After endovascular abdominal aortic aneurysm repair, life-long follow-up is needed to monitor the effectiveness of exclusion of the aneurysm sac from blood flow. For this reason, aneurysm diameter and the presence of endoleaks is evaluated with CT angiography yearly after Endovascular Aneurysm Repair (EVAR).
The aim of this study is to investigate the value of MRA examinations for the follow-up of these patients. The advantages of MRA with respect to CTA are no use of ionizing radiation, use of less nephrotoxic contrast agents.
The FEAT trial (Follow-up of Endovascular Aneurysm Treatment) is designed as a prospective, single-center, follow-up study. 100 Patients will be enrolled in this study. These patients will undergo additional MRA-examinations the day before EVAR, the day after EVAR, 6 months and 1 year after EVAR. These patients also participate in the conventional CTA follow-up scheme which comprises a pre- and post-operative CTA and a CTA yearly thereafter. Coagulation parameters in the blood will be measured before and 1 year after EVAR.

After endovascular treatment of an abdominal aortic aneurysm, lifelong imaging follow-up is needed to monitor the effectiveness of the treatment. One parameter in this follow-up is endolea...
To investigate the diagnostic performance of whole body magnetic resonance angiography (WB-MRA) using two different magnetic resonance contrast agents.
The study aims at measuring the sensitivity and specificity of a series of imaging signs (recorded by magnetic resonance angiography, vascular tomodensitometry, vascular ultrasonography, r...
The Chinese Cerebral Aneurysms Survey is a continuing prospective study to evaluate the effectiveness of unenhanced, three-dimensional time-of-flight magnetic resonance angiography (3D-TOF...
This is a Phase IV multicenter, open-label study and is being implemented in order to assess diagnostic image quality of MDCTA in subjects undergoing computed tomography angiography (CTA) ...
Untreated thoracoabdominal aortic aneurysms are associated with an exceedingly high mortality rate, and surgery carries a high complication rate. Crawford's classification system of thoracoabdominal a...
Cerebral aneurysm growth often precedes rupture. Definite contributors to aneurysm growth have not been determined even by means of recently developed commercially available computational fluid dynami...
Acute limb ischemia (ALI), a subclass of critical limb ischemia, is a medical emergency. The cause of ALI is usually thrombotic or embolic in nature, and the specific etiology often dictates the appro...
The aim of this study was to investigate radiation dose and image quality of coronary computed tomography (CT) angiography (CCTA) for patients with high heart rate variability (HRv) using 16-cm wide-d...
The aim of this study was to determine the long-term prognostic power of coronary computed tomography angiography (CTA) to predict cardiac death and nonfatal myocardial infarction.
Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in CEREBRAL ANGIOGRAPHY as well as for studies of other vascular structures.
A non-invasive method that uses a CT scanner for capturing images of blood vessels and tissues. A CONTRAST MATERIAL is injected, which helps produce detailed images that aid in diagnosing VASCULAR DISEASES.
An imaging technique using a device which combines TOMOGRAPHY, EMISSION-COMPUTED, SINGLE-PHOTON and TOMOGRAPHY, X-RAY COMPUTED in the same session.
Descriptive anatomy based on three-dimensional imaging (IMAGING, THREE-DIMENSIONAL) of the body, organs, and structures using a series of computer multiplane sections, displayed by transverse, coronal, and sagittal analyses. It is essential to accurate interpretation by the radiologist of such techniques as ultrasonic diagnosis, MAGNETIC RESONANCE IMAGING, and computed tomography (TOMOGRAPHY, X-RAY COMPUTED). (From Lane & Sharfaei, Modern Sectional Anatomy, 1992, Preface)
Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
