There are two big problems with the idea of a placebo scan:  

1)  switching the "gradient" magnetic fields off and on makes a very loud
noise (like a jackhammer) and perceptible vibration.  To "blind" the patient
to the magnetic field, those would have to be simulated somehow.

2)  the very high DC field is produced by a superconducting magnet which
must stay on constantly.  A test of sensitivity to the DC field might be
devised by having the patient spend time at different distances from the
MRI.  To keep the patient blinded, the test would have to use rooms close to
an MRI that the patient was not previously familiar with and did not have
other clues that the MRI was close.

Given the maze of psychological and physiological interactions operating in
sensitivity, designing should a test would be very tricky.
