Is there a reason why most of the images show a biopsy or FNA from the caudal aspect of the probe? Can you list the advantages or is this a matter of preference.

Good question randy its
Good question randy its just a preference. I am right handed and I like to see the needle come into the screen at the upper rioght 1 o’clock position. The probe marker is pointing to the head of the patient and the GE label on my machine will be to the left as I guide my needle along the right side of the probe, opposite the probe marker. I could rotate the probe 180 degrees and come in along the marker and the GE label but I like to keep the orientation the same way as when I scan so I come in from the right of the probe with the label toward the head. Others come in the left side of the screen but my brain doesn’t like that lol:)

Thanks Eric. Makes perfect
Thanks Eric. Makes perfect sense. I am right handed – so I think I will try it your way.
A follow up question. Can you tell me what sort of needles you use for FNA and then core biopsies. I would appreciate the brand of the needles and the length you stock.

FNA woodpecker technique
FNA woodpecker technique 25g for spleen and lipidotic liver, 22 g for everythign else.
see my youtube on this:
https://www.youtube.com/watch?v=–lNj-7MUG4
Core bx I use the springloaded monopty by Bard http://sonopath.com/resources/cool-ultrasound-gear/what-do-we-use-obtaining-ultrasound-guided-biopsies
18 g 2.2 cm cut for dogs < 20# 1.2 cm cut for cats, 16g for 20-50# and 14 g for > 50# but depends on the tissue.
Fragile mushy livers I go higher on the gauge toward 18, cah and fibrotic livers I go lower toward 14 as scars dont bleed. Lower gauge for LN….”Gauge” your battles 🙂
core bx and lower gauge for more structural pathology (CAH, GN, nephrosis. lymphadenitis vs lymphoma) higher gauge or fna for cellular pathology (lsa, mct carcinoma)
