Whole-Body Computed Tomography for Oncologic Staging and Disease Surveillance
This radiation-based X-ray computed tomography exam captures high-resolution cross-sectional images of every major anatomical structure across the entire body to identify both primary and metastatic cancerous lesions. For oncologic care teams, this non-contrast whole-body CT protocol is used to complete initial cancer staging to map the full extent of disease spread, track tumor response to chemotherapy, immunotherapy, or radiation treatments, and detect new or recurrent cancer sites during routine long-term surveillance visits. Patients do not need to fast before this exam, and no intravenous contrast is administered, though they will be asked to remove all metal clothing, jewelry, and accessories prior to scanning to prevent image distortion.
This non-contrast, radiation-based whole-body computed tomography scan evaluates all major body regions for primary and metastatic cancer lesions to support oncologic staging, treatment response assessment, and long-term disease surveillance.
