The purpose of this study was to determine the diagnostic sensitivity and specificity helical CT with sagittal coronal reformatted images in detecting diaphragmatic rupture after blunt trauma.Chest abdominal scans obtained 41 patients suspected injury major trauma were reviewed by three observers who unaware surgical findings. Coronal for each patient as well. Findings consistent injury, such waistlike constriction viscera (i.e., "collar sign"), intrathoracic herniation contents,...
The purpose of this retrospective study was to evaluate the use contrast-enhanced CT show sites active hemorrhage as a guide for surgical or angiographic treatment in patients sustaining blunt abdominal pelvic trauma. Twenty-six scans were reviewed compare location locations extravasated contrast material (representing hemorrhage) detected on with site determined by surgery (eight patients), angiography (14 autopsy (one patient). (The three remaining had no additional studies done.)...
Mild traumatic brain injury (mTBI) is often occult to conventional imaging techniques. However, there growing evidence that mTBI patients who lack of structural intracranial may develop post-concussive syndrome (PCS). We investigated longitudinal alterations in resting state functional connectivity (rs-FC) networks a population 28 compared matched control participants. Rs-FC and cerebral blood flow (CBF) within the nodes Default Mode Network (DMN) Task Positive (TPN) were assessed at three...
The nontherapeutic laparotomy rate in penetrating abdominal trauma remains high and the morbidity these cases is approximately 40%. Selective management, rather than mandatory laparotomy, has become a popular approach both stab wounds gunshot wounds. advent of spiral technology stimulated reassessment role computed tomography (CT) many aspects care. We prospectively investigated current utility triple-contrast CT as diagnostic tool to facilitate initial therapeutic management decisions torso...

To investigate longitudinal diffusion tensor imaging (DTI) and kurtosis (DKI) changes in white grey matter patients with mild traumatic brain injury (mTBI).A prospective case-control study.DKI data was obtained from 24 mTBI along cognitive assessments within 10 days, 1 month 6 months post-injury compared age-matched control (n¼ 24). Fractional anisotropy (FA), mean diffusivity (MD), radial (l(r)), (MK) (Kr) were extracted the thalamus, internal capsule corpus callosum.Results demonstrate...

The aim of this retrospective study was to evaluate the usefulness MR imaging in excluding or confirming diagnosis diaphragmatic injury after blunt trauma.MR studies were performed 16 patients with trauma and indeterminate radiographs chest suspicious for but not diagnostic injury. T1-weighted images obtained all patients, fast gradient-echo pulse sequence 11 patients. results before those during out-patient follow-up, including radiography thoracoabdominal CT scanning, reviewed evidence...
OBJECTIVE. The objective of this study was to determine the CT findings traumatic lumbar hernia in 15 patients and discuss mechanism treatment injury.
Chance-type fractures are subtle unstable injuries that often associated with intraabdominal injuries. CT-based observations made during routine interpretations revealed involvement of a burst component to this fracture pattern and clue on the transaxial images its presence. The purpose review was determine how these features occurred in retrospective study large sample because findings influence diagnosis management.A all patients identified from University Maryland Shock Trauma Center...
The authors performed a study to determine if lesion expansion occurs in humans during the early hours after spinal cord injury (SCI), as has been established rodent models of SCI, and identify factors that might predict expansion.
In the majority of patients with mild traumatic brain injury (mTBI), tissue impairment is undetectable by computed tomography and/or structural magnetic resonance imaging. Even in confirmed cases head injury, conventional neuroimaging methods lack sensitivity predicting neuropsychological outcomes patients. The objectives this study were to (1) cross-sectionally determine deviations neurometabolic profile mTBI from healthy controls at different stages using tightly controlled examination...
Following blunt splenic injury, there is conflicting evidence regarding the natural history and appropriate management of patients with vascular injuries spleen such as pseudoaneurysms or blushes. The purpose this study was to describe current outcomes pseudoaneurysm blush.Data were collected on adult (aged ≥18 years) injury a from 17 trauma centers. Demographic, physiologic, radiographic, characteristics gathered. Management collected. Univariate multivariable analyses used determine...
Diffusion tensor imaging (DTI) has recently emerged as a useful tool for assessing traumatic brain injury (TBI). In this study, the prognostic value of relationship between DTI measures and clinical status severe TBI patients, both at time magnetic resonance (MRI), their discharge to acute rehabilitation, was assessed. Patients (n=59) admitted trauma center with closed head injuries were retrospectively evaluated after approval from institution's institutional review board, determine...
OBJECT Studies of preclinical spinal cord injury (SCI) in rodents indicate that expansion intramedullary lesions (IMLs) seen on MR images may be amenable to neuroprotection. In patients with subaxial SCI and motor-complete American Spinal Injury Association (ASIA) Impairment Scale (AIS) Grade A or B, IML has been shown approximately 900 μm/hour. this study, the authors investigated a cohort AIS A, C, D. METHODS Seventy-eight who had at least 2 MRI scans within 6 days were enrolled. Data...
The use of computed tomography (CT) to identify injury after penetrating torso trauma has become routine in the hemodynamically stable patient. diaphragm been a historically difficult structure evaluate, however, and missed injuries may result significant morbidity. With increasing multidetector row CT (MDCT), we hypothesized that would be an accurate detection modality patients with injuries.We retrospectively reviewed admission consecutive admitted for during 4-year period. scans were...
