Ultrasound of the lymph nodes (1 area or group)

About the Examination

Ultrasound examination is an advanced, non-invasive diagnostic method used to assess internal tissues, organs, and other body structures using high-frequency sound waves. This examination is quick, safe, and has no harmful side effects. It is performed using an ultrasound machine consisting of a transducer and a monitor. As the transducer is moved over the skin, ultrasound waves are reflected by the body's tissues and converted into electrical signals, which create images on the screen. This allows the doctor to examine internal organs without affecting the body's integrity.

What Is This Examination Used For?

This examination may be prescribed to investigate pain, abnormalities, lumps, masses, or other changes affecting the heart, thyroid gland, abdominal organs (liver, gallbladder, pancreas, spleen), urinary system (kidneys, urinary bladder, post-void residual urine), prostate, breasts, lymph nodes, and joints.

As a preventive measure, an ultrasound examination is recommended annually for older adults.

How to Prepare for an Ultrasound Examination

Abdominal Ultrasound Examination

• Gallbladder examination – it is recommended not to eat for approximately 4 hours before the examination.
• Pancreas and spleen examination:
• • For 24 hours before the examination, it is recommended to avoid foods that may cause bloating (such as rye bread, apples, plums, peas, beer, etc.).
  • Approximately 8 hours before the examination, take medication intended to reduce bloating.

Urinary System and Reproductive Organ Ultrasound Examination

• Drink fluids before the examination. The urinary bladder should be full during the procedure.

No special preparation is required for other ultrasound examinations.

What Happens During the Examination?

An ultrasound examination may be performed by placing the transducer on the skin over the area being examined or by inserting a specialized transducer through a natural body opening.

When performed through the skin, the examination is usually carried out with the patient lying on their back. Depending on the organ being examined, the doctor may ask you to stand, turn onto your side, or lie on your stomach.

A special water-based gel will be applied to your skin to eliminate the air gap between the skin and the transducer, ensuring more accurate imaging. The doctor will then place the transducer against the skin and move it over the area of interest to obtain detailed images on the monitor.

When the examination is performed through a natural body opening:

• During transesophageal ultrasound, the transducer is inserted into the esophagus to obtain detailed images of the heart.
• During transrectal ultrasound, the transducer is inserted into the rectum to examine the prostate gland.
• During transvaginal ultrasound, the transducer is inserted into the vagina to examine the uterus and ovaries.

After the Examination

The doctor will discuss the examination results with you and, if necessary, recommend appropriate treatment.
