Case 230: Congenital Inguinal Herniation of the Left Ureter (Extraperitoneal Form).

abstract：:In an effort to minimize distortion and artifacts on magnetic resonance images obtained with electrocardiographic (ECG) gating, the authors tested the use of ECG electrodes and leads made of carbon fiber. These materials caused no image degradation and, because the leads were reinforced with plastic, were less vulnera...
