Female pelvis: impact of MR imaging on treatment decisions and net cost analysis.

Abstract

To determine the impact of gynecologic magnetic resonance (MR) imaging on treatment decisions and net cost. Sixty-nine consecutive women were referred for 70 pelvic MR imaging examinations. Diagnosis and treatment plans were obtained from referring physicians before and immediately after they were given verbal reports of MR imaging results. Outcome regarding treatment and symptoms was obtained at a mean follow-up of 10.9 months. Of 49 (71%) patients originally recommended for surgery, 36 (73%) either did not undergo surgery or less invasive surgery was performed. In 58 (84%) patients, the treatment performed was that recommended after performance of MR imaging. Symptoms resolved in 57 (83%) patients. Use of MR imaging resulted in an overall savings of $63 per patient ($1,736 per patient originally recommended for surgery). Use of pelvic MR imaging in diagnosis of some gynecologic diseases may alter treatment, decrease the number of invasive surgical procedures performed, and reduce total health care expenditures.
