Abstract

Based on current evidence, there are numerous clinical advantages of CMR, and in the diagnosis of ARVC/D. CMR is regarded as the gold-standard imaging test for evaluation of the right ventricle. CMR has the ability to image the heart in any plane, has excellent blood pool to tissue contrast, is highly sensitive for detecting subtle wall motion abnormalities, and has proven reproducibility. Additionally, MRI is noninvasive, does not expose the patient to ionizing radiation, and can be done without contrast while effectively evaluating chamber size, ventricular function, and wall motion abnormalities. However, even the ideal imaging modality requires a skill and knowledge in order to realize its diagnostic potential. Similar to any imaging modality, appropriate CMR acquisition is essential for accurate diagnosis. Unfortunately, we frequently have patients who are not ideal for scanning. In this chapter, we review tricks and tips for scanning and obtaining successful images in "difficult" patients, with emphasis on patients with arrhythmias that preclude appropriate ECG gating, those who cannot hold their breath appropriately, and patients with cardiac pacemakers.
