general, and in surgery in particular surgery. It shaped the pre treatment and pre 
intervention planning which improved patient selection, treatment selection and 
outcome. Radiology also allowed a more objective evaluation of treatment and 
treatment effects. The same role is played by MRI in the field of angiography. MRI 
angiography hand in hand with CT angiography established an important role as a 
diagnostic modality that is equivalent to the conventional diagnostic angiography.
This geared the interventional angiography towards more therapeutic role. Leaving 
the diagnosis, pretreatment mapping to MRA as a subsequent to the road map defined 
by the MRA. The pre-treatment road mapping had significantly impacted the patient 
outcome. Which is the ultimate goal. MRA has the potential of providing more 
physiological and pathophysiological data over the disease in addition to the 
anatomical information.
This book is divided into three sections. The first section discusses the basics of MRI 
angiography. The first chapter focus mainly on the contrast agents that are mainly 
used in MR angiography with detailed discussion of advantage and limitations of 
different types of contrast. The second chapter is oriented more towards the technical 
consideration that contribute to good quality examination, both the non contrast and 
contrast based sequences from black to bright blood imaging, contrast agents, review 
of clinical application of MRA in different body systems and MR venography.
Section two is covering the advances in the head and neck, brain ischemia imaging. A 
review of the advances in intracranial plaque imaging with High-resolution magnetic 
resonance imaging can identify plaques on the arterial wall as well the plaque 
instability. The future prospective of such technique as well the limitation are 
discussed. Further points of discussion like pathophysiological advantage of MR in 
understanding the mechanism of hemodynamic of brain ischemia, the intracranial 
atherosclerotic stock as well the future challenges and clinical implication of MR in
this field. The quantitative MRA analysis is a new technology that provides non 
invasive method to measure the blood flow in the brain. An over view and 
presentation of technique is covered in the last chapter of this section 
In section three, emphasize the use of MRA in the aortic and peripheral vascular 
disease in pediatric population.
I would like to thank my colleagues who contributed to this work and who invested 
their time in bringing that work to light. We as a team hope that this book will be 
provide added knowledge to the field of radiology. I would like to thank the publisher 
who allows the transfer of this knowledge and make it available as an open source to 
everyone who is interested in the field. Hope you will enjoy reading this book.
