Review
Various disease processes may affect the ascending thoracic aorta, aortic arch, and/or descending thoracic aorta, including aneurysms, dissections, intramural hematomas, penetrating atherosclerotic ulcers, and aortic transection/rupture. Many of those conditions require surgical intervention for repair. Multiple open and endovascular techniques are used for treatment of thoracic aortic pathology. It is imperative that the cardiothoracic radiologist have a thorough knowledge of the surgical techniques available, the expected postoperative imaging findings, and the complications that may occur to accurately diagnose life-threatening pathology when present, and avoid common pitfalls of misinterpreting normal postoperative findings as pathologic conditions.

The aim was to evaluate the thoracic aorta in different cardiac phases to obtain the correct cardiac phase for measuring the maximum diameter required to predict aortic disease. Cardiac CT was performed on 97 patients for suspected coronary artery disease. The average diameter of ascending (AAD) and descending aorta (DAD) in the plane of pulmonary bifurcation, in the plane of the sinus junction (AAD [STJ] and DAD [STJ]), descending aorta in the plane of the diaphragm (DAD [Dia]), the diameter of the main pulmonary artery (MPAD), distance from the sternum to the spine (S-SD), and distance from the sternum to the ascending aorta (S-AAD) were assessed at 20 different time points in the cardiac cycle. Differences in aortic diameter in different cardiac phases and the correlation between aortic diameter and traditional risk factors were analyzed by the general linear mixed model. The diameter of the thoracic aorta reached the minimum at the phase of 95-0%, and reached the maximum at 30-35%. The maximum values of AAD, AAD (STJ), DAD, DAD (STJ), and DAD (Dia) were 32.51 ± 3.35 mm, 28.86 ± 3.01 mm, 23.46 ± 2.88 mm, 21.85 ± 2.58 mm, and 21.09 ± 2.66 mm, respectively. The maximum values of MPAD/AAD and DAD/AAD (STJ) were 0.8140 ± 0.1029, 0.7623 ± 0.0799, respectively. The diameter of the thoracic aorta varies with the cardiac phase. Analyzing the changes in aortic diameter, which can be done using cardiac CT, could provide a more accurate clinical measurement for predicting aortic disease.

OBJECTIVES
Knowledge of normal aortic diameters is important in the assessment of aortic disease. The aim of this study was to determine normal thoracic aortic diameters.
DESIGN
77 patients undergoing computed tomography of the thorax were studied. The diameter of the thoracic aorta was measured at three levels in the ascending aorta and at three levels in the descending aorta. The diameter was studied in relation to age, sex, weight and height.
RESULTS
We found that aortic diameter is increasing with increasing age. Even sex and BMI influence the aortic diameter but to a lesser extent than age. The upper normal limit for ascending aorta can be calculated with the formula D(mm) = 31 + 0.16*age and for descending aorta with the formula D(mm) = 21 + 0.16*age. Thus a 20-year-old person has an upper normal limit for ascending aorta of 34 mm and an 80-year-old person has a limit of 44 m.
CONCLUSIONS
The thoracic aortic diameter varies with age, sex and body weight and height. The strongest correlation can be seen with age. Age should therefore be taken into consideration when determining whether the thoracic aorta is dilated or not.

Review
The evaluation and diagnosis of thoracic aortic disease using magnetic resonance imaging, including magnetic resonance angiography, is assuming an increasing role in clinical practice. Comparison with other modalities, including computed tomography and echocardiography, is discussed. Newer magnetic resonance imaging techniques, including 3-D breath-hold time-of-flight sequences are highlighted, as well as imaging strategies using standard magnetic resonance imaging techniques. Thoracic aortic disease entities covered include aneurysm, dissection, penetrating ulcers and intramural hematoma, aortitis and infection, tumors, and congenital aortic disease.

Review
Trauma to the thoracic aorta is a significant injury with a high mortality. This mortality is partly due to the delayed recognition of the condition. The increase of motor vehicle accidents and the use of firearms worldwide has resulted in an increase of the incidence of trauma to the thoracic aorta. Certain new developments in diagnosis and management have resulted in traditional methods being questioned. This review analyses current literature and data which we attempt to evaluate.
