nyirokvizsgálati

Nyirokvizsgálati refers to the examination of the lymphatic system. The lymphatic system is a crucial part of the immune system and the circulatory system, responsible for transporting lymph fluid, a clear or yellowish fluid containing white blood cells, throughout the body. This fluid helps to fight infection and remove waste products.

Lymphatic examinations can involve several methods. Palpation of lymph nodes is a common initial step, where a healthcare professional feels for enlarged, tender, or firm lymph nodes, particularly in areas like the neck, armpits, and groin. Enlarged lymph nodes can indicate infection, inflammation, or malignancy.

Imaging techniques are also frequently used. Ultrasound can visualize lymph nodes and surrounding tissues, helping to assess their size, shape, and internal structure. CT scans and MRI scans provide more detailed cross-sectional images of the lymphatic system, useful for identifying abnormalities or staging diseases.

Biopsies are sometimes necessary for a definitive diagnosis. A fine-needle aspiration (FNA) involves extracting a small sample of cells from a suspicious lymph node using a thin needle. A core needle biopsy or an excisional biopsy removes a larger piece of tissue for more extensive analysis under a microscope. These procedures help determine the cause of lymph node enlargement, such as lymphoma, metastasis from other cancers, or infectious diseases.

Understanding the lymphatic system through nyirokvizsgálati is vital for diagnosing and managing a wide range of conditions affecting immunity, infection, and cancer spread.
