本文报道291例缺血性脑梗塞的老年患者,在超低场磁共振成像(ULF-MRI)上脑室测量的方法和结果。结果显示:脑室指数(D/A),侧脑室体部宽度指数(G/E)和前角指数(G/A),在男性随年龄增加而渐减。D/A和G/E,<60岁和≥60岁年龄组间差异有显著意义(P<0.05)。用脑室3项指数判断脑萎缩之有无及其程度,与测量前常规读片综合观察判断基本吻合。MRI上脑室测量较为客观,可供评估脑萎缩的参考。 This paper reports the results of 29 ventricular measurements on ULF-MRI in 291 elderly patients with ischemic cerebral infarction. The results showed that the ventricular index (D / A), lateral ventricular body width index (G / E) and anterior horn index (G / A) decreased with the increase of age in males. There was significant difference between D / A and G / E, <60 years old and ≥60 years old group (P <0.05). Using the three indexes of cerebral ventricle to judge whether brain atrophy exists and its extent, which is consistent with the general observation and judgment of routine reading before measurement. MRI upper ventricle measurement is more objective, available for assessing brain atrophy reference.
