Lymphoscintigraphy has introduced with the great advantage for diagnostic imaging of the lymphatic flow disorders. Lymphoscintigraphy can be performed in patients of any age, including neonates, and even in patient in critical conditions. The procedure is quite simple, and it needs only subcutaneous injection of small amounts of radiotracers. From subcutaneous tissue the radiotracer is taken by the lymphatic vessels and gives off energy in the form of gamma radiation detected by a gamma camera. Radiotracers rarely cause the allergic reaction and can be administered to the patients with allergy to iodine contrast media. Comparing with the Lipiodol, radiotracers cannot cause pulmonary embolism; therefore, it is safe for the patients with respiratory dysfunction. The objective of this article is to describe the indication, technique, equipment, pitfalls, safety, and effectiveness of lymphoscintigraphy for imaging of the lymphatic flow disorders.
淋巴闪烁造影术的引入为淋巴流动障碍的诊断成像带来了巨大优势。淋巴闪烁造影术适用于任何年龄段的患者，包括新生儿，甚至是病情危急的患者。该检查过程非常简单，仅需皮下注射少量放射性示踪剂。放射性示踪剂从皮下组织被淋巴管摄取，并以伽马射线的形式释放能量，由伽马相机检测。放射性示踪剂很少引起过敏反应，可用于对碘造影剂过敏的患者。与碘油相比，放射性示踪剂不会导致肺栓塞；因此，对呼吸功能不全的患者来说是安全的。本文的目的是描述淋巴闪烁造影术在淋巴流动障碍成像方面的适应证、技术、设备、陷阱、安全性和有效性。
