In a new large study, researchers have determined that PET/CT scans appear to detect colorectal cancer more frequently than traditional imaging methods. Colorectal cancer typically cannot be detected with ultrasound, MRI, or CT alone until it reaches a considerable size. PET/CT detection is encouraging because it appears to identify colon cancers of smaller sizes, including those that return following treatment.
PET/CT combines the attributes of positron emission tomography (PET) and computed tomography (CT) imaging to create exceptionally detailed 3D images. Not only can the PET/CT identify the location of a mass, but it can also help determine if the cells are cancerous or not. PET/CT is a short and painless procedure. Researchers are hopeful that PET/CT can help find cancers earlier and improve cancer survival rates.
