Agreed that it appears stereotactic is a whole different ballgame- I haven't seen any literature with path sniffing the subject, but the whole incorporation of radiation safety, equipment costs, and additional technologists/personnel, I'm inclined to believe this would be probably not worth the hassle. Now about US guided FNA/biopsy in other areas: Is it worth the time to develop? That is perhaps the best question to ask. In some situations I believe it might, it just depends on so many factors, none the least of which is the potential for a referral base. The equipment cost does not appear to be exorbitant. There does seem to be a significant requirement for initial training, especially if one desires some accreditation. Whole clinics are devoted to FNA cytology, so there are definitely viable practices. I have some more technical issues if anyone has any answers: How often are FNA biopsies switched to core specimens? For a non cytopath fellowshipped pathologist, I think most interpretive preferences would be for core tissue. Assuming additional IHC and/or molecular/flow/cytogenetics, I also think core tissue would be preferable, especially in the breast for prognostic information. Does anyone know if current pathology organizations offer ultrasound guided FNA training of superficial lesions pertaining to body sites? Most that I have heard using US guided FNA focus on Thyroid FNA and perhaps other superficial US guided lesions- but I haven't heard of anyone specifically training for breast tissue, other than the articles mentioned. It seems as if there is a distinction between a "superficial" FNA/core biopsy and a deeper area or high-risk (potentially legally) area? It was rightfully brought up that interpretation for what and what-not to biopsy in a breast ultrasound is imperative, but, with rigorous experience (see links below), these parameters are learned. Moreover, documents from the American College of Radiology give guidelines on who can perform an US guided biopsy of breast tissue, indications for biopsy, and provides accreditation.

Obviously this could be desirable from multiple stand points but, does anyone know if this type of accreditation is seemingly "voluntary" or required specifically if you are doing FNA's of the breast? To my knowledge, there is no current additional accreditation required for cytopathologists to do US guided FNAs of the thyroid or head and neck lesions. If I'm wrong about this, please someone enlighten me. As for skin shaves- maybe this could be a possibility be incorporated as well, I'm not sure how often this is being done by pathologists. I see this as less of a option though for a few reasons: Firstly, competition would probably be high-I believe mid-levels as well as physicians can take these skin biopsies with relative ease and have the primary access to patients; whereas US guided techniques, from everything that I have read, is only performed by a licensed physician who has done radiology, surgery, or additional CME training. And although some pathologist may beg to differ, sample quality is likely less of an issue with skin than with lesions that are subcutaneous. Moreover, one of the benefits and possibly reasons for referral to a pathologist is the increased probability for a satisfactorily FNA/Core sampled specimen with faster (and in some cases immediate) feedback than could be given by a radiologist or surgeon alone. I think that is highly relevant and marketable, but there are only rare precedents for this type of pathology practice.
