TC-pertechnetate脑闪烁照相(TC~(99)-scan)曾广泛应用于订局灶神经缺损的患者,其中大部分是卒中患者.Dudley等(1970)和Anderson等(1980)均认为TC~(99)-Scan的结果取决于损害处的血管通透性.损伤组织经过早期的缺血直至最后疤痕组织形成,血管通透性是构成这些变化的一个部分,也就是说Tc~(99)-scan的结果与梗塞的期限有很大关系.本文主要研究脑血管疾病患者的损害大小、类型、部位及期限对TC~(99)-scan结果的影响,并与CT-scan作比较.本组95例脑血管损害患者(TIA、脑梗塞及脑内血肿),年龄在75岁以下,均于症状开始后3天内入院.TC~(99)-scan在患者入院后1周(平均5天)、2周(平均8天)、3月(平均103天)、6月(平均194天)共进行4次;CT-scan在入院后2天(平均3天)、2周(平均18天)、6月(平均207天)共进
TC-pertechnetate brain scintigraphy (TC ~ (99) -scan) has been widely used in patients with focal neurological deficits, most of whom are stroke patients .Dudley et al. (1970) and Anderson et al. (1980) 99) The result of -Scan depends on the vascular permeability at the lesion. The damaged tissue undergoes early ischemia until the formation of the last scar tissue, and the vascular permeability constitutes a part of these changes, that is, Tc99- scan results and the duration of the infarction has a great relationship.This paper mainly studies the impact of cerebrovascular disease damage size, type, location and duration of TC ~ (99) -scan results, and compared with CT-scan.This group Ninety-five patients with cerebrovascular injury (TIA, cerebral infarction and intracerebral hematoma), aged below 75 years of age, were all admitted within 3 days after symptom onset.TC- (99) -scan was given 1 week after admission to patients (mean, 5 days) , 2 weeks (average 8 days), 3 months (average 103 days) and June (average 194 days). CT-scan was performed 2 days after admission (average 3 days) and 2 weeks , June (an average of 207 days) together
