本文分析了我院103例行CT检查,经手术病理证实的脑膜瘤。男36例,女67例。发病年龄7～71岁。其中31～50岁的发病率最高,占61.9%。手术结果CT定位诊断正确率达100%,定性诊断为90.3%。脑膜瘤的CT表现有典型表现及非典型表现。本组95例(92.2%)有典型表现。其特点有如下几点:1.增强前CT图像多表现为高密度(CT值>40H),其次为等密度(30～40H),个别为低密度或混合密度。增强后均表现为均匀一致的明显增高。增强质为3.6～72H不等。以等密度脑膜瘤增强最明显。密度越高增强越 This article analyzes 103 cases of our hospital CT examination, confirmed by surgical pathology meningioma. 36 males and 67 females. Age 7 to 71 years of age. The highest incidence of 31 to 50 years old, accounting for 61.9%. Surgical results of CT diagnosis of the correct rate of 100%, a qualitative diagnosis of 90.3%. The manifestations of meningioma with CT manifestations and atypical manifestations. The group of 95 patients (92.2%) have a typical performance. The features are as follows: 1. Enhanced CT images before the performance of high-density (CT value> 40H), followed by the same density (30 ~ 40H), each for the low-density or mixed density. After the enhancement showed a significant increase in uniform. Enhance the quality of 3.6 ~ 72H range. Islet density increased meningioma the most obvious. The higher the density, the stronger the enhancement
