STUDY OBJECTIVE To evaluate the feasibility of lung cancer screening using low-dose spiral CT as a part of annual health examinations. DESIGN Nonrandomized, screening practice. METHODS From April 1998 to August 2000, CT screening was performed as a part of annual health examinations on a total of 7,956 individuals who belonged to the Hitachi Employee's(More)
OBJECTIVE Although abdominal obesity and related metabolic abnormalities are hypothesized to promote colorectal carcinogenesis, direct confirmation of this effect is required. Here, we examined the relation of early-stage colorectal neoplasia to visceral fat area and markers of insulin resistance. RESEARCH DESIGN AND METHODS Subjects were participants in(More)
Recent US clinical trial demonstrated that CT screening prevents lung cancer death among high risk individuals. However, it remains unclear whether wide implementation of low-dose CT screening for lung cancer can decrease mortality in the community. Among residents in Hitachi City (Japan), where nearly 40% of inhabitants aged 50-69 years were estimated to(More)
Solitary extramedullary plasmacytomas are uncommon malignant neoplasms accounting for 5-10% of all plasma cell malignancies." 2 The majority of extramedullary plasmacytomas are seen in head and neck region and frequently arise from the upper aerodigestive tract.3 Solitary plasmacytoma of the tongue is extremely rare, with only a few cases having been(More)
The effectiveness of lung cancer screening using low-dose chest computed tomography (CT) remains elusive. The present study examined the prognosis of patients with lung cancer detected on CT screening in Japanese men and women. Subjects were 210 patients with primary lung cancer identified on CT screening at two medical facilities in Hitachi, Japan, where a(More)
We assessed the prevalence of emphysematous changes among healthy workers and retired persons, using subjective evaluations of low-dose spiral CT images obtained during thoracic CT screenings for lung cancer. Among 6144 male participants (50-69 years old; mean age, 57), we detected 686 cases (11.2%) with emphysematous changes. The majority (95.3%) of(More)

Contrast-enhanced magnetic resonance images (MRI) of three patients with subdural (SDE) and two with epidural empyemas (EDE) were reviewed. In each case, the capsule of the lesion demonstrated enhancement, and distinction between capsule and contents was obvious on contrast-enhanced images. In SDE, contrast-enhanced images clearly depicted thickening of the(More)
PURPOSE The aim of this study was to evaluate the efficacy of a computer-aided diagnosis (CAD) system we developed that can also respond to subsolid nodules, for lung cancer screening using low-dose spiral computed tomography (LDCT). MATERIALS AND METHODS The institutional review board approved this study. A total of 30 positive cases (including 15 lung(More)
