Abdominal aortic aneurysm | Radiology Reference Article - Radiopaedia.org
2024年3月15日 · CT angiography (CTA) is considered the gold standard for evaluation but exposes patients to high radiation doses. It is excellent for preoperative planning as it accurately delineates the size and shape of the AAA and its relationship …
Thoracic aortic aneurysm - Radiopaedia.org
Thoracic aortic aneurysms are a type of thoraco-abdominal aneurysms and are relatively uncommon compared to abdominal aortic aneurysms. There is a wide range of causes, and the ascending aorta is the segment most commonly affected. Both CT-angiography and MR-angiography are the modalities of choice to image this condition.
CT and MRI Assessment of the Aortic Root and Ascending Aorta
2013年5月23日 · Three-dimensional datasets acquired using CT angiography (CTA) and MR angiography (MRA) are in many ways ideally suited to meet these demands. Generating clinically relevant measurements requires high-quality images, a consistent strategy for radiologic aortic evaluation, and an understanding of how those measurements impact clinical decisions.
Chest CT Angiography for Acute Aortic Pathologic Conditions: …
2021年3月1日 · Chest CT angiography (CTA) plays a key role in the diagnosis and management of patients with a suspected acute aortic pathologic condition, a life-threatening emergency (1). Acute aortic diseases have high morbidity and mortality, with 50% of patients dying from untreated type A aortic dissection in the first week (2).
CT and MRI in Diseases of the Aorta - AJR
This review focuses on the role of CT and MRI in the diagnosis, follow-up, and surgical planning of aortic aneurysms and acute aortic syndromes, including aortic dissection, intramural hematoma, and penetrating aortic ulcer.
Abdominal CT: aortic aneurysm • LITFL • Radiology Library
2024年6月3日 · An abdominal aortic aneurysm (AAA) is an abnormal bulging of the abdominal aorta which can pose a risk for bursting (i.e., rupture) over time. A rupturing abdominal aortic aneurysm is a vascular surgical emergency and requires urgent diagnosis with clear communication of the findings to direct patient care.
Imaging of Aortic Aneurysms and Dissection: CT and MRI
There are numerous approaches to the diagnosis of aortic aneurysms and aortic dissection. Echocardiography, computed tomography (CT), and magnetic resonance imaging (MRI) have enthusiastic proponents promoting each technique, which to some extent obscures the real value of each technique.
Imaging Thoracic Aortic Aneurysm - PMC - PubMed Central (PMC)
Cross-sectional imaging (CTA and MRA) plays a central role in management of patients with thoracic aortic aneurysm. Maximal aortic diameter is the primary metric used to estimate risk and determine the need for surgical repair, although diameter measurement are subject to error related to image artifact and measurement technique.
Multidetector CT of Thoracic Aortic Aneurysms | RadioGraphics
2009年3月1日 · Multidetector computed tomographic (CT) angiography allows the comprehensive evaluation of TAAs in terms of morphologic features and extent, presence of thrombus, relationship to adjacent structures and branches, and signs of impending or acute rupture, and is routinely used in this setting.
ACC/AHA Guidelines for Aortic Disease - StatPearls - NCBI Bookshelf
2024年6月8日 · Gated chest CT is the first-line imaging modality to assess acute aortic syndrome. Family Screening. A multigenerational family history is indicated for patients with aortic root or ascending aorta aneurysms or aortic dissection. Patients at risk for hereditary thoracic aortic disease should undergo genetic testing for known aortopathy genes.
