Application of computed tomography angiography in thoracic aortic aneurysm

Aortic Coarctation: Evaluation with Computed Tomography Angiography in Pediatric Patients

Background: Aortic coarctation is a congenital narrowing of the aorta. Computed tomography angiography is used to detect aortic coarctation and determine its extent and severity. Objective: To assess pediatric aortic coarctation by computed tomography (CT) angiography. Material and Methods: This study included eighteen patients (10 males and 8 females) who were clinically diagnosed to have coar...

Measuring of Abdominal Aortic Aneurysm with Three-Dimensional Computed Tomography Reconstruction before Endovascular Aortic Aneurysm Repair

PURPOSE Conventional computed tomography (CT) is the gold standard method for case planning for endovascular aortic aneurysm repair (EVAR). However, aortography with a marking catheter is needed for measuring the actual length of an aneurysm. With advances in imaging technology, a 3-dimensional (3D) workstation can obviate the need for the aortography. The objective of this study was to determi...

Thoracic Aortic Aneurysm

Can coronary computed tomography angiography replace invasive angiography? Coronary computed tomography angiography cannot replace invasive angiography.

O ne million patients undergo invasive coronary angiogra-phy (CA) in the United States every year. 1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for ischemic coronary artery disease (CAD)....

Computed tomography coronary angiography.

Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging. With the last generations of 16- and 64-slice computed tomography and adequate patient preparation (which includes lowering of the heart rat...
