Advancements in medical imaging technology over recent years have revolutionised the management and treatment of all aspects of health care. Computed tomography and magnetic resonance imaging have led to the development of reconstruction software that allows internal bodily structures to be easily visualised in 3D. These developments have led to improved surgical planning and treatment. The assessment of abdominal aortic aneurysms (AAA) has benefited greatly from these advancements. There is currently much debate as when to surgically repair these life-threatening dilations of the aorta and 3D reconstructions of AAAs have led to many new diagnostic tools and rupture-prediction indices. This book explores recent developments in this area.
