13-16 Probes and Biopsy
When performing biopsy procedures, only use sterile
ultrasound gel that is certified as safe and manage the
ultrasound gel properly to ensure that it does not become a
source of infection.
When performing an operation involving biopsy, wear sterile
gloves.
Image of the biopsy target and the actual position of the
biopsy needle:
Diagnostic ultrasound systems produce tomographic
plane images with information about particular
thicknesses in the thickness direction of the probe.
(That is to say, the information shown in the images
consists of all the information scanned in the
thickness direction of the probe.) Therefore, even
though the biopsy needle appears to have penetrated
the target object in the image, it may not actually have
done so. When the biopsy target is small, dispersion
of the ultrasound beam may lead to the image
deviating from the actual position. Be aware of this.
The target object and biopsy needle appear in the image as
shown in the figures below (for reference only):
