Assessment Of Aortic Pathology Research Articles

Prospects of the Magnetic Resonance Imaging Method for Assessing the Bioelastic Function of the Aortic Wall

The distinct growth of cardiovascular diseases (CVD) and aortic diseases in the world requires accurate diagnostic methods for their early prediction. In modern research, more and more attention is paid to biomechanics and numerical models of accurate quantitative calculations. The assessment of aortic pathology using magnetic resonance imaging (MRI) acquires great clinical significance, since it makes it possible to simultaneously assess the anatomical topography and physical properties of the aorta. A broad study of changing biomechanical processes will complement the existing ideas about the basics of aneurysm formation and aortic dissection. MRI is a modern non-invasive method that provides the necessary data to as-sess the physical properties of the wall and directional flows in the aorta.

Aortic 4D flow: quantifying the effects of contrast and field strength at 1.5 T, 3T and 7T

Background 4D flow is a promising new method for assessment of aortic pathology, but is limited by signal-to-noise ratio (SNR) leading to long acquisition times. Higher field strength may prove a solution. SNR in aortic 4D flow increases at 3T versus 1.5T (Strecker et al, JMRI 2012) and further by adding a contrast agent (Bock et al, MRM 2010). This work extends this comparison to human 7 Tesla and quantifies the field strength dependent effects of contrast agents.

Assessment of Aortic Pathology and Peripheral Arterial Disease Using Multidetector Computed Tomographic Angiography

The development of multidetector computed tomography represents a remarkable diagnostic advancement because this imaging modality has been widely used in the evaluation of the cardiovascular system. With scanner-adjusted image acquisition and contrast medium administration, multidetector computed tomographic angiography provides a cost-effective and accurate imaging assessment in patients with aortic pathologies or peripheral arterial occlusive disease. Multidetector computed tomographic angiography is associated with several advantages, including high image spatial resolution and rapid imaging acquisition speed. This diagnostic methodology allows accurate detection of a variety of intravascular lesions in the carotid artery, thoracic and abdominal aorta, renal arteries, and peripheral arterial systems. This article provides an overview of multidetector computed tomographic angiography in the assessment of arterial disease and reviews current literature about this diagnostic technology in the evaluation of aortic and peripheral arterial pathologies.

Transesophageal echocardiography in the assessment of aortic pathology

Transesophageal echocardiography is an excellent method for diagnosing aortic pathology, especially dissection, and has replaced transthoracic echocardiography for this purpose. Advantages of the transesophageal method are its speed, portability, and accuracy. Disadvantages are the requirements of operator skill and patient sedation, as well as poor visualization of the distal 2-3 cm of the ascending aorta. Transesophageal echocardiography may become the initial diagnostic procedure of choice when acute dissection is suspected.
