Sažetak
Objective: To present our first experience with cardiac MR imaging, including indications, advantages and pitfalls of the technique. Materials and Methods: Cardiac MR imaging was performed in 50 patients on 3 Tesla scanner after detailed cardiological evaluation and echocardiography. Clinical indications for the exam were listed as Class I and Class II diseases in Consensus Panel report endorsed by The Society for Cardiovascular Magnetic Resonance and The Working Group on Cardiovascular Magnetic Resonance of the European Society of Cardiology in 2004. The scanning techniques that were used included cine TrueFISP imaging in at least three planes with right and left ventricle function calculation ; T1- and T2-weighted sequences for morphological evaluation of myocardium, pericardium and tumor composition ; flow measurement through cardiac valves using phase-contrast angiography ; perfusion MR imaging to detect myocardial ischemia and tumor vascularization ; as well as late-enhancement imaging to depict distribution and extension of the scar tissue within myocardium. Results: Cardiac MR enabled precise evaluation of myocardial disorders, including myocarditis, cardiomyopathies, myocardial viability after infarction, and fibrofatty infiltration of the right ventricle wall in arrhythmogenic right ventricular dysplasia. It helped in differentiation between constrictive pericarditis and restrictive myocardial changes, as well as in staging and pathohistological characterization of cardiac tumors. MR assessment of ventricular function and valvular disease was more reproducible than echocardiographic assessment. Conclusion: The main advantage of cardiac MR is the use of nonionizing radiation ; hence it is important tool in long-term follow-up of patients with congenital heart disease. Contraindications for cardiac MR examination are the same as for MR imaging of other body parts, including implanted cardiac pacemaker/defibrillator, and metallic implants anywhere in the body. Cardiac MR exam is longlasting procedure, where scanning techniques and planes should be chosen according to specific clinical question in order to obtain clinically relevant data.
