淋巴闪烁扫描术

Lymphoscintigraphy is used to study the flow of lymphatic fluid in the body.
这是用来研究体内淋巴液流动的一种检查方法。
The procedure involves injecting a radioactive tracer into the skin.
该过程包括向皮肤注入一种放射性示踪剂。
It helps diagnose lymphedema, a condition where swelling occurs in the limbs due to impaired lymph flow.
它有助于诊断淋巴水肿，即由于淋巴液流动受阻导致肢体肿胀的情况。
A gamma camera captures images of the tracer's movement through the lymph nodes.
伽马相机捕捉到示踪剂在淋巴结中移动的图像。
The test may show blockages or abnormalities in the lymphatic system.
该测试可能显示淋巴系统中的阻塞或异常。
Lymphoscintigraphy is particularly useful for planning lymph node dissections in cancer surgery.
对于癌症手术中的淋巴结清扫计划，淋巴显像特别有用。
The patient is asked to move their limbs during the scan to observe the tracer's dynamics.
患者在扫描过程中被要求移动肢体，以观察示踪剂的动态。
Results from lymphoscintigraphy can guide radiation therapy targeting affected lymph nodes.
淋巴显像的结果可以指导针对受影响淋巴结的放疗。
This imaging technique is non-invasive and minimally painful for the patient.
这种成像技术对患者来说是非侵入性的，且痛苦较小。
After the procedure, patients typically rest for a few hours before leaving the facility.
手术后，患者通常需要休息几个小时才能离开医疗机构。
