| 1 | Coronary artery calcium score on low-dose computed tomography for lung cancer screening显示文摘AIM: To evaluate the feasibility of coronary artery calcium score(CACS) on low-dose non-gated chest CT(ngCCT).METHODS: Sixty consecutive individuals(30 males; 73 ± 7 years) scheduled for risk stratification by means of unenhanced ECG-triggered cardiac computed to-mography(gCCT) underwent additional unenhanced ngCCT. All CT scans were performed on a 64-slice CT scanner(Somatom Sensation 64 Cardiac, Siemens, Germany). CACS was calculated using conventional methods/scores(Volume, Mass, Agatston) as previ-ously described in literature. The CACS value obtained were compared. The Mayo Clinic classification was used to stratify cardiovascular risk based on Agatston CACS. Differences and correlations between the two methods were compared. A P-value < 0.05 was considered sig-nificant.RESULTS: Mean CACS values were significantly higher for gCCT as compared to ngCCT(Volume: 418 ± 747 vs 332 ± 597; Mass: 89 ± 151 vs 78 ± 141; Agatston: 481 ± 854 vs 428 ± 776; P < 0.05). The correlation between the two values was always very high(Volume: r = 0.95; Mass: r = 0.97; Agatston: r = 0.98). Of the 6 patients with 0 Agatston score on gCCT, 2(33%) showed an Agatston score > 0 in the ngCCT. Of the 3 patients with 1-10 Agatston score on gCCT, 1(33%) showed an Agatston score of 0 in the ngCCT. Overall, 23(38%) patients were reclassified in a different car-diovascular risk category, mostly(18/23; 78%) shifting to a lower risk in the ngCCT. The estimated radiation dose was significantly higher for gCCT(DLP 115.8 ± 50.7 vs 83.8 ± 16.3; Effective dose 1.6 ± 0.7 mSv vs 1.2 ± 0.2 mSv; P < 0.01).CONCLUSION: CACS assessment is feasible on ngCCT; the variability of CACS values and the associated re-stratification of patients in cardiovascular risk groups should be taken into account. | Teresa Arcadi Erica Maffei Nicola Sverzellati Cesare Mantini Andrea I Guaricci Carlo Tedeschi Chiara Martini Ludovico La Grutta Filippo Cademartiri | 2014 | World Journal of Radiology2014，6，6： | 4 |
| 2 | Mortarless structures based on topological interlocking显示文摘We review the principle of topological interlocking and analyze the properties of the mortarless structures whose design is based on this principle.We concentrate on structures built of osteomorphic blocks-the blocks possessing specially engineered contact surfaces allowing assembling various 2D and 3D structures.These structures are easy to build and can be made demountable.They are flexible,resistant to macroscopic fractures and tolerant to missing blocks.The blocks are kept in place without keys or connectors that are the weakest elements of the conventional interlocking structures.The overall structural integrity of these structures depends on the force imposed by peripheral constraint.The peripheral constraint can be provided in various ways:by an external flame or features of site topography,intemal prestressed cables/tendons,or self-weight and is a necessary auxiliary element of the structure.The constraining force also determines the degree of delamination developing between the blocks due to bending and thus controls the overall flexibility of the structure thus becoming a new design parameter. | Arcady V.DYSKIN Elena PASTERNAK Yuri ESTRIN | 2012 | Frontiers of Structural and Civil Engineering2012，6，2： | 4 |
| 3 | 有 CT 冠的 angiography 的匾成像: 匾类型分类上的 intra 脉管的变细的效果显示文摘 AIM:To assess the attenuation of non-calcified atherosclerotic coronary artery plaques with computed tomography coronary angiography(CTCA).METHODS:Four hundred consecutive patients underwent CTCA(Group 1:200 patients,Sensation 64 Cardiac,Siemens;Group 2:200 patients,VCT GE Healthcare,with either Iomeprol 400 or Iodixanol 320,respectively) for suspected coronary artery disease(CAD).CTCA was performed using standard protocols.Image quality(score 0-3),plaque(within the accessible non-calcified component of each non-calcified/mixed plaque) and coronary lumen attenuation were measured.Data were compared on a per-segment/perplaque basis.Plaques were classified as fibrous vs lipid rich based on different attenuation thresholds.A P < 0.05 was considered significant.RESULTS:In 468 atherosclerotic plaques in Group 1 and 644 in Group 2,average image quality was 2.96 ± 0.19 in Group 1 and 2.93 ± 0.25 in Group 2(P ≥ 0.05).Coronary lumen attenuation was 367 ± 85 Hounsfield units(HU) in Group 1 and 327 ± 73 HU in Group 2(P < 0.05);non-calcified plaque attenuation was 48 ± 23 HU in Group 1 and 39 ± 21 HU in Group 2(P < 0.05).Overall signal to noise ratio was 15.6 ± 4.7 in Group 1 and 21.2 ± 7.7 in Group 2(P < 0.01).CONCLUSION:Higher intra-vascular attenuation modifies significantly the attenuation of non-calcified coronary plaques.This results in a more difficult characterization between lipid rich vs fibrous type. | Erica Maffei Chiara Martini Teresa Arcadi Alberto Clemente Sara Seitun Alessandra Zuccarelli Tito Torri Nico R Mollet Alexia Rossi Onofrio Catalano Giancarlo Messalli Filippo Cademartiri | 2012 | World Journal of Radiology2012，4，6： | 3 |
