A total of 31 adult patients with moderate and severe head injury were assessed clinically on admission for Glasgow Coma Scale (GCS) and short test of mental status (STMS) on follow-up and compared to their initial and follow up CT scan. Good predictors were admission GCS, midline shift, volume of ...

BACKGROUND: Patients with minimal head injury (MHI) and intracranial bleed (ICB) detected on cranial computed tomography (CT) scan routinely undergo a repeat cranial CT within 24 hours after injury to assess for progression of intracranial injuries. While this is clearly beneficial in patients with a deteriorating neurologic status, it is ...

INTRODUCTION: Despite advances in trauma care, significant morbidity and mortality exists which could be reduced if all injuries were immediately identified. Two treatable factors are hypoxia and hypovolaemia which may occur secondary to haemorrhage into the chest and abdomen. Pneumothorax is also a frequent cause of preventable trauma death. Clinical ...

A case is presented of unilateral internuclear ophthalmoplegia as an isolated sequel of minor head trauma, which eventually ...

MR imaging is a highly valuable tool in the evaluation of ligamentous injuries of the elbow. Proper coil selection, patient positioning, and pulse sequence parameters are essential for optimization of image quality. Clinical evaluation of ligamentous injuries is often difficult and visualization at surgery may be limited. MR imaging can ...

BACKGROUND: Repeat head computed tomography (CT) is standard practice for head-injured patients at many trauma centers. Utilization of CT has increased over time, yet effects on outcome and associated risks are unknown. We systematically reviewed the literature to determine the incidence of progression of injury on repeat CT and resulting ...

Proton magnetic resonance spectroscopy (MRS) is being used to evaluate individuals after acute traumatic brain injury. These studies have shown that changes in certain brain metabolites are associated with poor neurologic outcomes. The majority of MRS studies have been obtained relatively late after injury, but there have been a few ...

Cricotracheal separation (CTS) is an uncommon injury, with a high index of suspicion required to establish the diagnosis. Computerized tomography (CT) plays a role in diagnosis but cannot necessarily be relied upon. Bilateral recurrent laryngeal nerve (RLN) palsies are usually associated with this type of injury. We recently treated a ...

We report a 5-year-old child with pancreatic trauma from a blunt abdominal injury that was monitored with contrast-enhanced sonography. Unenhanced US failed to demonstrate the abnormality that was recognized by CT and MRI. The injury was well demonstrated by contrast-enhanced US which was therefore used for follow-up until its healing.

The aim of this study was to investigate the visibility of traumatic brain lesions on conventional magnetic resonance images (MRI) in early and late phase.
