Ultrastructural Examination and Technical Developments

Histopathological and ultrastructural examination of optic nerve sheath decompression.

Both optic nerves were obtained at autopsy from a 28-year-old man with a 2 year history of idiopathic intracranial hypertension who had undergone bilateral optic nerve sheath decompression 14 days before death. Histopathological and ultrastructural examination of the tissue revealed fibroblasts localised to the sites of fenestration. Adipose tissue was also adherent to the optic nerve pia in ar...

Paraconsistent Logics and Paraconsistency: Technical and Philosophical Developments

Coronary magnetic resonance angiography: technical developments and clinical applications.

Magnetic resonance angiography (MRA) is a promising method for noninvasive coronary artery imaging. The interesting features of coronary MRA are its non-invasive nature, the absence of ionizing radiation, and the possibility of imaging the coronary arteries without exogenous contrast. Moreover, three-dimensional volume information and tomographic image planes in any direction can be obtained. T...

Recent developments in choledochoscopy: technical and clinical advances

Peroral cholangioscopy has become an important tool in the diagnosis and treatment of a variety of biliary diseases, ranging from indeterminate biliary strictures to bile duct stones. Although the first cholangioscopy was performed in the 1970s, recent technological advances have provided us with cholangioscopes that yield high-resolution images, possess single-operator capability, and have ult...
