Contrast enhanced MR angiography

Contrast enhanced MR angiography is a technique involving 3D spoiled gradient-echo (GE) sequences, with administration of Gd-based contrast. It can be utilised to assess vascular structures of almost any part of the body. It's key features are as follows:

  • T1- weighted spoiled gradient-echo sequence (flip angle 25° - 50° allows  T1-weighting)
  • central k-space acquisition corresponding to arterial phase of the study maximizes preferential visualization of arteries
  • use of Gd-based contrast to shorten T1-interval of the blood which appears bright as a result
