What you will learn in this video:
🔸 Who can undergo PET-CT: Although widely used for cancer patients, PET-CT can also be indicated for neurological diseases, such as Alzheimer's, and some cardiovascular pathologies.
🔸 Frequency of the Exam: The interval between PET-CT exams varies according to the pathology and the doctor's instructions, and can be performed every 3 months, 6 months, or once a year.
🔸 Difference between PET-CT and other imaging exams: PET-CT evaluates the metabolic function of the entire body, while exams such as CT scans and MRI scans evaluate the anatomy of a specific area more thoroughly.
🔸 Exam Duration: PET-CT is safe, but it can take around 3 hours due to preparation time, administration of radioactive material, and image acquisition.
🔸 Contrast Allergy: Patients with allergies to iodinated contrast or kidney problems can undergo PET-CT without issues, as the material used is glucose-based and labeled with radioactive material.
