What size is the minimum you would expect to biopsy under ultrasound guidance using spring loaded biopsy gun?
Most radiologists would be hesitant to biopsy under 5 mm. The fear is that your biopsy would not be representative of the actual lesion if its under 5 mm plus in lesions that small you would not expect early metastases.
The ultrasound shows a small spiculated solid lesion that was malignant on biopsy.
