direction of the probe. (That is to say, the information shown in
the images consist all the information scanned in the thickness
direction of the probe.) So, even though the biopsy needle
appears to have penetrated the target object in the image, it may
not actually have done so. When the target for biopsy is small,
dispersion of the ultrasound beam may lead to image deviate
from the actual position. Pay attention to this.
If the target object and the biopsy needle appear in the image as
shown in the figures below (For reference only):
The biopsy needle appears to reach the target object in the image
Dispersion of the ultrasound beam
The biopsy needle may not have actually entered the target object
even though it appears to have done so on the image. To avoid
this problem, note points below:
Do not rely only on the needle tip on the image. Pay careful
attention to that, when the biopsy needle comes into the
target object or contacts with it, the object should shift
slightly.
Before you perform the biopsy, please evaluate the size of the
object and confirm if the biopsy can be carried out.
