Regions of interest-based discriminant analysis of DaTSCAN SPECT and FDG-PET for the classification of dementia.

Purpose: Neuroimaging is increasingly used to support the clinical diagnosis of patients with cognitive impairment. Dopamine transporter (DAT) imaging, such as DaTSCAN SPECT, tests the integrity of the nigrostriatal pathway, whereas FDG-PET identifies typical patterns of cortical and subcortical hypometabolism. The aim of this study was to assess the relative contribution of DAT and regional glucose metabolism imaging to the differential diagnosis.

A rapid method based on front-face fluorescence spectroscopy for the monitoring of the texture of meat emulsions and frankfurters.

In order to investigate the potential of fluorescence spectroscopy to characterise meat emulsions and frankfurters, a split-plot design comprising three factors at three levels each, i.e. fat/lean ratios (0.

[Dolichoectasic cerebral arteries and aneurysm of the abdominal aorta. Double vascular rupture, favourable course].

The authors report a case of dolichoectasic intracranial arteries associated with an aneurysm of the abdominal aorta. The patient presented with a double hemorrhagic vascular rupture, the abdominal aortic aneurysm being operated on as an emergency, with a favorable outcome. The cerebral and aortic angiograms showed extension of the pathological process to the large caliber arteries.

["Partial diastematomyelia" in an adult with a posterior bony spur].

Diastematomyelia is rarely diagnosed in adulthood, and apparently 8 cases only have been reported. We report here a 59 year-old woman who recently experienced backpain with irradiations to lower limbs, mild distal weakness and sphincter disturbances. Diastematomyelia was suspected because of a history of lumbar "cutaneous malformation" operated when 4 month old, and a hairy patch over the lumbar spine.
