Using an Imaging Technique Such as Positron Emission Tomography (PET)to

Using an imaging technique such as positron emission tomography (PET) to detect cancer has all the advantages described EXCEPT:

A) the image will be clearer than one derived from X-rays or CAT scans
B) PET data can quantify the level of metabolic activity possessed by the tumor cells which may be useful in determining the rate of tumor growth
C) PET data can predict the next area likely to be invaded by the tumor as it expands or the region to which stray tumor cells may move (metastasize) .
D) PET data can determine the size and shape of the tumor
