【摘要】 分析闭合性脑外伤脑灌注改变与临床预后的关系，评价闭合性脑外伤的预后。方法：应用连续快速断层（Con－SPECT）方法，对27例轻中度闭合性脑外伤在入院时和受伤3月后分别进行脑灌注显像，观察患者脑灌注改变。结果：研究表明脑灌注显像对脑外伤患者病灶检测的阳性率明显高于CT，P＜0．05；入院首次脑显像阳性患者脑外伤综合征发病率显著高于显像阴性患者，P＜0．05，而且复查显像病灶无明显好转。患者脑外伤综合征发病率为78％，明显高于复查结果病灶明显吸收的患者，P＜0．05。结论：Con-SPECT脑灌注显像方法简单方便，脑灌注显像对轻中度脑外伤预后的预测及评价有重要价值。更多还原

【Abstract】 Objective: To study the predictive evaluation of patients with closed brain theuma. Methods: 27 patients sustainedmild or moderate closed cranial trauma were examined with continuous quick SPECT CBF imag (Con - SPECT)at eary of entrance and later after three months. Results: Con - SPECT CBF image is a convenient method exedned the peients with the brain trauma. The positiverate of SPECT is higher than CT scans, P < 0. 05, the patients with head posthaumatic syndrome when there was a positive result of firstSPECT examination is more than ones when there was a negative, P < 0.05.The occur rate of head posttheumatic syndrome of patients is78% whose btaln disease focus was not significantly recovewhle hy the repeated SPECT examination, and is higher than that of whose focuswas notable improvement, P < 0. 05. Conclusions: Con - SPECT CBF image is a convenient method of evaluation the pwhictive value of patients with mild or moderate brain trauma.更多还原
