Gamma probe

Gamma Probe is a medical device used in nuclear medicine and oncology to locate lymph nodes and tumors. It is particularly useful in the detection of breast cancer and melanoma.

Overview

A gamma probe is a handheld device that detects gamma rays. It is used during surgery to help locate lymph nodes and tumors. The probe is used in conjunction with a radiopharmaceutical, which is injected into the patient prior to surgery. The radiopharmaceutical emits gamma rays, which are then detected by the probe.

Use in Surgery

During surgery, the gamma probe is used to scan the patient's body. The probe is moved over the skin, and when it detects gamma rays, it emits a sound. The louder the sound, the closer the probe is to the source of the gamma rays. This allows the surgeon to locate and remove lymph nodes and tumors with greater precision.

Advantages

The use of a gamma probe has several advantages. It allows for more precise localization of lymph nodes and tumors, which can lead to more effective treatment. It also reduces the need for more invasive procedures, such as lymphadenectomy, which involves the removal of many lymph nodes.

Risks

As with any medical procedure, there are risks associated with the use of a gamma probe. These include the risk of infection, bleeding, and allergic reaction to the radiopharmaceutical. However, these risks are generally low.
