Cardiac magnetic resonance imaging and computed tomography: anatomic fundamentals.

Due to lack of appropriate anatomic visualization using fluoroscopy, radiological scans such as computed tomography and magnetic resonance imaging are increasingly used to provide detailed anatomy of cardiac structures. Furthermore, these imaging modalities are now being used to integrate images with other modalities to navigate catheters in real time on the detailed depicted anatomy. This review details the anatomic fundamentals of these modalities.
