Brachytherapy is a type of radiation therapy used to treat cancer. Doses of radioactive material are placed directly on target areas to kill cancer cells and shrink tumors.

Background Information:

What are the other Names for the Procedure?

  • Internal Radiation Therapy
  • Interstitial Brachytherapy
  • Intracavity Brachytherapy

What is Brachytherapy radiology procedure? (General Explanation)

  • Brachytherapy is a type of radiation therapy used to treat cancer. Doses of radioactive material are placed directly on target areas to kill cancer cells and shrink tumors
  • The radioactive material is placed inside a catheter for a certain amount of time and removed in Temporary Brachytherapy. Temporary Brachytherapy can be applied at a high-dose rate (HDR) or low-dose rate (LDR)
  • In Permanent Brachytherapy, radioactive material is left in or near the tumor permanently. Radioactivity of this material eventually diminishes to very small levels, ultimately not producing any radioactivity at all
  • Brachytherapy can be used to treat various types of cancers such as those affecting the eye, rectum, breast, lung, vagina, uterus, prostate, cervix, head and neck, skin, and gallbladder

What part of the Body does the Procedure involve?

A Brachytherapy procedure may involve any of the following body parts, and this depends on the location of the cancer.

  • Prostate
  • Head and neck
  • Breast
  • Gallbladder
  • Uterus
  • Vagina
  • Lung
  • Rectum
  • Eye

Why is the Brachytherapy radiology procedure Performed?

Brachytherapy is used to treat cervical, prostate, breast, and skin cancer. Tumors located at other body sites can be treated as well.

What is the Equipment used? (Description of Equipment)

The equipment for Brachytherapy procedure includes:

  • Radioactive material encapsulated in a metal capsule is placed near the site of the tumor using a delivery device in permanent implants
  • In temporary implants, plastic catheter or needles are placed on the treatment site
  • Different types of radioactive materials such as palladium, cesium, iridium, or iodine, can be used in Brachytherapy
  • An MRI scan, CT scan, ultrasound, or X-ray scan may be used to position the radioactive material near the tumor
  • A computer calculates the exact position for the placement of the radioactive material and desired dose of radiation
  • In all of these procedures, the source of radiation is encapsulated in a metal capsule, so that the radioactive material does not enter the patient’s body

What are the Recent Advances in the Procedure?

There have been no recent advances with respect to the Brachytherapy procedure.

What is the Cost of performing the Brachytherapy radiology procedure?

The cost of the Brachytherapy procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.

In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.

When do you need a Second Opinion, prior to the Procedure?

  • It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding the Brachytherapy procedure and what needs to be done
  • If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician
  • Also, if the procedure involves multiple steps or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently

Prior to Brachytherapy radiology procedure:

How does the Brachytherapy radiology procedure work?

  • Brachytherapy can be used alone or in conjunction with other therapies, such as surgery, external beam radiotherapy (EBRT), and chemotherapy
  • EBRT involves high-energy X-ray beams produced by a machine that are directed at the tumor or cancer cells from outside the body

How is the Brachytherapy radiology procedure Performed?

Permanent Brachytherapy is performed as follows:

  • Needles or specific delivery devices filled with radioactive materials are inserted into the tumor
  • The needle or delivery device is removed and radioactive material is left in the tumor permanently
  • Imaging techniques, such as an X-ray, MRI scan, ultrasound, or CT scan, are used for the placement of the material

Temporary Brachytherapy is performed as follows:

  • By using imaging techniques, such as a CT scan, MRI, ultrasound, or fluoroscopy, the delivery device filled with radioactive material is placed into the tumor
  • In Intracavity Brachytherapy, the delivery device is placed in body cavities such as the vagina or uterus
  • In Interstitial Brachytherapy, the delivery device is inserted into body tissues
  • High-dose rate (HDR):
    • In HDR, the radiation is delivered in short bursts to the tumor
    • The treatment is delivered at the rate of 10-20 minutes per session
    • Treatment is repeated several times, if necessary, and the delivery device is removed from the body
    • It is possible that the patient may receive up to 10 HDR Brachytherapy sessions over one or more weeks
  • Low-dose rate (LDR):
    • The treatment is delivered at the rate of 20-50 hours
    • In LDR, the radiation is delivered at a continuous rate over one or two days. The patient is required to stay overnight in the hospital
  • Pulse dose rate (PDR):
    • The treatment is delivered in periodic pulses, rather than continuously

Where is the Procedure Performed?

Brachytherapy is usually an outpatient procedure. Sometimes, the patient is admitted to the hospital for one or two days for additional treatment. 

Who Performs the Procedure?

The equipment for Brachytherapy treatment is operated by a medical physicist, a licensed dosimetrist (supervised by a physicist), or a radiation oncologist. The general treatment plan is created by a radiation oncologist.

How long will the Procedure take?

The actual treatment lasts about 10-20 minutes, though the entire Brachytherapy procedure may last for a few hours.

Who interprets the Result?

  • The radiation oncologist determines proper therapy for the patient, what area of the body is to be treated, and how much radiation is to be delivered
  • The medical physicist and dosimetrist makes treatment calculations and determines the method of radiation dose delivery
  • The radiation therapist assists in the delivery of the treatment; help from surgeons may be necessary, in case catheters or needles are necessary for the treatment
  • Brachytherapy needs a medical team consisting of a medical physicist, dosimetrist, radiation therapist, nurse, surgeon, and a radiation oncologist

What Preparations are needed, prior to the Procedure?

The following preparations may be needed prior to a Brachytherapy procedure:

  • The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient, including information related to the medications that are currently being taken
  • Do inform the medical professional if you have a history of any medical conditions such as a heart disease, asthma, diabetes, or kidney disease
  • Do inform the medical professional about any allergies, especially related to barium or iodinated contrast material, which may be used in the procedure
  • It is advisable to wear comfortable and loose clothes. Avoid wearing any metal objects or jewelry, as it may interfere with the X-ray
  • Women should notify the physician if they are pregnant or breastfeeding their child, as many such procedures may not be performed on pregnant women
  • Depending on the procedure adopted, the patient may be asked for certain bowel or bladder preparations before the preparation sessions
  • The patient may be asked to avoid eating or drinking several hours before the test
  • The physician may ask the patient to go through bowel preparation, blood tests, ultrasound, MRI or CT scan, EKG, or chest X-ray before the procedure, if necessary
  • Specific instructions are given to the patient on how to prepare for the Brachytherapy procedure a few days before the actual procedure

What is the Consent Process before the Procedure?

A physician will request your consent for a Brachytherapy procedure using an Informed Consent Form

Consent for the Procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent

You must sign the forms only after you are totally satisfied with the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure
