近年来,随着影像学技术的不断发展,越来越多的放射诊疗技术和设备被应用到临床诊疗过程中。如CT、磁共振成像(MRI)、正电子发射型计算机断层显像(PET)、单光子发射计算机断层成像术(SPECT)及介入诊疗等,这些检查的物理基础、成像原理、不同病变的影像改变各不相同,怎样选择适合相应症状的影像检查方法,减少不必要的X线辐射,减轻患者医疗负担,结合本人多年从事影像诊断的工作经验,介绍如下。1根据临床症状选择检查方法
In recent years, with the continuous development of imaging technology, more and more radiotherapy techniques and equipment have been applied to the clinical diagnosis and treatment process. Such as CT, magnetic resonance imaging (MRI), positron emission tomography (PET), single photon emission computed tomography (SPECT) and interventional diagnosis and treatment, the physical basis of these tests, imaging principles, different lesion images Change the different, how to choose the appropriate imaging method for the corresponding symptoms, reduce unnecessary X-ray radiation, reduce the medical burden on patients, combined with my many years engaged in imaging diagnosis of work experience, described below. 1 according to the clinical symptoms to choose the inspection method
