Brain morphology was compared across groups formed on the basis of chronicity of injury. Cognitive functioning and severity of injury were statistically correlated with brain measurements. Time-dependent expansion of CSF spaces and decreases in brain volume were observed. Increases in ventricular CSF volume, particularly in the temporal horns and third ventricle, preceded subsequent changes in total brain and subarachnoid CSF. High and moderate ...

This database is presented as a reference for future studies comparing pathologic states. One hundred ninety-four healthy subjects, ranging in age from 16 to 65 years, received standard axial intermediate- and T2-weighted spin-echo MR images. Multispectral segmentation and volume analysis were performed using ANALYZE. Normative volumetric estimates, both uncorrected and corrected for differences in total intracranial volume, were obtained for all subjects and presented by decade and sex. Age-related cerebrospinal fluid changes were evident for both male and female subjects. Most gender differences were eliminated by correction for d...
