Abstract

In this chapter, we describe in detail our clinical CMR protocol for patients with known or suspected ARVC/D and compare it to the CMR protocols utilized by other ARVC/D centers. Our predominant sequence on 1.5-T magnet for assessment of the global and regional RV and LV function is a balanced-state-free precession sequence, or bSSFP. Rarely, we may need to utilize the gradient echo (GRE)-based cine images, when significant valvular regurgitation is suggested or when the patient has a pacemaker/ICD. SSFP images are the basis for RV functional and structural assessment. Use of the dark blood T1-weighted sequences and delayed gadolinium enhancement assist in evaluation of the structural RV and LV abnormalities, such as fibrofatty infiltration and inflammation. Our ARVC/D protocol is fairly standardized and provides structural and functional data for both ventricles since LV involvement is an important clinical and prognostic factor in this disorder. Finally, we discuss some methodological aspects of RV volumetric measurements and provide recommendations for repeatable quantitation of RV volume.
