What is Nuclear Medicine SPECT/CT?
A SPECT/CT scan combines Single-Photon Emission Computed Tomography (SPECT) with Computed Tomography (CT) to provide both functional and anatomical information. This combination enhances the accuracy of diagnoses by merging the functional data from SPECT with the detailed anatomical images from CT12.
How Does It Work?
Preparation:
- Clothing: Wear loose, comfortable clothing without metal zippers, buttons, or belts.
- Remove Metal Items: You’ll need to remove any metal objects, such as jewelry, as they can interfere with the imaging.
- Medical Records: Bring any relevant medical documents or instructions from your doctor. Bring CD image and report from prior Spect/CT scan to be compared if necessary.
- Dietary Restrictions: Depending on the type of scan, you may need to follow specific dietary restrictions2.
During the scan
- Radiotracer Administration: You’ll receive a radiotracer, which can be injected. This substance emits gamma rays that are detected by the SPECT camera3.
- Positioning: You’ll lie on a motorized table that slides into the SPECT/CT scanner. The scanner captures both SPECT and CT images.
- Imaging: The SPECT component captures functional images by detecting gamma rays emitted by the radiotracer. The CT component provides detailed anatomical images. These images are then fused to create a comprehensive view of the area being examined12.
Procedure:
- Stay Still: It’s important to remain still during the scan to ensure clear images.
- Duration: The scan itself usually takes between 30 to 60 minutes, depending on the area being examined2.
What to Expect?
- Comfort: The procedure is generally painless, though lying still might be uncomfortable for some.
- Radiation: The level of radiation exposure is relatively low and considered safe for most patients2.
- Results: The images help doctors diagnose conditions, plan treatments, and guide procedures.
After the Scan:
- Hydration: Drink plenty of fluids to help flush the radiotracer from your body.
- Normal Activities: You can usually resume normal activities immediately after the scan.
- Follow-Up: Your doctor will review the images and discuss the results with you.
Common Uses of SPECT/CT:
- Oncology: Identifying and monitoring tumors.
- Neurology: Evaluating brain disorders such as epilepsy and Alzheimer’s disease.
- Orthopedics: Diagnosing bone disorders and infections.
