Abstract
The thoracic aortic wall is a common site of atherosclerotic plaque in humans. Tools for serial, non-
invasive assessment of these plaques are of value for addressing gaps in our basic understanding of the
biology of plaque rupture and its relationship to atherosclerotic disease progression as well as for moni-
toring response to anti-atherosclerotic interventions in therapeutic clinical trials. Common approaches to
assessment of the wall of the thoracic aorta in vivo are limited. Here we discuss some of the challenges and
limitations encountered by conventional techniques and review a novel approach, transesophageal MRI
(TEMRI). Initial experiences in applying the TEMRI approach to assessment of aortic morphology and
pathology are discussed.
Introduction
Magnetic resonance imaging (MRI) oers several
potential advantages over ultrasound or X-ray
based imaging for demanding applications such as
aortic atherosclerotic plaque imaging. Previous
non-invasive MRI approaches have focused on re-
