The analysis based on the household survey in 2013 shows that the targeting accuracy is not high based on the standard of income and the accuracy is higher based on the standard of multidimensional poverty index. But the latter still has a low coverage rate. To gradually achieve integration of the rural poverty line and the rural subsistence allowance line, standards applied to identifying households entitled to subsistence allowances should be changed from the standard of income to multidimensional poverty indexes. A unified standard of subsistence allowances and a unified method for identifying related households should be developed. At the same time, coverage and funding of subsistence allowances should be extended and increased to better meet people's basic needs.展开更多
目的:探讨多模式MR检查对急性脑卒中患者的应用价值。方法:选取临床拟诊为急性脑卒中的194例患者的CT和多模式MR影像,对比CT和多模式MR对急性脑梗死、陈旧性脑出血、急性脑出血、蛛网膜下腔出血、动脉瘤、动静脉畸形、脑微出血的检出率...目的:探讨多模式MR检查对急性脑卒中患者的应用价值。方法:选取临床拟诊为急性脑卒中的194例患者的CT和多模式MR影像,对比CT和多模式MR对急性脑梗死、陈旧性脑出血、急性脑出血、蛛网膜下腔出血、动脉瘤、动静脉畸形、脑微出血的检出率。结果:194例患者,CT与多模式MR对急性脑梗死、陈旧性脑出血、急性脑出血、蛛网膜下腔出血、动脉瘤、动静脉畸形、脑微出血的检出率分别为(26.8%VS 54.1%、5.7%VS 5.7%、27.3%VS 27.3%、7.7%VS 7.7%、0 VS 9.8%、0 VS 1.0%、0 VS 22.7%),CT不能显示脑微出血。T2WI与DWI对急性脑梗死的检出率分别为29.4%VS 54.1%,差异有统计学意义(P<0.05)。T2~*梯度回波序列(T2~*GRE)检出44例脑微出血,常规MR未能检出。结论:对于急性脑卒中患者,多模式MR检查可在短时间内为临床提供较全面的影像信息制定治疗方案。展开更多
