现代癌症的临床治疗需要精确的位置信息。比如肿瘤的位置、大小,是否受限或已扩散到淋巴结中,是否包含一些可改变治疗策略的关键解剖学结构。随着空间分辨率不断增加,传统的解剖影像学方法在逐步解决此类问题,如计算机X射线断层造影术(CT),核磁共振影像学(MRI)和超声(US)方法。 Clinical treatment of modern cancer requires precise location information. Such as the location, size, limited or spread of the tumor to the lymph nodes, and whether there are key anatomical structures that alter the treatment strategy. As spatial resolution continues to increase, traditional anatomical imaging methods such as computed tomography (CT), magnetic resonance imaging (MRI) and sonography (US) have been gradually addressed.
