A Computed Tomography (CT) scan uses a computer and x-rays to provide cross-sectional images (often called slices) of body tissues and organs. These images can show the presence of a tumor, its extent and if it has spread beyond the local site. Once the scan is completed it is sent to an expert radiologist for interpretation.
Our oncologists then receive the results and use them to define the best course of treatment for you as well as monitoring your current cancer treatment plan. CT scans are painless, non-invasive and carry minimal risks.
Oral contrast in the form of barium or water is used when an abdomen or pelvis are scanned. IV contrast is often ordered to better define a tumor’s borders and the body’s vascular structures. If IV contrast is ordered, you will be asked to have labs drawn to assess kidney function.
A CT scan is done as an outpatient and scans take five to fifteen minutes.
PET SCAN / CT SCAN
A PET/CT scan is an advanced imaging technology that combines Positron Emission Tomography (PET) and computed tomography (CT). The PET component focuses on the tissue’s biologic characteristics, while the CT provides structural anatomic information.
The resulting detailed three dimensional imaging helps physicians detect solid cancer tumors even in their earliest stages, making PET/CT one of the most accurate diagnostic scans available. A PET/CT scan can often reduce the need for further testing and invasive surgeries.
As part of the procedure a small amount of a radioactive tracer is injected into your bloodstream. This safe, effective substance will be distributed throughout your body according to the characteristics of the tracer. There are no side effects and the material injected will be metabolized by your kidneys and excreted through your bladder. After your injection, you will be asked to relax and remain relatively still for about 45 minutes or in some cases, your scan will begin immediately.
Next, you will be asked to lie on a table called a “scanning bed”. The bed will move slowly through the scanner while the machine detects the injected tracer.
When the imaging procedure is complete, the scanner will send the resulting information to a specially trained radiologist who reads and interprets the PET/CT and then sends the results to your oncologist who will use them in the development of your personalized cancer treatment plan.
The time of the actual scan can vary from 15 minutes for images focused on the brain, to 35 minutes for an entire body scan. We ask cancer patients and their caregivers to plan on being at the cancer center for 1 ½ – 3 hours.
PET/CT scans available at RMCC are:
- 18FDG – Fluorodeoxyglucose Pre-Procedure Preparation for 18FDG-Fluorodeoxyglucose
- NETSPOT – Ga68 DOTATATE Pre-procedure Preparation for Ga68 DOTATATE – The FDA approved Ga-68 DOTATATE PET/CT is for patients with neuroendocrine tumors (NETs). Netspot™, gallium 68 DOTATATE is a radioactive diagnostic agent used in positron emission tomography (PET) imaging. Because the gallium DOTATATE binds strongly to the receptors of neuroendocrine tumor cells, it effectively detects tumors and metastases, not seen on other standard scans, and reveals the locations of tumors.
The Netspot Ga-68 DOTATATE PET/CT is available at the Rocky Mountain Cancer Centers Midtown location, centrally located near downtown Denver.
- 18NaF – Sodium Fluoride PET bone Pre-procedure Preparation for 18NaF-Sodium Fluoride PET Bone
- Axumin – Fluciclovine F18 Pre-Procedure Preparation for Axumin PET/CT – Axumin® PET/CT is for patients with recurrent prostate cancer. Axumin can detect recurrent disease with PSA levels less than 10 and sometimes much lower. This is an important differentiator since current diagnostic imaging bone and body scans are typically limited in detecting biochemical recurrence until PSA values are elevated 10 to 30 or higher.
With Axumin PET/CT, the F18, a synthetic amino acid, injected prior to the PET/CT enhances the prostate cancer cells and allows their exact location to be pinpointed. Knowing the exact location early in relapse has been shown to be an invaluable tool for urologists and radiation oncologists in planning secondary treatment options and improving outcomes.
The Axumin PET/CT takes about an hour to complete and requires very little pre-procedure preparation.
