Rothia mucilaginosa is a gram-positive coccus of the family Micrococcaceae. R. mucilaginosa is considered a part of the normal flora of the human oropharynx and upper respiratory tract and lower respiratory tract infections attributable to R. mucilaginosa are not frequent. We present a case of pneumonia, in which the R. mucilaginosa infection was diagnosed by quantitative cultures of a bronchoa...

We report the first description of CT findings of axillary tuberculous lymphadenitis confirmed by the pathological specimen. The breast cancer screening examination is one of the prime methods of detection of axillary tuberculous lymphadenitis. The most common site of axillary tuberculous lymphadenitis is the deep axilla. Screening mammography often fails to cover the whole axilla. The presence...

Radiation technology such as X-ray computed tomography (X-ray CT) is a powerful tool for materials research. Such non-destructive imaging allows us to visualize in three dimensions (3D) the internal structure of without damaging specimen. This paper thus presents our studies on application microfocus CT, synchrotron radiation and integrated microtomography diffraction (CT-XRD) method advance ce...

Synchrotron-radiation-based microcomputed-tomography (SR-μCT) is a powerful tool for yielding 3D structural information of high spatial and contrast resolution about a specimen preserved in its natural state. A large number of projection views are required currently for yielding SR-μCT images by use of existing algorithms without significant artifacts. When a wet biological specimen is imaged, ...

A 48-year-old Chinese male henhouse keeper was admitted with dyspnoea. A plain chest radiograph and CT scan indicated a solitary right lung mass with invasion to the trachea (fig 1A and B). Positron emission tomography with Ffluoro-2-deoxy-D-glucose (FDG-PET) showed accumulation in the lung mass (fig 1C). A transbronchial biopsy specimen provided a pathological diagnosis of pulmonary cryptococc...

inflammatory myofibroblastic tumor (imt) is an aggressive benign mass that may arise from various tissues and organs with a great variability of histological and clinical appearances. due to variable and nonspecific imaging findings, diagnosis of imt is not obtained before surgery. the aim of this paper is to present ct and mri findings during four-year follow-up of complete, spontaneous regres...

A 77-year-old man with a history of hemodialysis was referred due to swelling of the right groin. Enhanced computed tomography (CT) showed extravasation of the medium from the superficial femoral artery (SFA) with surrounding large hematoma. Three-dimensional CT angiography revealed rupture of SFA just distal to common femoral artery with pseudoaneurysmal formation. At an emergent surgery, SFA ...

This paper presents a method for evaluating the quality of X-ray computed tomography (CT) volume data for dimensional metrology. In the method entropy defined on the distribution of CT values of volume data is used as a criterion. For a local geometric feature of a specimen, concepts defined in GD&T are used as reference to define the evaluation area for entropy calculation. Some scannings with...

intravascular large b-cell lymphoma (ivlbcl) is a rare and aggressive subtype of systemic extranodal non-hodgkin diffuse large b-cell lymphoma (dlbcl). we report a rare case of ivlbcl who showed diffuse 18f-fluorodeoxyglucose (fdg) uptake in the lung in fdg-positron emission tomography/computed tomography (pet/ct) without respiratory symptoms or chest ct abnormalities. serum biochemical studies...
