For Physicians
IMAGING
The thoracic aortic anatomy is followed with serial imaging studies-usually CT scans or MRI-so that progression of disease in the remaining aortic segments is detected early so that additional interventions, if needed, can be performed in a timely fashion. The Center provides regular updates on patients' progress to their primary physicians, who continue to manage their other medical conditions.
A variety of modalities are available to image the thoracic aorta. Most patients are initially evaluated and followed with:
- Helical CT (computed tomography) scans, which provide excellent resolution of aortic pathology. For those with complex aortic anatomy, we perform a 3-dimensional reconstruction of the CT scan data, which permits images of the aorta to be displayed in multiple planes, and increases the accuracy of aneurysm measurement.
- MRI (magnetic resonance imaging) is used frequently as well, particularly in patients with pre-existing renal failure, and also permits imaging in multiple planes.
- MRA (magnetic resonance angiography) is used when definition of branch vessel anatomy is required. Traditional contrast angiography is performed in certain cases, particularly for pre-operative evaluation. In cases in which the aortic root is dilated or aortic insufficiency is present.
- Transesophageal echocardiography may be performed to define the anatomy of the valve and ascending aorta.
