Members of the Association for Convulsive Therapy were surveyed by mail about use of muscle relaxants and radiologic studies for ECT. One hundred eleven completed responses were received (69%), indicating that 40% routinely acquire pre-ECT spine and skull radiographs taking from 1 to 10 films. From patients receiving more than one course of ECT, 57 pre- and post-ECT pairs of films taken within 1 month of the start and end of a course, respectively, were selected. The films were identified only by age and sex of the patient and were evaluated by a radiologist. A senior psychiatrist reviewed the pre-ECT radiographic reports to determine whether a change in routine ECT procedure was required. Few clinically significant radiologic findings in the pre- or post-ECT films were noted.
