Forearm examinations
Patient Positioning Procedure
DPA Hand/Wrist Coil 2 is recommended for examinations of the forearm
on standard or small-medium size patients.
DPA Foot/Ankle Coil 3 is recommended for examinations of the forearm on
large size patients, when the dimensions of the limb are not compatible
with the DPA Hand/Wrist Coil.
1 Check that there are no obstacles in the patient seat movement area.
2 Ensure that there is no coil in the gantry and that the cavity is totally
free.
3 After releasing the brakes, place the patient's seat in the position
parallel to the magnetic unit. Lock the seat by pressing the rear brake
and at least one of the two front brakes (refer to chapter 6).
4 Place the lumbar support cushion on the seat (refer to chapter 9).
5 Help the patient on to the seat, taking care to instruct the patient to
use exclusively the front part of the seat without attempting to get off
the side.
Place the patient's legs on the padded leg rest.
6 The front and rear shielding collars (optional) must be fixed to the
gantry and opened to the maximum limit, to avoid any type of
interference with insertion of the limb. Always leave the covers fitted
on the gantry.
If using DPA Hand/Wrist coil 2:
7 Insert the coil in the gantry: it clicks into place to confirm correct
positioning.
8 Release the brakes and move the seat so that the arm is aligned with
the gantry opening.
9 Apply (optionally) a magnetic resonance marker on the area being
examined.
W a r n i n g
Users are advised to perform only targeted examinations of forearm
with the O-scan system. An MR marker may be applied to patient's
skin to delineate the area to be examined and verify correct
positioning.
The entire area of the forearm can not be examined in a single
acquisition because the anatomical structure of this area may extend
beyond the O-scan homogeneity region.
