Iodine i-131 sodium iodide, diagnostic, per microcurie (up to 100 microcuries)

HCPCS code

Name of the Procedure:

Diagnostic Iodine I-131 Sodium Iodide Administration
Common name(s): I-131 Imaging, Iodine Scanning
Technical/Medical term: Iodine I-131 Sodium Iodide Diagnostic Procedure

Summary

This procedure involves administering a small, controlled dose of radioactive iodine (I-131 sodium iodide) to help doctors visualize and diagnose conditions affecting glands like the thyroid. It’s a non-invasive way to detect abnormalities.

Purpose

This procedure is used to diagnose conditions such as thyroid disorders, including hyperthyroidism and thyroid cancer. It helps in imaging and functional studies of the thyroid gland to assess its health and functionality.

Indications

  • Suspected thyroid disorders such as Graves' disease or thyroid nodules
  • Monitoring the spread or recurrence of thyroid cancer
  • Evaluation of hyperthyroidism or hypothyroidism
  • Cases needing fine-tuning of thyroid treatment plans

    Preparation

  • Patients may be advised to fast for a few hours before the procedure.
  • Patients should avoid foods and medications containing iodine several days prior.
  • Diagnostic blood tests to measure thyroid hormone levels may be conducted beforehand.
  • Patients should notify their doctor of any medications or supplements they are taking.

Procedure Description

  1. The patient is given a small dose of I-131 sodium iodide, typically administered orally in capsule or liquid form.
  2. Following administration, the patient may be asked to wait as the radioactive iodine is absorbed by the thyroid.
  3. Imaging tests, such as a gamma camera scan, are performed at specific intervals post-administration to capture images of the thyroid gland.
  4. Throughout the procedure, specialized equipment will track the radiation emitted by the I-131, allowing doctors to create detailed images.
  5. No anesthesia or sedation is typically required for this non-invasive diagnostic procedure.

Duration

The actual administration of the I-131 takes only a few minutes, but imaging may be conducted over several hours or even over a few days, depending on the specific diagnostic needs.

Setting

The procedure is generally performed in a hospital’s nuclear medicine department or an outpatient imaging clinic.

Personnel

  • Nuclear Medicine Physicians
  • Radiologic Technologists
  • Nurses specialized in nuclear medicine

Risks and Complications

  • Minor side effects like nausea or a metallic taste.
  • Allergic reactions are rare but possible.
  • Radiation exposure is minimal and generally considered safe for most patients.
  • Pregnant women or those breastfeeding may need to avoid this procedure due to radiation risk.

Benefits

  • Provides detailed and accurate imaging of the thyroid gland.
  • Helps in early detection and precise treatment planning for thyroid disorders.
  • Results are usually available within a few days, allowing for timely diagnosis.

Recovery

  • Post-procedure, patients can resume normal activities almost immediately.
  • Hydrating well helps eliminate the radioactive material from the body.
  • Follow-up appointments may be necessary based on the findings and the patient’s condition.

Alternatives

  • Ultrasound imaging of the thyroid
  • Blood tests for thyroid hormone levels
  • CT or MRI scans for detailed imaging
  • Each alternative has its own advantages and limitations; for example, ultrasounds are non-invasive but less detailed than I-131 imaging.

Patient Experience

  • During the procedure, patients might feel anxious about the radioactive material, but it's generally well-tolerated.
  • Patients might need to stay at the facility for a while after taking the dose for scheduled imaging.
  • Any discomfort is usually minimal, involving mostly waiting times between dose and imaging.
