PET/CT is the most powerful tool in the detection of disease and in the staging of cancer.

PET (Positron Emmission Tomography) is a non-invasive procedure that helps to detect changes in cell activity.

CT (Computed Tomography) is a highly detailed scan of the internal anatomy, which reveals the location, size and shape of the diseased cellular activity.

By the injection of a radiotracer prior to the scan and the fusion of the PET and CT images, a trained Radiologist will be able to identify and characterize abnormal molecular activity that will aid in the patient’s therapeutic management course.
