Hospital Angeles has a Positron Emission Tomography – Computed Tomography (PET/CT) service, which is able to combine anatomical and functional images. This is a non-invasive diagnostic and research technique that is able to measure abnormal metabolic activity within the body. Combined explorations have demonstrated to provide more accurate diagnostics than two separately performed analyses.

PET-CT uses very small amounts of radioactive material (the most common is glucose) to diagnose and evaluate the degree and extent of diseases, including different types of cancer, heart disease, neurological disorders, and inflammatory processes.

This exploration is not bothersome or painful for the patient. Women must let their physician know if there is any possibility that they are pregnant or if they are breastfeeding, so as to receive indications on the test’s viability. Also let medical staff know what medications you are taking, including vitamins and natural supplements. Also report any other allergies, especially to contrast materials, iodine, and seafood, recent illnesses or other medical problems. If you have diabetes, ask for special instructions to prepare for this exam.

Metallic objects, such as jewelry, eyeglasses, dentures, and hair clips can affect TAC images and must be left at home or taken off prior to the test.

What are some of the common uses of the procedure?

PET and PET/CT are done for:

Oncological indications:

  • Diagnosis of malignant lesions
  • Evaluation of the extent of a disease
  • Patients with biochemical evidence of recurrence
  • Differentiation of residual or recurrent tumors from post-treatment changes
  • Tests on patients with metastasis of unknown primary origin.
  • Planned biopsy of the tumor’s most aggressive part
  • Evaluation of tumoral response to Chemotherapy (QX) and Radiotherapy (RT)

Neurological indications:

  • Epilepsy
  • Brain tumors
  • Cerebrovascular disease
  • Alzheimer’s disease
  • Alterations in movement
  • Schizophrenia
  • Drug addiction

Cardiological indications: Basically, to determine post-heart attack viability
