16 Probes and Biopsy
The biopsy needle may not have actually entered the target object even
though it appears to have done so in the image. To avoid this, note the
points below:
– Do not rely only on the needle tip in the image. Pay careful attention to
the fact that when the biopsy needle enters the target object or comes
into contact with it, the object should shift slightly.
– Before performing the biopsy, evaluate the size of the object and
confirm whether the biopsy can be carried out.
