This ability totally redefines the term “early detection,” of course. Other imaging systems such as MRI, x-ray and ultrasound depend on there being some macro – level change occurring within the body, but PET/CT virtually has eliminated the concept of exploratory surgery. It provides full – body imaging, or can be directed to a single area of the body. In either case, PET/CT produces a three – dimensional image that assists in diagnosing either primary or secondary disease with pinpoint accuracy.
There are several advantages to PET/CT disease diagnosis other than the obvious benefit of detection that now is much earlier than it ever could be prior to the widespread use of PET/CT imaging technology. In the face of continually rising costs, PET/CT has the ability to replace multiple medical procedures and assessments with a single PET/CT scan. PET/CT allows the diagnostician to evaluate all organ systems at one time, which is of particular value in the diagnosis and treatment of cancer. In cancer cases, PET/CT also provides information on internal changes, yielding insight into how an individual patient is responding to cancer treatments much earlier than other types of imaging systems can provide informative results. It also identifies optimal locations for testing with biopsy.
