PET-CT is a hybrid of positron emission tomography (PET) and multidetector computed tomography (CT).

PET makes it possible to study, and fundamentally quantify, biochemical and functional processes, while CT studies the morphological or structural aspects. This test consists of administering a drug labeled with a positron-emitting isotope that subsequently detects its radioactive emission, using the PET camera. The magnificent anatomical resolution of a 64-slice multidetector CT, together with a state-of-the-art PET camera, allows for precise anatomical location of the positrons emitted by the drug and, thus, identification of their metabolic changes and pinpointing of the location and extent of tumor lesions.

The main indication of this imaging technique is the study of oncological diseases, although it has shown to be useful in neurological, psychiatric, and cardiological diseases.

At our Center, we work with a state-of-the-art PET-TC and we are one of the first centers to work with this technique in an integrated way. Therefore, PET-CT has become a fundamental technique and it is at the forefront of cancer. It plays an important role in the diagnosis of malignancy, tumor recurrence, and metastatic disease, and in the control of the response to treatment.
