Technetium tc-99m pertechnetate, diagnostic, per millicurie

HCPCS code

Name of the Procedure:

Technetium Tc-99m Pertechnetate Diagnostic Imaging
Technical Terms: Radiopharmaceutical Diagnostic Imaging using Technetium Tc-99m Pertechnetate (HCPCS code A9512).


Technetium Tc-99m pertechnetate is a radiopharmaceutical agent used in diagnostic imaging. It involves injecting a small amount of a radioactive substance into the body, which is then captured on camera to help visualize and diagnose various conditions.


Technetium Tc-99m pertechnetate imaging is used to diagnose a wide range of medical conditions, including thyroid disorders, gastrointestinal bleeding, and certain types of tumors. The goal is to provide clear images of specific organs or tissues to help doctors accurately diagnose and evaluate the patient's condition.


  • Thyroid disorders (e.g., hyperthyroidism, thyroid nodules)
  • Detection of gastrointestinal bleeding
  • Evaluation of Meckel's diverticulum
  • Tumor localization
  • Assessment of salivary gland function
  • Scanning for parathyroid adenomas


  • Patients may be advised to fast for several hours before the procedure, depending on the specific study.
  • Certain medications may need to be adjusted or temporarily discontinued.
  • A thorough medical history and any recent diagnostic tests should be reviewed with the healthcare provider.

Procedure Description

  1. Preparation: The patient may need to change into a gown and remove any metal objects.
  2. Injection: A small dose of Technetium Tc-99m pertechnetate is injected intravenously.
  3. Imaging: After the injection, the patient is positioned under a gamma camera that captures images of the radiopharmaceutical distribution in the body.
  4. Analysis: The images are analyzed by a radiologist to assess the function and structure of the targeted tissues or organs.

Tools & Equipment:

  • Gamma camera
  • Intravenous (IV) line for injection
  • Radiopharmaceutical dose of Technetium Tc-99m pertechnetate


The entire process typically takes between 1 to 2 hours, depending on the specific diagnostic study being performed.


The procedure is usually carried out in a hospital's nuclear medicine department or an outpatient imaging center.


  • Nuclear medicine technologist
  • Radiologist or nuclear medicine physician
  • Nurses and support staff

Risks and Complications

  • Minimal exposure to radiation (generally low risk)
  • Allergic reaction to the radiopharmaceutical (rare)
  • Bruising or discomfort at the injection site


  • Non-invasive and highly effective for diagnosing a variety of conditions.
  • Provides detailed and functional imaging of organs and tissues.
  • Quick return to normal activities, usually with minimal side effects.


  • Most patients can resume normal activities immediately after the procedure.
  • It is necessary to drink plenty of fluids to help flush the radioactive substance from the body.
  • Follow-up appointments may be required to discuss the results with the healthcare provider.


  • Magnetic Resonance Imaging (MRI)
  • Computed Tomography (CT) scans
  • Ultrasound
  • Laboratory tests Each alternative has its pros and cons, such as varying levels of detail, invasiveness, and exposure to radiation.

Patient Experience

  • During the injection, patients might feel a slight prick.
  • While the images are being taken, it is important to stay still to ensure clear images.
  • The procedure generally involves minimal discomfort, and pain management is rarely necessary.
