Positron Emission Tomography (PET) is a type of nuclear medicine scan. A small amount of radioactive isotope is injected o help detect early tumors or metastasis. Computed Tomography (CT) scanning provides detailed images of internal organs.
Combining these two types of imaging techniques accurately displays the location of the tumor/metastasis and aid treatment.
- Diagnosing cancer
- Identifying the site of primary
- Facilitating tumor grading and staging
- Identifying metastasis
- Formulating a treatment plan such as radiation therapy, chemotherapy
- Evaluating patient’s prognosis
- Assessing the effectiveness of treatment
- Monitoring cancer recurrence
PET/CT scan provides information on both the structure and function of cells and tissues in vivo during a single imaging session, providing superior lesion and tumor localization.
