| 1 | Feasibility and accuracy of coronary imaging in elderly patients using the 64-row multi-detector computed tomography: a correlation study with conventional coronary angiography显示文摘Background Elderly patients generally have higher occurrence of coronary calcification, increased heart rate and difficulty with prolonged breath-holding. The aim of our study was to investigate the feasibility and accuracy of using 64-row multi-detector computed tomography (MDCT) in the assessment of coronary artery stenoses in elderly patients. Methods One hundred and fifty two patients with suspected or known coronary artery disease were divided into 4 groups according to their age (Group A: 40-49 years,n=34; Group B: 50-59 years, n=57; Group C: 60-69 years, n=48; Group D: 70 years and above; n=13). Coronary CT angiography (CTA) using a 64-row MDCT was performed and the findings were compared with that of conventional coronary angiography (CCA).Using axial images, multi-planar reconstructions (MPR) and maximum intensity projections (MIP), coronary segments of lumen diameter = 1.5mm were analyzed for the presence of significant stenosis (= 50% ). Results Percentages of poor image quality from coronary CTA preventing reliable correlations with CCA were 21%, 14%, 19% and 62% in Groups A to D respectively. Patients in Group D had significantly higher calcium scores compared with the other groups (P<0.001). In patients where CTA images were of acceptable quality, percentages of accurate correlations with CCA were 89.8%, 93.4%, 86.6% and 78.0% for Groups A to D respectively.There were no significant difference in serum creatinine, heart rate and contrast volume between the 4 groups. Conclusions The 64-row MDCT coronary angiography was less accurate and feasible for patients aged 70 years or above due to heavy coronary calcification and inability to perform a satisfactory breath-hold. However, a high diagnostic accuracy with the MDCT is possible in patients aged less than 70 years. | Chee Khoon LIEW Sze Piaw CHIN Tiong Kiam ONG Seyfarth Tobias Yean Yip FONG Choon Kiat ANG Houng Bang LIEW Rapaee ANNUAR Kui Hian SIM | 2006 | Journal of Geriatric Cardiology2006，3，1： | 4 |

| 15 | The stellar system HIP 101227:is it a binary,a triple or a quadruple system?显示文摘In this paper,we present the analysis of the stellar system HIP 101227 to determine the actual number of components in the system,and their properties.We use dynamical modeling and complex spectrophotometric(involving atmospheric modeling)techniques with recent data,to determine the physical properties and orbital solution for the system,respectively,with better accuracy than past studies.Based on our analysis,we found that the system is more consistent with being a quadruple rather than a binary or a triple system as suggested by previous studies.The total mass of the system determined from our SED analysis is 3.42±0.20 M,which is distributed almost equally between the four stars.The stars are found to be zero-age main sequence stars;i.e.,at the last stage of pre-main sequence,with age less than 200 Myr and spectral types K0.All four stars have very similar physical characteristics,suggesting that the fragmentation process is the most likely theory for the formation and evolution of the system. | Zahra Talal Yousef Adlyka Annuar Abdallah Mohammad Hussein Hamid Al-Naimiy MashhoorAl-Wardat Nurul Shazana Abdul Hamid Mohammed Fadil Talafha | 2021 | Research in Astronomy and Astrophysics2021，21，5： | 1 |
