“…MRI is superior to CT in detecting axonal injury, small areas of contusion, and subtle neuronal damage. 49,50 Studies have shown that CT missed approximately 10 -20% of abnormalities seen on MRI. 51,52 Moreover, MRI is better at imaging the brainstem, basal ganglia, and thalami.…”

“…However, although the greater sensitivity of MRI is helpful in the subacute and chronic settings, it has not been established whether finding the additional lesions that MRI can detect would significantly change acute management of head trauma. 44,50,53 Moreover, white matter changes can be found in a large percentage of healthy middle-aged individuals.…”

Summary: Traumatic brain injury (TBI) is a common and potentially devastating clinical problem. Because prompt proper management of TBI sequelae can significantly alter the clinical course especially within 48 h of the injury, neuroimaging techniques have become an important part of the diagnostic work up of such patients. In the acute setting, these imaging studies can determine the presence and extent of injury and guide surgical planning and minimally invasive interventions. Neuroimaging also can be important in the chronic therapy of TBI, identifying chronic sequelae, determining prognosis, and guiding rehabilitation.

“…The sensitivity of CT scans is adequate to observe acute intracerebral haematoma or bone fracture, but it is not high enough to detect diffuse axonal injury (DAI), [6][7][8][9][10] which is present in 90% of patients with sTBI and largely impacts their outcome. 11,12 MRI is superior to CT in detecting DAI lesions.…”

Objective: The aim of this study was to evaluate multisequence 3.0-T MRI in the detection of severe traumatic brain injury (sTBI) and in predicting the outcome. Methods: 32 patients with sTBI were prospectively enrolled, and multisequence 3.0-T MRI was performed 4-8 weeks post injury. Quantitative data were recorded on each sequence. The ability to display the parenchymal lesions was compared with that of 64-slice spiral CT. The clinical and radiological results were correlated with the Glasgow Outcome Scale Extended scores 6 months after injury. Results: 3.0-T MRI could display more lesions than CT, especially when the lesion was deeply located. The lesion volumes and diffuse axonal injury (DAI) scores were different between good and poor outcome groups on fluid attenuated inversion recovery (p , 0.05). The apparent diffusion coefficient (ADC) values of the splenium of the corpus callosum and brain stem were also different (p , 0.05). Patients with unfavourable outcome showed a significantly higher volume of haemorrhage on susceptibility-weighted imaging than those with favourable outcomes and had haemorrhages generally located more deeply. Logistic regression analysis revealed that the location of haemorrhage and the ADC values of the splenium of the corpus callosum were independent risk factors for poor outcome, with an overall predictive accuracy of 91.4%. Conclusion: The joint use of conventional and advanced sequences of 3.0-T MRI can comprehensively detect the pathological changes occurring after sTBI. Haemorrhagic and non-haemorrhagic DAIs in deep structures strongly suggest poor outcome. Advances in knowledge: This article improves the understanding of advanced MRI sequences in the detection of patients with sTBI and prediction of prognosis.

“…MRI is very sensitive and accurate in diagnosing pathologies in brain injury patients. In particular, MRI is helpful in the sub-acute and chronic (or post-acute) settings, since MRI is superior to CT in detecting axonal injury, small areas of contusion and subtle neuronal damage (Ogawa et al 1992). It is also better at imaging the brainstem, basal ganglia and thalamus (Lee, Newberg 2005).…”
