A lymph node ultrasound is a non-invasive, radiation-free imaging test used to assess swollen or abnormal lymph nodes in various parts of the body.

What It Evaluates:

✅ Lymph Node Enlargement – Checks for swollen nodes due to infections, inflammation, or other conditions.
✅ Lymph Node Shape & Size – Differentiates between normal and abnormal lymph nodes.
✅ Benign vs. Suspicious Lymph Nodes – Assesses for irregular borders, internal blood flow, or other signs of malignancy.
✅ Infections & Inflammation – Helps diagnose reactive lymph nodes due to bacterial or viral infections.
✅ Lymphoma & Metastasis – Evaluates nodes for cancer spread from other areas (e.g., breast, lung, or melanoma).
✅ Fluid Collections or Abscesses – Identifies infected lymph nodes with pus or fluid buildup.
✅ Neck, Groin, or Axillary (Armpit) Lymph Nodes – Examines different regions depending on symptoms.
