OBJECTIVE The aim of our study was to describe 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) findings of a localized form of bronchioloalveolar carcinoma and to compare those findings with other cell types of lung cancer. SUBJECTS AND METHODS FDG PET was performed in 48 patients with lung cancer. The patients had carcinomas of various(More)
STUDY OBJECTIVES To define the clinical characteristics of the patients showing bronchoscopic findings of bronchial narrowing or obliteration with black pigmentation on overlying mucosa (we named this finding as "anthracofibrosis"), and to determine the association of anthracofibrosis with tuberculosis. PATIENTS AND METHODS The subjects of this study(More)
OBJECTIVE To assess the utility of CT in the evaluation of pulmonary tuberculosis in patients without AIDS. PATIENTS AND METHODS This-section CT scans for suspicion of pulmonary tuberculosis were obtained from 226 patients. A total of 38 patients were excluded; the reasons were unavailability of final results (n = 18), patient unavailability for follow-up(More)
PURPOSE The purpose of this work was to demonstrate the initial and follow-up radiologic findings of squalene-induced extrinsic lipoid pneumonia. METHOD Follow-up chest radiographs (n = 9) and high-resolution CT scans (n = 3) as well as initial radiographs (n = 9) and CT scans (n = 8) were obtained in nine patients with squalene-induced extrinsic lipoid(More)
We have isolated and characterized a rat brain cDNA clone which encodes a new protein of 474 amino acids in length which contains two C2 domains structurally homologous to those present in synaptotagmins. The overall amino acid identity in C2 domains between this protein and the synaptotagmins is 36-44%. This protein also contains 3 putative consensus(More)
An elevated serum lactate level is associated with morbidity and mortality in patients with severe sepsis and septic shock. In patients with hepatic dysfunction, however an elevated serum lactate level may be due to either impaired lactate clearance or excessive production. Thus, we evaluated whether the initial serum lactate level was also associated with(More)
The advantage of volumetric computed tomography in the thorax is the possibility of acquiring both multiplanar and three-dimensional (3D) images, thus enabling precise diagnosis and evaluation of extent of disease involving the airways. Multiplanar and 3D images appear to be useful for global understanding of the status of the tracheobronchial tree,(More)
Typical CT findings of active postprimary pulmonary tuberculosis include centrilobular nodules and branching linear structures (tree-in-bud appearance), lobular consolidation, cavitation, and bronchial wall thickening. The CT findings of inactive pulmonary tuberculosis include calcified nodules or consolidation, irregular linear opacity, parenchymal bands,(More)
OBJECTIVE The purpose of our study was to describe high-resolution CT findings of nonspecific interstitial pneumonia with fibrosis and to compare findings seen on CT with pathologic findings. MATERIALS AND METHODS High-resolution CT findings of biopsy-proven non-specific interstitial pneumonia with fibrosis from 23 consecutive patients (one man and 22(More)
