Cardiovascular examination with 3.0 Tesla magnetic resonance imaging: First 100 cases at Ramathibodi Hospital

Abstract

Background: Cardiovascular magnetic resonance imaging (CMR) has been utilized for diagnosis in various cardiovascular diseases and most of those were performed on a 1.5 Tesla CMR system. Recently, a 3.0 Tesla magnetic resonance imaging system has been introduced into clinical practice, however, the clinical experience on cardiovascular examination using this system is limited. Therefore, the authors' institution has integrated a team for developing a CMR program on this 3.0 Tesla system. Objective: To describe the authors' experience on the 3.0 Tesla CMR system. Material and Method: The data on patients referred to the authors' CMR unit between August 2004 and October 2005 were reviewed. Results: One hundred patients were referred for CMR examination. The mean age was 56 years (2 month - 85 years) and 65 patients were male. The most common indication was to assess coronary artery disease (64 patients). The performed examination was divided into cardiac structure and function assessment (39%), stress testing (23%), coronary magnetic resonance angiography (13%), myocardial viability assessment (12%), magnetic resonance angiography (9%), and flow assessment (4%). Conclusion: The present study highlights that comprehensive assessment of various cardiovascular diseases can be performed on the 3.0 Tesla CMR system.
