OBJECTIVE To analyze the computed tomography (CT) findings of fatty replacement in the right ventricle (RV) of asymptomatic subjects and to correlate the CT findings with electrocardiogram (ECG) abnormalities. METHODS This prospective study included 996 subjects who underwent ECG-gated 16-slice CT for determination of coronary calcium scores. The CT(More)
The aim of this study was to compare the radiation dose and image quality of different adenosine-stress dynamic myocardial perfusion CT protocols using a 128-slice dual-source computed tomography (DSCT) scanner. We included 330 consecutive patients with suspected coronary artery disease. Protocols employed the following dynamic scan parameters: protocol I,(More)
OBJECTIVES This study aimed to assess the diagnostic performance of adenosine-stress dual-energy myocardial computed tomography perfusion (DECTP) imaging using 128-slice dual-source computed tomography (CT) for the detection of myocardial perfusion defects in comparison with stress-perfusion magnetic resonance imaging (MRI). METHODS This prospective study(More)
OBJECTIVE The purpose of this study was to evaluate the performance of an automated computer-assisted detection (CAD) algorithm to detect coronary artery stenosis on coronary CT angiography (CTA). MATERIALS AND METHODS We investigated 128 consecutive patients (76 men, 52 women; mean [SD] age, 64 ± 11 years) who had acute chest pain and underwent 128-slice(More)
OBJECTIVE The purpose of our study was to show the usefulness of nongated low-dose chest CT for coronary screening by comparing the results of coronary artery calcium measurement with that of dedicated calcium-scoring CT. MATERIALS AND METHODS One hundred twenty-eight consecutive participants (all men; mean age, 52 +/- 7 years) underwent low-dose chest CT(More)
Natural Killer cells are known to play a major role in the innate immune response against viral infections and tumor cells. Several viruses, such as CMV, EBV and HIV-1, have acquired strategies to escape elimination by NK cells. In this study, we observed that EBV infection increased expression of IDO on B cells. To evaluate the function of IDO associated(More)
The aim of this study was to determine the normal values for aortic pulse wave velocity (PWV) and distensibility using cine and phase contrast cardiac magnetic resonance imaging (CMRI) in patients without cardiovascular risk factors. PWV and distensibility are indispensible predictors of global and regional cardiovascular risk. Regional heterogeneity in(More)
A Gram-positive, slightly acid-alcohol-fast, carbon monoxide-oxidizing bacterium, strain Y2(T), was isolated from a soil sample collected from a roadside in Seoul, Korea. On the basis of 16S rRNA gene sequence comparative analyses, strain Y2(T) was shown to belong to the genus Tsukamurella and was most closely related to Tsukamurella tyrosinosolvens DSM(More)
BACKGROUND Coronary collateral flow is an alternative source of myocardial perfusion in patients with totally occluded coronary arteries. Clinical evaluation of collateral flow has been limited by the need of invasive measurements. We investigated whether noninvasive coronary computed tomographic angiography can evaluate the angiographic extent of coronary(More)
OBJECTIVES This study investigated the role of fractional myocardial mass (FMM), a vessel-specific myocardial mass, in the evaluation of physiological severity of stenosis. Using computed tomography angiography, the study investigated fractional myocardial mass, a concept of myocardial mass subtended by specific vessel, which could reduce(More)
