OBJECTIVE To determine whether the subtypes of nonspecific interstitial pneumonia (NSIP) could be differentiated from other idiopathic interstitial pneumonias (IIPs) on the basis of findings on high-resolution computed tomography (CT). METHODS Two observers evaluated the high-resolution CT findings in 90 patients with IIPs. The patients included 36 with(More)
PURPOSE To assess by means of cine magnetic resonance imaging (MRI) aortic compliance before and after aortic valve replacement (AVR with SJM valve) in patients with aortic regurgitation (AR). MATERIALS AND METHODS Two groups (healthy controls and patients with severe isolated AR) of 10 subjects each were included in this study. Cine MRI was performed at(More)
PURPOSE To compare observer performance in the detection of subtle interstitial abnormalities on 3,520 x 3,520 (4K) matrix and 1,760 x 1,760 (2K) matrix full-size digital storage phosphor (DSP) chest radiographs. MATERIALS AND METHODS Thirty-five 4K DSP chest radiographs with subtle interstitial abnormalities (n=27) or normal lungs (n=8) were processed(More)
OBJECTIVE To investigate long-term trends in dietary intakes of vitamins A, C and E in Japanese adults. DESIGN Time series by community-based nutrition survey. SETTING Two rural communities (Ikawa and Kyowa) between 1974 and 2001 in Japan. SUBJECTS A total of 3713 men and 3726 women aged 40-69 years. METHODS Dietary intake data were collected by the(More)
PURPOSE The purpose of this study was to assess the usefulness of color digital summation radiography (CDSR) for detection of nodules on chest radiographs by observers with different levels of experience. MATERIALS AND METHODS A total of 30 radiographs of chest phantoms with abnormalities and 30 normal ones were arranged at random. Set A was conventional(More)
PURPOSE The aim of this study was to evaluate the usefulness of novel color digital summation radiography (CDSR) for detecting solitary pulmonary nodules on chest radiographs by observers with different levels of experience. MATERIALS AND METHODS A total of 30 healthy controls and 30 patients with newly detected solitary pulmonary nodules were evaluated.(More)
OBJECTIVE The aim of this study was to evaluate the image quality of high-resolution CT (HRCT) reconstructed from volumetric data with 16-channel multidetector-row CT (MDCT). SUBJECTS AND METHODS Eleven autopsy lungs that were diagnosed histopathologically were scanned by 16-channel MDCT with the step-and-shoot scan mode and three helical scan modes. Each(More)
BACKGROUND Hypertension and/or antihypertensive medication reportedly induce dry mouth; however, an immediate relationship between salivary flow and hypertension has not been elucidated. OBJECTIVES The purpose of the present study was to examine the association of hypertension and antihypertensive medication with salivary flow rate and pH in older adults.(More)
This paper describes an integrated methodology that addresses the operation of 3D imaging and measurement for the diagnosis and surgical operation of breast cancer. The main system for breast CT imaging used a multi-slice CT scanner and 3D-workstation. The clinical sequence was performed in three phases with non-contrast and biphasic contrast-enhanced(More)
Although the shortened dental arch (SDA) concept has been known to all over the world, acceptance of the SDA concept as an oral health standard can be questionable from the patients' point of view, even if it is biologically reasonable. Furthermore, because the health insurance system covers removable partial dentures (RPDs) for all citizens in Japan, SDA(More)
