"A CT scan is primarily used to monitor the progress of treatment for renal cancer."
"A CT scan provides detailed images of the kidneys and surrounding structures, helping to assess the size, location, and extent of the tumor."
"A CT scan is used to directly sample and analyze the cancerous tissue within the kidney."
