| Beverages: alcoholic beverages, soft drinks, juices, sugar teas, coconut water, mate tea and green tea, and milk of animal origin | – |
On the day of the exam:
ü Fasting from food: A 6-hour fast must be observed before the exam.ü Fasting from Water: For patients who will use iodinated contrast (radiological contrast), it is necessary to stop drinking water at least 2 hours before the exam. This measure aims to prevent vomiting and possible aspirations. (If there is no prescription for iodinated contrast by the requesting physician or the responsible nuclear physician, water intake is permitted).ü Medications: There is no need to stop taking any medications, except in cases of diabetic patients who are taking metformin and who will undergo the exam using iodinated contrast. In this case, metformin should be stopped on the day of the exam and for 48 hours after the exam.ü Insulin: Diabetic patients who use insulin should not apply insulin 12 hours before the exam. In these cases, it is recommended to schedule the exam at the first available time.ü Thermal comfort: Keep yourself well wrapped up, especially if the temperature is low, including on the way to the clinic.ü Clothing: It is recommended to wear light clothing, preferably without buttons, zippers and without metal accessories such as: earrings, necklaces, watches, etc.
HOW IS THE EXAM PERFORMED?
After filling out the registration form at the reception desk, the patient will undergo a brief interview to check their data and exam preparation. Then, they will be sent to the preparation room, where blood glucose will be measured. If the blood glucose result is within the limits allowed for the test, a vein in the upper limb will be punctured and maintained with saline.
One dose of the radioactive tracer will be administered through the venous access and the patient should remain at rest for approximately 1 hour.
After resting, the patient will be sent to the examination room. During the entire time of the test, the patient must remain motionless, lying on the device’s gurney.
The examination will begin with computed tomography, a phase of rapid duration, and radiological iodinated contrast may or may not be used.
The average time of this exam is 20 to 30 minutes, and eventually additional late imaging may be required to complement the exam.
The total examination time varies from patient to patient and depends on several factors, from the patient’s height, clinical conditions, dose injected and type of tumor. Therefore, be patient, as we will be carrying out the most appropriate acquisition protocol for each situation.
IMPORTANT NOTES
The suspension of carbohydrates 12 hours before the exam and fasting (except for water) are extremely important to avoid the need for patient recall. Stay tuned.
This test cannot be performed on pregnant women or those suspected of pregnancy.
Patients who are breastfeeding should suspend breastfeeding for 24 hours after the procedure.
