PURPOSE To assess whether relative cerebral blood volume (rCBV) can provide information to reliably evaluate the stages of late delayed radiation-induced brain injury. MATERIALS AND METHODS Forty patients diagnosed with late delayed radiation-induced brain injury were enrolled. The patients were examined using a 1.5T magnetic resonance imaging (MRI)(More)
RATIONALE Hypoplasia with an intact posterior arch of the atlas and ossification of the posterior atlantoaxial membrane (PAAM) are individually rare. PATIENT CONCERNS The patient presented with a 6-month history of progressive weakness and paresthesia of his lower extremities. DIAGNOSES Cervical myelopathy resulting from atlas hypoplasia and(More)
Gibbs random field models describe image textures in terms of geometric structure and energy of pixel interactions. The interaction means statistical interdependence of signals, the structure is given by characteristic pixel neighbourhoods, and the energy depends on signal cooccurrences over the neighbourhoods. In translation invariant textures all the(More)
This paper describes the basic steps of a new technique, called bunch sampling, that enables the realistic synthesis of spatially homogeneous textures. A geometric shape of the bunch (acting as a texel) and spatial placement grid governing relative positions of the bunches are estimated from the training texture by using a generic Gibbs random field texture(More)
