When is this exam indicated?
Centering CT is indicated for all sites of disease to be subjected to radiation therapy.
How is it performed?
Centering CT is acquired by positioning the patient in the same manner in which he or she will need to be positioned during radiation treatment, through the use of customized immobilization systems. Depending on the site to be treated and the clinical indications, it can be performed with or without contrast medium. In some cases, this examination may possibly be combined with additional procedures such as PET or MRI to obtain more information at the treatment planning stage.
Centering CT is a simple and short examination for which there are no particular contraindications.
