Steady-state free precession (SSFP) four-chamber image of heart in 37-year-old woman provides good anatomic information about cardiac morphology and can be used for functional assessment of cardiac motion and is typically acquired in multiple planes including two-, three-, and four-chamber cardiac planes. This is bright-blood imaging sequence with good endocardial-to-blood pool contrast ratio. In this patient, there is round mass in right atrioventricular groove that is isointense to myocardium of SSFP images, which have both T1 and T2 weighting that on subsequent imaging was confirmed to represent paraganglioma of atrioventricular groove.
