Abstract

Nuclear medicine is a medical specialty that uses radioactive tracers (radiopharmaceuticals) to assess bodily functions and to diagnose and treat disease. Specially designed cameras allow doctors to track the path of these radioactive tracers. Single Photon Emission Computed Tomography or SPECT and Positron Emission Tomography or PET scans are the two most common imaging modalities in nuclear medicine.
(核医学)。
概述:核医学程序有时被描述为“由内而外”的x射线,因为它记录的是从患者身体发出的辐射,而不是直接穿过患者身体的辐射。核医学程序使用少量的放射性物质,称为放射性药物,来创建解剖图像。放射性药物是被特定器官、骨骼或组织吸引的物质。它们通过注射、吞咽或吸入进入病人体内。当放射性药物在体内传播时,它会产生放射性排放物。一种特殊类型的照相机检测器官、骨骼或被成像组织中的这些辐射,然后将这些信息记录在电脑屏幕和胶片上。
