| 2 | 全身弥散加权成像在骨转移瘤的临床应用探讨(英文)显示文摘Objective: We evaluated (Whole-Body Diffusion Weighted Imaging, WB-DWI) application in bone metastasis. Methods: WB-DWI with GE 1.5T MR/I was performed on 10 healthy volunteers and 35 patients. WB-DWI and ECT was performed in all 35 patients. Using WB-DWI for detecting bone metastasis and compared them with that of ECT. Results: Background was suppressed in WB-DWI, fat, muscle, vessels and liver appeared same as background. Skeleton showed medium or slightly lower signal. Lymph nodes, some glandular organs, kidneys displayed medium signal. Spleen, testicle, brain tissue were low signal. Bladder, gallbladder were depicted as low signal because of 'T2 through'. Bone metastasis were multitude and inequality of size, punctiform, nodosity, column low intensity. Concordance between WB-DWI and ECT was seen in 4 cases. WB-DWI displayed 1 bone metastasis on skull, 46 on rib and sternum, 3 on scapula, 4 on extremities, 83 on vertebral, 36 on pelvic bone. ECT showed 2 bone metastasis on skull, 62 on rib and sternum, 7 on scapula, 9 on extremities, 64 on vertebral, 19 on pelvic bone. WB-DWI was 74% for bone metastasis on rib and sternum, ECT was 77%, 53% for vertebral and pelvic bone. All of the focus were statistics analyses, P < 0.05. Total probability distribution inequality if metastasis on different positions. Conclusion: WB-DWI was an effective imaging technology for screening bone metastasis. | Xv Wu Changying Ma Xia Zhao Shaowu Wang | 2010 | The Chinese-German Journal of Clinical Oncology2010，9，1： | 1 |
| 5 | Research of social desirability responding effect on 16PF in mental test context显示文摘AIM: To examine whether the social desirability response has an effect on the structure validity of 16 PF. After controlling for the effect of social desirability,it can improve the predictive validity of 16 PF and accuracy of different selection decision. METHODS: A total of 1224 subjects were tested for two times and the interval was 7 months. The 16 PF and the 'Social Desirability Scale in Context of Psychological Screening',were used to verify and clarify the social desirability response to the structure of 16 PF and its impact on the secondary factor structure theory model. RESULTS: The social desirability response had a significant effect on the 16 PF root traits,structure validity and the theoretical model of the secondary factors,but the influence was small and the influence was not significant. CONCLUSION:The structure validity of the 16 PF is not significantly affected by the test motivation or social desirability,and the social desirability response in the psychological test of the military academy students will not have a significant impact on the structure validity of the personality test. | WANG You-Lin MA Ru-Meng DAI Jing LI Xiao-Jing ZHANG Li-Li HUI Duo-Duo MA Jin HU Wen-dong XV Bo | 2016 | 转化医学电子杂志2016，3，1： | 0 |
