Diagnosis of renal cancer may involve several kinds of tests. In addition
to a detailed medical history, physical examination, and laboratory blood
testing, tests may include a computed tomography (CT) scan, ultrasound, magnetic
resonance imaging (MRI), or intravenous pyelography (a
dye and x-ray test of the kidneys). Chest x-ray and bone scan may be used
to detect metastatic disease. Arteriography, a technique
that uses dye in the blood vessels feeding the kidney, may define the extent
of the tumor or help plan surgical treatment.
