本文分析118例颅内占位性病变的脑扫描,总阳性率 71.2％。按病理性质则脑膜瘤、转移瘤、颅内血肿及脑脓肿的阳性率最高,均为100％;与其它诊断方法相比,本组脑扫描除大脑半球病变外,阳性率低于脑血管、气脑、脑室造影等,但因它为无创伤性,而其它方法多在脑扫描筛选后有选择地进行,故此法仍不失为颅内病变首选的诊断方法。 This article analyzes 118 cases of intracranial space-occupying lesions of the brain scan, the total positive rate of 71.2%. According to pathological features, the positive rate of meningiomas, metastases, intracranial hematomas and brain abscesses was the highest, both of which were 100%. Compared with other diagnostic methods, the positive rate of cerebral hemorrhage in this group was lower than that of cerebral blood vessels, But it is non-invasive, and other methods are more selective after brain scan screening, so this method is still the preferred method of diagnosis of intracranial lesions.
