Lymph node ultrasound is an imaging technique used to evaluate changes in the lymphatic system. This method helps detect enlargement, inflammation, or tumor involvement of lymph nodes, which may indicate various conditions, including infections and malignant diseases.
When is lymph node ultrasound indicated?
Lymph node ultrasound is recommended in the following situations:
- Enlarged lymph nodes — especially if they become painful or increase in size without an obvious cause.
- Suspected infectious diseases such as infectious mononucleosis, tuberculosis, or other bacterial and viral infections.
- Lymphoma or other cancers with suspected lymph node metastasis.
- Immune system disorders, including autoimmune diseases or chronic inflammatory conditions.
- Painful lymph nodes in the neck, axillary, or inguinal regions.
Advantages of lymph node ultrasound
- Safety — ultrasound does not use ionizing radiation and is completely safe for the body.
- Accuracy — allows detailed assessment of lymph node size, structure, and internal architecture, including detection of suspicious changes.
- Painlessness — the procedure is non-invasive and does not cause discomfort.
- Accessibility — widely available in most medical facilities and performed quickly.
How is lymph node ultrasound performed?
The lymph node ultrasound procedure usually takes about 10–15 minutes. The patient lies in a comfortable position while the physician applies a special gel to the skin to ensure optimal contact with the ultrasound transducer. The transducer is moved over the neck, armpits, groin, or other regions where lymph nodes are located. The examination allows evaluation of lymph node size, shape, and internal structure.
In some cases, additional diagnostic tests may be recommended if suspicious changes are detected during the ultrasound examination.
Lymph node ultrasound is available in leading clinics in Belarus, where experienced specialists provide accurate evaluation of the lymphatic system and recommend appropriate further management.
