随着医学影像技术的发展,胆系疾病的影像学检查技术也在原有X 线造影基础上,不断补充与完善,已形成包括X 线造影、超声、CT、MRI 等完整的检查体系.如何评价这些检查方法的作用,价值与限度,加以合理应用,对胆系疾病患的诊断与治疗是至关重要的.该文主要在此方面扼要加以论述.并对螺旋CT 胆道造影三维成象(SCTC) 及MRCP 之新技术应用加以探讨.从比较影像学角度,SCTC 三维立体成象可多方位、多角度观察病变,达到准确、具体的术前定位,为外科手术及腹腔镜胆道手术提供可靠的客观依据,为以往任何胆系检查方法所不及.MRCP 为当今胆系影像诊断中的新技术,在对梗阻性黄疸的诊断体系中,它结合MRI,又综合了ERCP 与PTC 的优点,避免了其缺点,为一种较理想的诊断方法.“,”As the development of medical image technology, great progress has been made in the imageological examination technique based on preliminary X-ray contrast technique, and an integral examination system has been built up, including X-ray contrast. Ultrasound (us), Computed tomography (CT), Magnetic resonance image (MRI). It is very important for us to get the correct diagnosis and therapy of cholccystocholangiopathy by evaluating the valuce and limitation of the examination method and applying them in clinical practice. The author has demonstrated them in short, and discussed the applications of new techniques of spiral computed tomgraphy cholangiography (SCTC) and magnetic resonance cholangiopancreaticography (MRCP).Being the characteristics of multi-view and Multi-angle of SCTC, we can get the precise and concrete information on the locations of the lesion of cholecystocholangiopathy before operation, and provide the reliable and objective evidence by using SCTC, which is superior to all the image technology prior to it. MRCP, a new technique in modern imageology being made full use of the advantage of both endoscopic retrograde cholangiopancreaticography (ERCP) and percutaneous transhepatic cholangiography (PTC) as well as being avoided the deficit from ERCP and PTC, is an ideal method in the diagnosing of obstructive jaundice.
