Normal brain and brain tumor: multicomponent apparent diffusion coefficient line scan imaging.

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...
