Spine SPECT-CT – About the Exam
A Spine Single Phonton Emission Computed Tomography (SPECT) uses a gamma camera to create images of the spine in three different planes and helps the nuclear medicine radiologist to "see around" body parts that may be in the way.
The gamma camera rotates around the body collecting data about your spine during each stop of the rotation. A computer takes all of that data and creates images, or slices, of the spine looking front to back, side to side and top to bottom. By combining the functionality of SPECT imaging and the anatomical detail of a CT scan, a Mountain Medical nuclear medicine radiologist is able to precisely pinpoint the exact location of that “hot-spot” in the spine.
What you can expect during a spine SPECT-CT:
- The SPECT-CT procedure is usually performed on an outpatient basis.
- You will be asked to lie on the examination table. If necessary, a nurse or technologist will insert an intravenous (IV) catheter into a vein in your hand or arm.
- Depending on the type of nuclear medicine exam you are undergoing, the dose of radiotracer is then injected intravenously, swallowed or inhaled as a gas.
- It typically takes about 60 minutes for the radiotracer to be absorbed by your body so that your tissues can be studied. During this time you will be asked to rest quietly on the table.
- You may be asked to drink a contrast material to help the radiologist interpreting the study.
- Once the CT scan is started, the examination table will start moving while your spine is being imaged.
- You may be asked to remain still and even hold your breath for very short periods during the exam.
- The exam time is approximately 30 minutes.
