Pulmonary intravascular lymphoma detected by FDG-PET.

A 69-year-old woman visited our hospital with a 2-month history of general fatigue, high fever, and dyspnea. Physical examination showed no abnormalities in superficial lymph nodes or respiratory sound. A chest computed tomography scan showed diffuse mild ground-glass attenuation in bilateral lung fields, whereas FDG-PET revealed intense uptake of FDG throughout the lung.

Dark-field transmission electron microscopy for a tilt series of ordering alloys: toward electron tomography.

Here we show a technique to obtain a tilt series of dark-field (DF) transmission electron microscopy (TEM) images in ordering alloys for tomographic three-dimensional (3D) observations. A tilt series of DF TEM images of D1a-ordered Ni4Mo precipitates in a Ni-Mo alloy was successfully obtained by adjusting a diffraction condition for a superlattice reflection from the Ni4Mo precipitates. Since the superlattice reflection usually has a long extinction distance, dynamic diffraction effects such as thickness fringes can be suppressed to some extent with precise realignment of the diffraction condition. By using the tilt series of the DF TEM images, we attempted a computed TEM tomography to visualize 3D shapes and positions of the precipitates.
