MRI和CT对急性脑梗塞早期临床诊断价值对比

MRI和CT对急性脑梗塞早期刖临床诊断价值对比摘要目的：本文将对磁共振成像(MR)和电子计算机断层扫描(CT)在检查早期急性脑梗塞疾病的临床诊断价值进行对比分析。帮助早期急性脑梗塞患者选择能够高效精准检查出结果的检查技术，提供确切数据以供治疗。方法：回顾性选取2020-2023年就诊于保定市第一中心医院的早期急性脑梗塞患者90例，年龄在42-83岁之间，经过患者及其家属同意后，所有患者都进行了MRI与顿脑CT检查，比较分析MRI和颅脑CT对于12h以内、12-24h以及超过24h三个不同发病时间患者的检出结果、检出部位的不同、检出病灶大小、影像表现等检出结果。结果：MRI检查在不同时间段的检出数量多于顿脑CT,位于颅脑不同部位的检出病灶数量MRI检查多于顿脑CT,MRI检查检出的病灶大小小于颅脑CT。结论：磁共振成像MR)相比电子计算机断层扫描(CT)来说，在早期急性脑梗塞的诊断方面具有更突出的临床效果。关键词：磁共振成像MR):电子计算机断层扫描(CT检查：急性脑梗塞早期ABSTRACTObjective:This paper will compare the clinical diagnostic value of magnetic resonanceimaging (MRI)and computed tomography (CT)in detecting early acute cerebral infarction.Tohelp patients with early acute cerebral infarction choose the examination technology that candetect the results efficiently and accurately,and provide accurate data for treatment.How:A totalof 90 patients with early acute cerebral infarction (aged 42-83 years)admitted to the First CentralHospital of Baoding City from 2020 to 2023 were retrospectively selected.With the consent ofthe patients and their families,MRI and cranial CT examinations were performed on all patients.The detection results of MRI and brain CT in patients with three different onset times within 12h,12-24h and more than 24h were compared and analyzed,as well as the different detection sites,the detected lesion size and image manifestations.Results:The number of lesions detected byMRI in different time periods was more than that by brain CT,the number of lesions detected byMRI in different parts of brain was more than that by brain CT,and the size of lesions detectedby MRI was less than that by brain CT.Conclusion:Compared with computed tomography (CT),magnetic resonance imaging (MRI)is more effective in the early diagnosis of acute cerebralinfarction.Key words:Magnetic resonance imaging (MRI);Computed tomography (CT)examination;Early acute cerebral infarction目录第1章3言.1第2章资料与方法22.1一般资料.。22.2方法22.2观察指标与评价标准…3第3章结果43.1MRI检查与颅脑CT脑梗塞检出率及不同时间段检出率的对比.43.2MRI检查与颅脑CT在颅脑不同部位检出率的对比..43.3MRI检查与颅脑CT对于检出病灶大小的对比.53.4MRI检查与顿脑CT检查影像表现的对比..6第4章讨论.7结论10参考文献致谢，.12第1章引言急性脑梗塞，又称脑梗死或中风，是一种常见的神经系统急症，指脑血管突然堵塞，造成大脑供血供氧不足。脑梗塞的发病机制通常与血管内的血栓形成或者远处血栓脱落后随血流至脑血管引起的栓塞有关。该病具有发病人数多、致残、致死人数多、极易复发和高额花费的特点，已经和心血管疾病一起成为危害我国民众第一位的死亡原因。在西欧、美国等发达国家和地区，每年脑卒中的发病率为每十万人中超过150个人：中国脑梗塞发病率不低反高，某些地区的年患病率达到每十万人中超过300至400个人山。该病为老年人群中比较常见的疾病，近年来有逐渐年轻化趋势，临床征象表现为突然出现言语含糊不清、多发流口水、感觉意识障碍，甚至出现偏瘫、痴呆、昏迷等症状，严重患病者可能偏瘫、痴呆甚至昏迷，生活不能自理，对患者家庭的生活及经济产生严重影响。对于早期急性脑梗塞来说，早期及时诊断、准确定位、改善局部血供环境对治愈患者意义非凡。患者就医后，主要进行的是影像学检查，而MI与CT作为当前临床常用的影像检查技术，本文基于此，对二者诊断急性脑梗塞早期的诊断价值进行比较研究。
