For stereotactic biopsies and MRI-guided biopsies, I use a vacuum-assisted device.

For ultrasound-guided biopsies, I have found both core needles and vacuum devices to be equally successful in my experience, although the scientific literature reports fewer false-negatives with the vacuum-assisted devices. I prefer to use the smaller, less expensive, less scary core needle when possible. If a lesion is very small or subtle on the sonogram, I tend to use the vacuum-assisted device to obtain larger specimens and ensure adequate sampling.

I always use a vacuum assisted core needle device as the vacuum sucks tissue into the needle, which is usually hollow,taking a larger sample that the needle alone could take. More is almost always better for the pathologist to get the diagnosis correct and if there is plenty of tissue, the receptors, and genetic studies such as Mammaprint can also be performed.
