7/31/2023 0 Comments Normal aortic arch diameter6, 7 An aortic aneurysm is defined as a permanent localized dilation of the aorta, with at least a 50% increase in diameter compared with the normal expected diameter. Thoracic aortic aneurysm is an uncommon incidental finding in patients undergoing LDCT screening for lung cancer, occurring in 0.2% to 0.4%. 5Īlthough there are guidelines for reporting and management of pulmonary nodules encountered on screening CT, there are as yet no existing guidelines for the reporting and management of incidental findings. is the recent decision by the Center for Medicare and Medicaid Services to approve funding of lung cancer screening. 2- 4 Equally important for increasing lung cancer screening in the U.S. 1 Recent endorsements for LDCT lung cancer screening from the United States Preventive Services Task Force, and a number of medical and surgical societies, are increasing acceptance of LDCT as a screening tool by both patients and health care providers. doi: 10.1007/s1055-y.Screening for lung cancer with low–dose CT (LDCT) has been shown to reduce deaths from lung cancer by 20%. Contrast-enhanced magnetic resonance angiography of the great arteries in patients with congenital heart disease: an accurate tool for planning catheter-guided interventions.

Coarctation of the aorta: comparison of aortic dimensions between conventional MR imaging, 3D MR angiography, and conventional angiography. Godart F, Labrot G, Devos P, McFadden E, Rey C, Beregi JP.

Aortic stiffness and diameter predict progressive aortic dilatation in patients with Marfan syndrome. Nollen GJ, Groenink M, Tijssen JG, Wall EE Van Der, Mulder BJ. Configuration of the ascending aorta in patients with bicuspid and tricuspid aortic valve disease undergoing aortic valve replacement with or without reduction aortoplasty. ![]() These data may serve for making the diagnosis of pediatric arch anomalies, assessing the need for treatment and planning interventions.īauer M, Gliech V, Siniawski H, Hetzer R. This study provides normative values for aortic diameters in children measured by CE-CMRA. Normative diameters were (0.57 + 19.37*BSA0.5) mm for the aortic sinus, (-3.52 + 18.66*BSA0.5) mm for the first segment of the aortic arch, (-3.37 + 16.52*BSA0.5) mm for the isthmic region and (-1.27 + 9.89*BSA0.5) mm for the descending aorta at the level of the diaphragm. Regression analysis of diameters in relation to BSA demonstrated linear relationship between the cross-sectional aortic diameters and the square root of BSA (BSA0.5). Aortic diameters were measured at nine standardized sites on oblique maximum-intensity projection (MIP) images. The median age was 9 years (range 2 - 20 years), weight 30 kg (range 12 - 75 kg), height 131 cm (range 81 - 184 cm), body surface area (BSA) 1.05 m2 (range 0.52-1.9 m2). We sought to establish normal values for the diameters of the thoracic aorta and reference curves related to body growth in children using CE-CMRA.ĬE-CMRA was performed in 53 children without cardiovascular disease. Contrast-enhanced CMR angiography (CE-CMRA) is being increasingly used for diagnosing aortic arch anomalies, planning interventions and follow-up assessment.
