Name of the Procedure:
Radiopharmaceutical Localization of Tumor, Inflammatory Process, or Distribution of Radiopharmaceutical Agent(s); Tomographic (SPECT) with Concurrently Acquired Computed Tomography (CT) Transmission.
Common name(s): SPECT-CT scan
Summary
A SPECT-CT scan combines two different imaging techniques, Single Photon Emission Computed Tomography (SPECT) and Computed Tomography (CT), to provide detailed images of the inside of your body. This procedure uses a small amount of radioactive material to help doctors locate tumors, areas of inflammation, or other abnormalities accurately.
Purpose
This procedure is used to detect and locate tumors, inflammation, or to track the distribution of radiopharmaceutical agents in the body. The goal is to provide clear and precise images that can guide diagnosis and treatment planning.
Indications
- Suspicion of cancer or tumor.
- Unexplained pain or swelling indicating possible inflammation.
- Monitoring known tumors or inflammatory conditions.
Assessing blood flow and function of specific organs.
Preparation
- You may be asked to fast for a few hours before the procedure.
- Inform your doctor of any medications you are taking; some may need to be adjusted.
- You might undergo blood tests or other imaging tests prior to the procedure.
- You will need to remove any metal objects like jewelry or eyeglasses.
Procedure Description
- Injection of Radiopharmaceutical: A small amount of radioactive material is injected into a vein.
- Waiting Period: You may wait for about 30-60 minutes to allow the radiopharmaceutical to distribute in your body.
- SPECT Imaging: You will lie on a table that slides into the SPECT scanner, which rotates around you to capture detailed images.
- CT Imaging: Concurrently, a CT scan is performed to provide additional anatomical details.
- Image Processing: The combined SPECT and CT images are processed to create a detailed view of the target area.
Tools and Equipment: SPECT scanner, CT scanner, and radiopharmaceutical agent.
Anesthesia: This procedure typically doesn’t require anesthesia or sedation.
Duration
The entire procedure usually takes about 1.5 to 2 hours.
Setting
This procedure is performed in a hospital’s nuclear medicine department or an outpatient imaging center equipped with SPECT-CT technology.
Personnel
- Nuclear medicine physician
- Radiologist
- Nuclear medicine technologist
- Radiologic technologist
Risks and Complications
- Common Risks: Mild reactions to the radiopharmaceutical, such as rash or nausea.
- Rare Risks: Radiation exposure poses a small risk, but the benefits typically outweigh this.
- Management: Any complications will be managed by the medical team present.
Benefits
- Accuracy: Provides highly detailed images for accurate diagnosis.
- Early Detection: Helps in early detection and monitoring of tumors and inflammatory processes.
- Guided Treatment: Aids in guiding surgeries or other treatments with precision.
Recovery
- Post-Procedure Care: No significant aftercare required; you can usually resume normal activities immediately.
- Recovery Time: Immediate.
- Follow-Up: Your doctor will discuss the results with you and explain any further steps or treatments.
Alternatives
- Alternative Imaging: MRI or PET scans.
- Pros and Cons: MRI does not use radiation but may not provide as detailed functional information. PET scans are similar but may be more expensive and less available.
Patient Experience
- During the Procedure: You might feel a slight prick during the injection and need to lie still during imaging.
- After the Procedure: Minimal discomfort; most patients experience no side effects. Drinking plenty of fluids can help flush the radiopharmaceutical from your body more quickly.
Pain management and comfort measures are usually not needed due to the non-invasive nature of the procedure.
