If using the 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 up to the magnetic unit. Insert
the hand in the coil, in a vertical position and with the thumb pointing
upwards centering the region examined with respect to the coil.
9 Insert an adequate number of standard cushions
of different thicknesses ( P1 - P3 ) between the coil and limb. This very
important step enables:
- avoidance of undesirable movements;
- facilitated and correct centering of the limb in the coil;
- increased patient's comfort;
- no direct contact between the patient’s skin and the coil, which could
lead to areas of excessive brightness in the images and difficulties with
diagnosis.

interference with insertion of the limb.
