The hospital is the country’s largest cancer centre and the PET-CT scanner plays a crucial role in imaging these patients.

Consultant referral is required and all insurance providers prove direct billing for St James’s.

Information for Patients

A PET/CT scan is an imaging procedure that combines two scanning tests in one examination; a Positron Emission Tomography (PET) scan and a Computed Tomography (CT) scan. A radioactive glucose injection (F-18) is given to a patient and a PET scanner detects the radiation emitted. These images are fused with the CT images to give a detailed anatomical and functional study. Occasionally, the use of oral or intravenous contrast may be necessary.

PET/CT is mainly used for the diagnosis and staging of cancers. It may also be used to evaluate the different causes of dementia, including Alzheimer’s Disease.

Most PET-CT scans can be facilitated within a week of referral however all PET-CTs require pre-approval from your insurance provider which can delay appointments (and is beyond our control). A referral letter from your doctor is required at the time of booking. To make an appointment please see our contacts page.
