<jats:sec><jats:title>Purpose:</jats:title><jats:p> To evaluate the effects on cost, and number of primary and supplementary neuroradiologic examinations, after introducing MR imaging as the primary modality in the evaluation of the lumbar spine. </jats:p></jats:sec><jats:sec><jats:title>Material and Methods:</jats:title><jats:p> Two 5-month periods were compared: period 1 — before MR; and period 2 — after introduction of a 2nd MR device. In period 1, patients were examined with myelography and/or CT after referral from specialists only, whereas in period 2 both specialists and general practitioners could refer patients for MR imaging. The direct cost (neuroradiologic methods and hospitalization) and indirect cost (sick-leave and estimated loss of production caused by the diagnostic procedure) were estimated. </jats:p></jats:sec><jats:sec><jats:title>Results and Conclusion:</jats:title><jats:p> In period 1, investigations were started in 75 patients (62 myelographies and 13 CT examinations); in period 2, in 227 patients (198 MR, 21 CT, and 8 myelographies). The estimated total cost increased from SEK 825 000 to 1 265 000 (53%), the cost per investigated patient decreasing from 11 000 to 5565 (50%), and the cost of preoperative investigation per operated patient decreasing from 8616 to 5563 (35%). The number of supplementary examinations was unchanged. </jats:p></jats:sec>
