(a) Coronal fast gradient-echo T1-weighted and (b) coronal fast spin-echo T2-weighted images that demonstrate the extensive paramagnetic artifact with the “signal hole” of the tip tungsten ballast (arrowhead), the minor artifacts of the titanium connector (arrow), and the good visibility of the catheter.
