BIOPSY METHODS
28
Stereo
On the Siemens MAMMOMAT 3000 Nova, there is the possibility
of connecting up a stereo biopsy attachment. With the aid of
this stereo attachment, biopsies can be performed both with fine
needle and core-gun technique. Instructions on how the attach-
ment is mounted and used is described in the separate Operating
Instructions “Stereotactic Biopsy Attachment”. The following are
some advices on how the examination can be made easier for the
patient.
Inform the patient about the procedure. Explain that the
examination can take time (at least 20 minutes) and that she must
sit still subject to compression the whole time. Explain that the
greatest source of unpleasantness is not the actual needle-puncture
but rather the sitting position. This procedure can also be carried
out with the patient recumbent.
Show the patient the angular movement and how the cassette
is moved.
Ask the patient to sit in the examination chair. The chair must
be height-adjustable and be provided with lockable wheels and
adjustable arm supports. Start from as high a level as possible of
the chair (facilitates the working position). A foot ring on the
chair, or a footstool, improves the sitting position. Ask the patient
to check that she is sitting comfortably.
