Multimodal MR imaging of acute and subacute experimental traumatic brain injury: Time course and correlation with cerebral energy metabolites.
Traumatic brain injury (TBI) is one of the leading causes of death and permanent disability world-wide. The predominant cause of death after TBI is brain edema which can be quantified by non-invasive diffusion-weighted magnetic resonance imaging (DWI). ⋯ The partial ATP reduction was interpreted to be partially caused by a loss of neurons in parallel with transient dilution of the regional ATP concentration by pronounced vasogenic edema. The normalization of energy metabolism after 7 days was likely due to infiltrating glia and not to recovery. The MRI combined with metabolite measurement further improves the understanding and evaluation of brain damages after TBI.

Case ReportsSmall bowel feces sign in association with occlusive mesenteric ischemia.
Small bowel feces sign (SBFS) is a computed tomography (CT) finding that appears as fecal like material in dilated small bowel loops. This sign is usually seen in association with gradually progressive small bowel obstruction. ⋯ We put forward a suggested alternative mechanism to the appearance of this sign in association with mesenteric ischemia. The SBFS might have the potential to serve as an early sign of mesenteric ischemia on CT scan.

Case ReportsSelective embolization of the splenic vein for shunt-preserving disconnection of the portal and systemic circulation: report of two cases.
In carefully selected patients with portosystemic encephalopathy, it is possible to safely disconnect the portal and systemic circulation while preserving the shunt. We report two patients with chronic hepatitis and recurrent episodes of hepatic encephalopathy due to a portosystemic shunt who underwent successful selective embolization of the splenic vein for a shunt-preserving disconnection of the portal and systemic circulation via the percutaneous transhepatic route.
