FIG. 6.
a: A catheter (arrow indicates tip) was positioned toward the apex of the heart, imaged with 40 Np (164 ms temporal resolution). b: An injection of gadolinium (arrow) was made into the endocardium and observed with T1-weighted imaging, imaged with 40 Np (164 ms). c: The injection was imaged interactively with 64 Np (262 ms), providing higher SNR and fewer artifacts.
