Depends: The key is an adequate sample of tissue, from the mass. The accuracy comes from the pathologist!
Dr. Michael Gabor
Diagnostic Radiology 33 years experience
Accuracy: Both are highly accurate, 97-99%, in experienced hands. Vacuum assisted may provide a better sample for the pathologist, but standard core can make up for it with more samples. One may be preferred over another in certain particular circumstances.
