A PET Scan can detect cancers in their earliest stages. PET/CT images the metabolic activity or function of the body’s tissues, often identifying cancerous sites before they can be detected by conventional anatomic techniques such as CT or MR. PET/CT is a powerful tool in the assessment of non-specific findings detected on x-ray, CT or MRI. PET/CT is able to more accurately characterize findings, leading to more appropriate management. Consequently, unnecessary procedures or tests that present risk and cost to the patient can be reliably avoided in many instances. PET scanning also aids in surgical planning and radiation therapy planning, leading to more focused interventions at lower risk and cost to the patient while providing a higher likelihood of success.
