脑SPECT显像和CT扫描观察高压氧治疗脑外伤后综合征疗效

目的 对比研究脑外伤后综合征患者在高压氧（ＨＢＯ）治疗前后的脑ＳＰＥＣＴ和脑ＣＴ扫描结果，并对两者的临床及其优越性进行评价。方法 ２８８例脑外伤后综合征患者接受２－４个疗程的ＨＢＯ治疗，并在治疗前后用＾９９Ｔｃ＾ｍ－双半胱乙酯（ＥＣＤ）ＳＰＥＣＴ和ＣＴ进行疗效监测和对比分析。

Comparative study of cerebral blood perfusion SPECT imaging and CT scan in evaluation of the curative effect of hyperbaric oxygen in patients with post traumatic brain syndrome

Objective To comparatively study the results of cerebral SPECT and cerebral CT before and after hyperbaric oxygen (HBO) treatment in post traumatic brain syndrome Methods HBO was used to treat 288 patients with post traumatic brain syndrome for two courses, and made therapeutic surveillance and comparative analysis with 99 Tc m ECD SPECT, CT before and after treatment Results Before treatment, the positive rate of cerebral SPECT was 80 6%, but the positive rate of CT was only 10 2%; after treatment, 90% of SPECT became negative, and the clinical symptoms of the patients disappeared as SPECT became negative The results showed that HBO treatment could evidently improve rCBF, and showed that SPECT was superior to CT in surveillance of HBO treatment Conclusions 99 Tc m ECD SPECT could play an important role in the diagnosis of post traumatic brain syndrome and the therapeutic surveillance of HBO
