摘要
灌注电子计算机X线体层显像(CT)是近年来由于多层螺旋CT的临床应用及灌注软件的开发应用而兴起的一种新的医学影像技术,最初灌注CT应用于肾脏及心肌,近年来广泛应用于全身多个器官。特别是在颅脑方面,灌注CT诊断早期脑梗死、脑肿瘤以及脑外伤等方面具有较高的准确性及特异性,并且实现了CT诊断从单纯的诊断结构异常到诊断功能状态的飞越,灌注CT势必拥有一个广阔的发展前景。
Peffusion computed tomography （PCT） is a new rising techniques in medical imaging with the clinical application of multi-slice computed tomography （MSCT） and development of its perfusion software. Although. PCT was applyed to kidney and cardiac muscle at first,it has been applied to many organs of the whole body in recent years, especially in brain. PCT has higher accuracy and specificity in diagnosing early brain infarction,brain tumor,brain trauma and so on,and achieved the overfly from single diagnosis of structural abnormality to ftmctional diagnosis. PCT will have a wide future.
