Abstract
Cardiac magnetic resonance (CMR) is an indispensable second-line tool, next to CT (computed tomography), in the evaluation and follow-up of congenital heart disease in adults and children, as a complement to echocardiography, without the inconvenience of X-rays. This imaging requires a long examination time and good cooperation from the patient to achieve good apnea, or the use of general anesthesia in children under 8 years of age. In this chapter, we summarize the recent advances in CMR sequences, notably the four-dimensional (4D) flow, in software and hardware technologies that allow a wider use, thanks to the simplification of the examination protocols and the decrease of the acquisition time.
