| 中文摘要: |
| 目的通过26例超急性期脑卒中病例,观察和分析脑梗塞与脑出血的MR表现及诊断要点。方法26例在低场强机器作常规横断SE序列T1WI和T2WI扫描。结果脑梗塞为T1WI稍低信号、T2WI高信号；脑出血为T1WI稍高至更高信号,T2WI高至等偏高信号,周围有T1WI低、T2WI高信号水肿带。结论超急性期脑梗塞与脑出血各具不同的信号形式,能较好鉴别,可选择性使用MRI进行检查。 |

| Purpose To observe the MR representations of brain hemorrhage and brain occlusion,and to analysis the key points of diagnosis on 26 cases of ultracute apoplexy.Methods 26 cases were scanned by traditional crossing SE sequence T1WI and T2WI by low-magnetic-field machine.Results If the patients had brain hemorrhage,the signal was a slightly low T1WI and high T2WI;if brain occlusion,the signal was a slightly high or even higher T1WI,high to equally high T2WI wit around edema area of low T1WI、high T2WI.Conclusion The signal representations were different between alteractes brain hemorrhage and brain occlusion recognition could be well made.MRI was a selective examining method. |
