Cranial PET CT

What does it consist of?

First the CT is performed and then the PET. The CT allows to obtain images of cuts or sections of the whole body using X-radiation. While the PET allows to evaluate the metabolic activity of the cells present in the organs and tissues of the body by means of the administration of small doses of radioactive radiotracers. Subsequently, a computer joins the images so that they can be seen in three dimensions and thus have as much information as possible about what they want to study.


Before carrying out the test, we will carry out a glycemia control (blood sugar) and, then, we will proceed to the administration of the intravenous contrast. From this moment on, you must remain at rest for approximately one hour so that the contrast is distributed throughout the body evenly. Subsequently, a radiologist technician will accommodate you on the PET-CT stretcher to perform the test. You should lie face up with your head resting on a cushion. Next, the stretcher will move until the area to be studied is in the center of the PET-CT equipment.
