This detailed anatomy can help to reveal the following information that maybe crucial for a surgeon who maybe planning what technique to use against a cancer:
PET/CT as an imaging tool is the most sophisticated scanner in the world at this moment in time. Fusing functional imaging and anatomical imaging from PET and CT scans respectively; PET/CT facilitates early detection of metabolic abnormalities as small as 4mm or 5mm in size.
