abstract = {PURPOSE: To explore the role of single-photon emission CT (SPECT) in initial diagnostic evaluation of patients with mild traumatic brain injury (MTBI) and to identify subgroups in which it may serve as a useful diagnostic tool. MATERIALS AND METHODS: Patients with MTBI seen during a 14-month period were prospectively included in this study. All patients had a CT of head within 12 hours of injury and SPECT by using technetium Tc99m ethyl cysteinate dimer (Tc99m-ECD) within 72 hours of injury. Both SPECT and CT findings were compared with clinical features such as posttraumatic amnesia (PTA), postconcussion syndrome (PCS), and loss of consciousness (LOC). RESULTS: Ninety-two patients with MTBI underwent SPECT in the study period. There were 28 children and 64 adults, with male-to-female ratio of 4.5 to 1. CT findings were abnormal in 31 (34%) and SPECT in 58 (63%). The most common abnormality was hypoperfusion in the frontal lobe(s) in adults and the temporal lobe in children. A significantly higher number of perfusion abnormalities were seen in patients with PTA (P = .03), LOC (P = .02), and PCS (P = .01) than in patients without these symptoms. Compared to CT, SPECT had a much higher sensitivity for detecting an organic basis in these subgroup, of patients (P \< .05). CONCLUSION: Tc99m-ECD SPECT can be used as a complementary technique to CT in initial evaluation of patients with MTBI. It is particularly useful in patients having PCS, LOC, or PTA with normal CT scan.},

abstract = {BACKGROUND: The purpose of this manuscript is to present the findings in the largest series of SPECT brain perfusion imaging reported to date for mild or moderate traumatic brain injury. PATIENTS AND METHODS: This is a retrospective evaluation of 228 SPECT brain perfusion-imaging studies of patients who suffered mild or moderate traumatic brain injury with or without loss of consciousness (LOC). All patients had no past medical history of previous brain trauma, neurological, or psychiatric diseases, HIV, alcohol or drug abuse. The patient population included 135 males and 93 females. The ages ranged from 11-88 years (mean 40.8). The most common complaints were characteristic of the postconcussion syndrome: headaches 139/228 (61%); dizziness 61/228 (27%); and memory problems 63/228 (28%). LOC status was reported to be positive in 121/228 (53%), negative in 41/228 (18%), and unknown for 63/228 (28%). RESULTS: Normal studies accounted for 52/228 (23%). For abnormal studies (176/228 or 77%) the findings were as follows: basal ganglia hypoperfusion 338 lesions (55.2%); frontal lobe hypoperfusion 146 (23.8%); temporal lobes hypoperfusion 80 (13%); parietal lobes hypoperfusion 20 (3.7%); insular and or occipital lobes hypoperfusion 28 (4.6%). Patients' symptoms correlated with the SPECT brain perfusion findings. The SPECT BPI studies in 122/228 (54%) were done early within 3 months of the date of the accident, and for the remainder, 106/228 (46%) over 3 months and less than 3 years from the date of the injury. In early imaging, 382 lesions were detected; in 92 patients (average 4.2 lesions per study) imaging after 3 months detected 230 lesions: in 84 patients (average 2.7 lesions per study). CONCLUSIONS: Basal ganglia hypoperfusion is the most common abnormality following mild or moderate traumatic brain injury (p = 0.006), and is more common in patients complaining of memory problem (p = 0.0005) and dizziness (p = 0.003). Early imaging can detect more lesions than delayed imaging (p = 0.0011). SPECT brain perfusion abnormalities can occur in the absence of LOC.},

abstract = {PRIMARY OBJECTIVE: The purpose of this study was to examine the prevalence of day-of-injury intracranial abnormalities in a large sample of patients with mild head injuries who were admitted to a Trauma Service. METHODS AND PROCEDURES: There were 912 patients who obtained admission Glasgow Coma Scale (GCS) scores of 13-15. MAIN OUTCOMES AND RESULTS: The base rate of complicated mild head injuries (i.e. abnormal CT scans) in this sample was 15.8%. However, nearly 25% of the sample, most of whom had very mild injuries, did not receive CT-scans. Therefore, the actual prevalence is more likely in the range 16-21%. There was a tremendous overlap in injury characteristics between patients with complicated and uncomplicated mild head injuries. None the less, there were modest, yet statistically significant, relationships between the presence of intracranial abnormalities and lower GCS scores, greater frequency of positive loss of consciousness, greater frequency of skull fractures, and lower GOAT scores.},

abstract = {Patients with traumatic brain injury (TBI) frequently exhibit varied forms of visual system dysfunction including: binocular, oculomotor, accommodative, refractive error shift, visual field loss, and visual perceptual deficits. A 5-year collaborative study between optometry and ophthalmology was initiated to follow documented mild TBI patients utilizing diagnostic methods to assess the quantity and quality of visual system deficits and recovery. A group of patients with mild TBI receiving optometric rehabilitation were compared with a group of age-matched, gender-matched, and headsize-matched TBI patients not receiving such treatment. Eighteen patients diagnosed with mild TBI underwent a treatment regimen of optometric rehabilitation (group I); 32 patients diagnosed with mild TBI did not receive optometric rehabilitation (group II). Pattern visually evoked cortical potential (VECP) testing and electroretinography (ERG) evaluation were utilized initially, repeated 6-12 months later and then 12-18 months after baseline. All TBI patients' VECP and ERG results were compared to age-matched, headsize-matched controls. Once the ERG had been used to exclude retinal involvement, identification of visual pathway dysfunction was possible with the VECP. Full-field ERG results in all groups were not remarkable and not sensitive for patients with mild TBI. Initial testing results revealed that 72% of those TBI patients in group I demonstrated VECP waveform abnormalities and 81% of those patients in group II showed waveform dysfunction. In the testing performed 12-18 months later, 38% of group I TBI patients, after receiving a treatment regimen of optometric rehabilitation, showed VECP waveform abnormalities; 78% of group II TBI patients demonstrated waveform abnormalities. VECP evaluation in patients with mild TBI can provide a useful and reliable tool for objective assessment of visual system deficit and recovery. Significant differences in visual system recovery were shown when comparing group I and group II.},

Motor normalcy returned in about 10 seconds, and normal memory in an hour. There were immediate electroencephalogram and transmitter changes. All these returned to normal within an hour following 1 or 20 such concussions. We could find no light or electron microscopic changes. Halothane anesthesia precludes measurement of coma and introduces distortion of metabolite findings. To date our findings indicated concussion at this level is completely reversible.},

abstract = {The use of skull radiography in the initial evaluation of minor head injured patients is controversial. In an attempt to evaluate its benefits, a retrospective study of 566 cases subjected to skull radiography following close minor head trauma (Glasgow Coma Scale 13-15), is presented. A skull fracture (linear vault, depressed or base of skull) was present in 64 (11%) cases. Only three (5%) who were found to have a skull fracture on skull radiography developed an intracranial injury which required surgery. Intracranial injuries developed in 19 (3%) cases and were followed by surgery in six (32%). All, except for one case, had a decreased level of consciousness and a Glasgow Coma Scale less than 15, few had focal neurological deficits. Management had not been altered by the results of skull radiography in any of the cases. We concluded that skull radiographs are unnecessary for the decision process in closed minor head injury because management decisions are based primarily on a careful neurological examination. When intracranial injuries are a concern, a CT scan should be obtained.},

MRI was conducted with a Technicare Teslacon system using a 5.0 kG (0.5 T) magnetic field. Clinically, patients varied from those with mild concussions without focal neurological signs to those with severe neurological dysfunction including posttraumatic coma. MRI was superior to CT in imaging 23 of 41 extracerebral fluid collections, both in estimating the size of the collections and in diagnosing small collections. MRI was also superior to CT in distinguishing chronic subdural hematomas from hygromas. Further, MRI was superior to CT in visualizing nonhemorrhagic contusion in 15 of 21 lesions. Because of the potential failure of MRI to diagnose acute subarachnoid or acute parenchymal hemorrhage, CT remains the procedure of choice in diagnosing head injury less than 72 hours old.},
