Stereotactic biopsy

Stereotactic biopsy is a type of biopsy that uses a computer and imaging performed in at least two planes to localize a target lesion such as a tumor or microcalcifications in the body. The procedure is used to determine the nature of a lesion in the body.

Procedure

The patient is positioned so that the lesion can be accurately targeted. The computer calculates the position and depth of the lesion, and the radiologist or surgeon uses this information to guide the biopsy needle to the precise location. The procedure is minimally invasive and usually performed under local anesthesia.

Uses

Stereotactic biopsy is often used when a lesion is difficult to reach or when it is not visible through other methods such as ultrasound or mammography. It is commonly used in the diagnosis of breast cancer, brain tumors, and other conditions.

Advantages

The main advantage of stereotactic biopsy is its precision. It allows for accurate targeting of lesions, reducing the risk of damage to surrounding tissues. It is also less invasive than surgical biopsy, resulting in less pain and quicker recovery for the patient.

Risks

As with any procedure, there are risks associated with stereotactic biopsy. These may include infection, bleeding, and an adverse reaction to anesthesia. There is also a small risk that the biopsy will not provide a definitive diagnosis, necessitating further testing.
