What Is PET CT?
PET CT combines the strengths of Positron Emission Tomography (PET) with those of Computed Tomography (CT) to produce superior diagnostic information for patients with cancer, heart disease, and certain neurologic conditions.
PET is a non-invasive, nuclear-medicine procedure that, by visualizing the metabolic processes occurring in the body, is able to detect certain diseases before other imaging modalities can.
By injecting a radioactive tracer into the body and tracking the tracer's distribution, PET is able to identify chemical and physiological changes related to metabolism. This is important since the metabolic changes shown by PET often occur before structural changes develop. CT produces a detailed anatomic map of the body and shows structural abnormalities in minute detail. By combining PET with CT, physicians can exactly localize the sites of an abnormality.
Our physicians are experienced in PET and CT interpretation and are board certified in diagnostic radiology, with additional fellowship training and certification in nuclear medicine.
The Benefits of PET CT
- PET CT can eliminate the need for other invasive procedures and may prevent unnecessary surgical procedures.
- PET CT can show pathological changes before they would be evident on CT or MRI alone.
Some Uses of PET CT
- Evaluate lung nodules
- Stage and restage various tumors, such as lung cancer, melanoma, and lymphoma
- Determine tumor response to radiation or chemotherapy
- Diagnose recurrence of tumor growth after surgical removal
- Decide the best location for biopsy of a suspected tumor
- Help evaluate some patients with dementia
