本文报道以~(99m)Tc-ECD作为显像刹,SPECT脑断层显像检查148例,包括脑动脉硬化77例,脑梗塞25例,血管性头痛20侧,TIA7侧,癫痫6例,脑出血5例,脑肿瘤4例,其它4例,总阳性率7O.3%(104/148)。32例同时做CT检查,结果SPECT阳性率高。脑动脉硬化多表现为多发病灶,血管性头痛病变部位各叶之间无明显差别。结果认为~(99m)Tc—ECD脑血流灌注断层显像对各种脑部疾患的诊断具有重要临床意义。 This paper reports the ~ (99m) Tc-ECD as imaging brake, SPECT brain imaging 148 cases, including 77 cases of cerebral arteriosclerosis, cerebral infarction in 25 cases, vascular headache 20 side, TIA7 side, epilepsy in 6 cases, brain Bleeding in 5 cases, brain tumors in 4 cases, the other 4 cases, the total positive rate was 70.3% (104/148). 32 cases at the same time to do CT examination, the results of SPECT positive rate. More manifestations of cerebral arteriosclerosis multiple lesions, vascular headache lesions no significant difference between the leaves. The results show ~ (99m) Tc-ECD cerebral perfusion tomography for the diagnosis of various brain disorders has important clinical significance.
