BACKGROUND: Cardiac magnetic resonance (CMR) has developed into a routine examination in many centers in cardiology. However, there is little knowledge about its applicability in outpatients as a diagnostic tool for cardiovascular diseases. We report about the experiences in a high-volume cardiac imaging center and in a "mobile setting" in Germany and provide routinely used examination protocols. METHODS: 8976 patients referred for CMR from cardiologists, internal medicine practices and from general practitioners and 2200 patients examined in a "mobile" system by outpatient cardiologists were included in the study. Indications were as follows: 7672 (69%) examinations for myocardial ischemia and viability, 1313 (12%) for cardiac and pericardial inflammatory disease and cardiac mass, 976 (9%) for detection and quantification of heart valve disease and 466 (4%) for congenital heart disease. 697 (6%) were referred for other indication. Two independent readers performed image analysis of the 8976 patients in our center. RESULTS: Image quality was rated "excellent" in 90.6%, "good" in 8%, "fair" in 1.2% and "poor" in 0.2%. 0.0002% of all examinations were not assessable due to low image quality. Minor complications (temporarily, asymptomatic AV-blockade; mild chest pain and/or dyspnea; nausea) could be observed in 12% and resolved within few minutes. One patient experienced a grand mal seizure due to hyperventilation. 0.9% examinations had to be terminated untimely due to claustrophobia. CONCLUSION: CMR in outpatients is a widely used imaging modality in cardiology in Germany. A large variety of clinical questions may be answered by CMR with excellent image quality and without major complication. With user-adapted protocols, a rapid diagnosis is achieved even in outpatients in a "mobile" setting. Hence, CMR will increase its applicability as a routine imaging tool.
