Automated classification of multispectral MR images using unsupervised constrained energy minimization based on fuzzy logic

Constrained energy minimization (CEM) has proven highly effective for hyperspectral (or multispectral) target detection and classification. It requires a complete knowledge of the desired target signature in images. This work presents ?Unsupervised CEM (UCEM),?

Bubble growth and collapse in pre-fermented doughs during freezing, thawing and final proving

The formation of large bubbles was observed by MRI during freezing. This was attributed to the compression of gases in a structure that cannot globally deform (due to the frozen ?shell?), the consecutive rupture of dough films and the coalescence of neighbouring bubbles.

MRI of the pharynx in ischemic stroke patients with and without obstructive sleep apnea

Obstructive sleep apnea (OSA) is common after stroke and associated with poor stroke outcomes. Whether OSA after acute stroke is caused by anatomic, physiologic, or both etiologies has not been studied.

3D Mapping of brain differences in native signing congenitally and prelingually deaf subjects

In the prelingual and congenital deaf, functional reorganization is known to occur throughout brain regions normally associated with hearing. However, the anatomical correlates of these changes are not yet well understood.

Diffusion tensor imaging of renal ischemia reperfusion injury in an experimental model

Renal ischemia reperfusion injury (IRI) is a major cause of acute renal failure. It occurs in various clinical settings such as renal transplantation, shock and vascular surgery. Serum creatinine level has been used as an index for estimating the degree of renal functional loss in renal IRI.

Modern imaging of the infarct core and the ischemic penumbra in acute stroke patients: CT versus MRI

Thrombolysis has become an approved therapy for acute stroke. However, many stroke patients do not benefit from such treatment, since the presently used criteria are very restrictive, notably with respect to the accepted time window.
