Introduction: Traumatic brain injury (TBI) is a common problem nowadays and a significant number of traumatic patients are involved in mental and cognitive disorders, the most common CT finding is small hemorrhagic lesions in cerebral white matter, these hemorrhagic lesions can be effective in occurrence of neuropsychiatric symptoms in Post Traumatic Stress Disorder patients. Many diagnostic modalities such as T2GE and T2SE have been employed to detect brain hemorrhagic lesions. The goal of this study is the comparison between these two sequences for diagnosis of brain hemorrhagic lesions in patients with a history of previous head trauma that were referred with neuropsychiatric symptoms.
Objective: The comparison between abnormal findings in T2SE and T2GE sequences in chronic traumatic brain lesions in MRI.
Method: Thirty patients who had a history of previous head trauma, referred to neurosurgeon because of neuropsychiatric symptoms (PTSD) were prospectively studied using MRI. Then the correlation between T2GE and T2SE sequences finding and patient‘s clinical symptoms were analyzed by Wilcoxon Signed Ranks Test (all the patients had these symptoms at least three months after head trauma).
Result: 80% of patients had hemorrhagic lesions in T2GE which was significantly (p<0/01) greater than those detected by T2SE(23%).Therefore T2GE is significantly better than T2SE in detecting the cause of clinical symptoms in traumatic patients (p<0/01).
Conclusion: T2GE was found to be more useful for evaluating the neuropsychiatric symptoms in patients with previous history of head trauma so this sequence could play a major role in diagnosis and treatment of these patients specially in their legal problems .Thus we recommend that this sequence to be a routine method for evaluation of chronic traumatic patients.
