PURPOSE To assess technical feasibility, efficacy, and complications of percutaneous computed tomography (CT)-guided transthoracic radiofrequency (RF) ablation for treating inoperable non-small cell lung cancer (NSCLC) and lung metastases. MATERIALS AND METHODS Twenty-six patients with 27 NSCLCs and four patients with five lung metastases underwent RF(More)
BACKGROUND Inflammation of the asthmatic airway is usually accompanied by increased vascular permeability and plasma exudation. Cysteinyl leukotrienes (cysLTs) potently elicit increased vascular permeability in airways, leading to airway edema. Vascular endothelial growth factor (VEGF) is 1 of the most potent proangiogenic cytokines and also increases(More)
PURPOSE High resolution magnetic resonance imaging (HRMRI) has been used as an imaging modality to depict the intracranial artery wall. The aim of this study was to compare images of the vessel wall between symptomatic and asymptomatic atherosclerotic plaques of the middle cerebral artery (MCA) using HRMRI. MATERIALS AND METHODS From September 2009 to(More)
OBJECTIVE We sought to describe the appearance of primary and secondary lung malignancies treated with radiofrequency ablation on follow-up helical CT and to identify the important CT findings for evaluating therapeutic efficacy and response on follow-up CT. MATERIALS AND METHODS Among the 21 patients in our study population, 17 had lung cancer and four(More)
Clear cell tumor of the lung is a rare and very unusual benign pulmonary tumor. As clear cell tumor of the lung contains abundant cytoplasmic glycogen, this tumor is called "sugar tumor". We report a case of sugar tumor in a 64-yr-old man presenting as a round pulmonary nodule. On dynamic computed tomography (CT) scans, the solitary pulmonary nodule showed(More)
Primary inflammatory myofibroblastic tumors (IMTs) of the breast are uncommon and metastasis of IMTs is extremely rare. To date, the natural course of this disease is not fully understood. Although patients with IMTs should undergo regular follow-up after complete surgical resection of the tumor, the appropriate interval and method of follow-up are unclear.(More)
We retrospectively compared the survival rate in patients with non-small-cell lung cancer (NSCLC) treated with radiofrequency ablation (RFA), surgery, or chemotherapy according to lung cancer staging. From 2000 to 2004, 77 NSCLC patients, all of whom had WHO performance status 0–2 and were >60 years old, were enrolled in a cancer registry and(More)
PURPOSE To determine the prevalence of interstitial lung abnormalities (ILAs) at initial computed tomography (CT) examination and the rate of progression of ILAs on 2-year follow-up CT images in a National Lung Screening Trial population studied at a single site. MATERIALS AND METHODS The study was approved by the institutional review board and informed(More)
We aimed to estimate the prevalence of combined pulmonary fibrosis and emphysema (CPFE) and describe the follow-up CT results of CPFE in asymptomatic smokers. This study was retrospective, and approved by an institutional review board. CT images of 2,016 current or previous male smokers who underwent low-dose chest CT at our healthcare centre were reviewed.(More)
RATIONALE Vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) are mediators of airway inflammation and remodeling in asthma. OBJECTIVES This study investigates a potential relationship between VEGF and MMP-9, and the mechanisms by which VEGF signaling regulates MMP-9 expression in asthma. METHODS We evaluated whether levels(More)
