Our PET/CT Scan offers Time of Flight (TOF) technology, which provides higher image quality for more accurate disease detection. Your images will be read by one of our fellowship-trained sub-specialized and board certified radiologists.
The fusion of PET and CT imaging allows the radiologist to combine information from two different exams in one study. This leads to more precise information and more exact diagnosis. Accurate diagnosis can reduce the need for biopsies or surgeries. Diagnoses can be made earlier and with greater accuracy, allowing for better treatment planning and improved patient care.
PET/CT scans are covered by Medicare, Medicaid, and private insurance companies.
In Oncological applications, PET/CT scanning is performed by injecting the patient’s arm with a radioactive sugar (glucose) called FDG-18 (Fluorodeoxyglucose.) After waiting at least an hour to allow the sugar to circulate, the PET/CT scan is then administered. Cancerous cells are metabolically more active than normal cells, and therefore metabolize more sugar for energy. Because of this, cancer cells then appear as “hot-spots” compared to normal cells.
The PET component measures these “hot-spots” while the CT component supplies anatomical reference points. Fusing the components together allows our Board Certified Radiologists to pinpoint the location of the abnormality.
Neurology (Brain Function)
Prior to your scheduled appointment, you will be contacted by our staff to review how to prepare for your scan and answer your questions. Please inform the staff if you are diabetic and/or claustrophobic. Free transportation is available if needed.
BEFORE YOUR APPOINTMENT:
48 Hours before your scan – Do not do any strenuous exercise or deep-tissue massage.
24 Hours before your scan – Stay on a VERY LOW-carbohydrate, NO-sugar diet. Do NOT chew gum or mints. Drink 40 oz. of water the evening before your scan.
6 Hours before your scan – Do NOT eat anything. Drink 32 oz. of water only. Hydration will insure that you have an accurate scan. Continue to take medications as prescribed, if tolerated on an empty stomach.
WHAT TO BRING TO YOUR APPOINTMENT:
You should wear warm comfortable loose fitting clothing, free of metal snaps, buttons and/or pendants. Do NOT wear jewelry. Bring films and reports of your prior exams and a list of your medications.
IT IS EXTREMELY IMPORTANT THAT PATIENT ARRIVES ON TIME:
Isotopes have been ordered specific for your appointment time. Isotopes have a short shelf-life and they need to be fresh to obtain accurate images. If you cannot arrive on time or if you need to reschedule your appointment, please call us ASAP.
After reviewing your medical history, our highly trained technician will inject you with a isotope/contrast agent (FDG-18 or F-18-NaF) and instruct you to rest, minimizing any type of physical activity. The resting period (or uptake time) varies depending on the type of PET/CT Scan being administered.
After resting you will be asked to lie flat on a PET/CT table which will then move towards the specific areas of the body that are being examined. During the exam you will be able to see all around you, as you are never fully enclosed in our open design PET/CT.
The technologist will be in communication with you via a two-way microphone as you are constantly visually monitored throughout the exam. Scan time on the table is approximately 30 minutes, but total exam time can range anywhere from 2 to 3 hours – allowing time for the computer to generate the images as well as preparation time for the patient and contrast uptake. After the exam you will be helped off the table and given juice.
Your images will be read by one of our board-certified radiologists and the report will be sent to your physician. When your scan is completed, you will be free to go home. There are no restrictions on what you eat or drink. We encourage you to drink extra fluids after your scan.
