BACKGROUND Information on the clinical features of the severe acute respiratory syndrome (SARS) will be of value to physicians caring for patients suspected of having this disorder. METHODS We abstracted data on the clinical presentation and course of disease in 10 epidemiologically linked Chinese patients (5 men and 5 women 38 to 72 years old) in whom(More)
The clinical utility of dual sequence (T1- and T2-weighted) magnetic resonance (MR) imaging in estimating liver iron concentration (LIC) in 32 transfusion-dependent beta-thalassaemia major (24 females; age 18.5+/-5.9 years) patients on desferrioxamine was evaluated. Signal intensity ratios (SIR) between liver, spleen and pancreas to psoas muscle were(More)
PURPOSE To use qualitative and quantitative computed tomography (CT) to test the hypothesis that impaired lung function with silicosis is due to progressive massive fibrosis (PMF) and associated emphysema. MATERIALS AND METHODS Seventy-six men with silicosis underwent volumetric and thin-section CT of the thorax. Lung function, Borg scale dyspnea grade,(More)
OBJECTIVE The efficacy of transarterial chemoembolization (TACE) in prolongation of survival is controversial. We conducted a comparative study to determine whether TACE treatment had any survival benefit for patients with unresectable hepatocellular carcinoma (HCC) and with relatively preserved liver function. METHODS In all, 96 patients with(More)
The aim of the study was to evaluate white-matter (WM) diffusion anisotropy in medulloblastoma survivors after cranial irradiation and chemotherapy using voxel-based analysis with SPM99 and fractional anisotropy (FA) histogram-derived indices, and to identify quantitative indices for detecting and monitoring children with treatment-induced white-matter(More)
Malignant lymphoma of the central nervous system is usually confined within the cranium, with primary involvement of the spinal cord and nerve roots being very rare. The occurrence of primary lymphoma in the cauda equina in a 16-year-old Chinese male is reported. Contrast enhancement during magnetic resonance imaging is useful in accurately demonstrating(More)
BACKGROUND Non-small cell lung cancer (NSCLC) is a leading cause of cancer deaths, and over 60% of patients present with advanced stages. Although polysaccharide peptides (PSP), isolated from the fungus Coriolus versicolor, have been reported to have anti-tumor effects, its clinical efficacy has not been properly evaluated. METHODS Double-blind(More)
OBJECTIVE Nasal T-cell/natural killer cell lymphoma is a new clinicopathologic entity with a characteristic immunophenotypic profile and distinct clinical features. This study describes the radiologic features of nine cases of proven nasal T-cell/natural killer cell lymphoma. CONCLUSION Nasal T-cell/natural killer cell lymphoma is often a locally(More)
OBJECTIVE This study was conducted to summarize the clinical and radiologic presentations including pertinent imaging features of granulocytic sarcoma, a rare extramedullary tumor of acute myeloid leukemia, in 11 adult patients. CONCLUSION In patients in our study, the clinical and radiologic manifestations of granulocytic sarcoma were variable and(More)
