Background: Over the past few years dobutamine stress magnetic resonance (DSMR) has proven its efficacy as an integral part of the diagnosis of coronary artery disease (CAD). Objectives: To present the feasibility and safety of DSMR in Israel. Methods: Thirty patients with suspected or known CAD were studied. DSMR images were acquired during short breathholds in three short axis views and four-, two-, and threechamber views. Patients were examined at rest and during a standard dobutamine-atropine protocol. Regional wall motion was assessed in a 16-segment model and the image quality was evaluated using a four-point scale for the visibility of the endocardial border. Results: In 28 patients (93.4%) DSMR was successfully performed and completed within an average of 55 ± 6 minutes. One patient could not be examined because of claustrophobia and another patient, who was on beta-blockers, did not reach the target heart rate. Image quality was excellent and there was no difference between the rest and stress images in short axis (3.91 ± 0.29 vs. 3.88 ± 0.34, P = 0.13, respectively) and long axis (3.83 ± 0.38 vs. 3.70 ± 0.49, P = 0.09, respectively) views. Segmental intra-observer agreement for wall motion contractility at rest and stress cine images was almost perfect (κ = 0.88, 95% confidence interval = 0.93-0.84, and κ = 0.82, 95% CI = 0.88-0.76) respectively. No serious side effects were observed during DSMR. Conclusion: The present study confirms the feasibility, safety and excellent image quality of DSMR for the diagnosis of coronary artery diseases.
