Magnetic Resonance Angiography
Unlike traditional angiography which involves placing a tube (catheter) into the body to inject contrast material, MRI is noninvasive. Clinical applications and use of MRA have undergone significant changes with the advances in hardware and software techniques and the use of novel intravascular contrast agents which have allowed a reduction in contrast dose while improving image quality.
