Final answer:
The gold standard but time-consuming test of choice for evaluating aortic dissection/aneurysm is a CT angiography (CTA). It involves injecting a contrast dye into the patient's bloodstream and using a computerized tomography (CT) scan to obtain detailed images of the blood vessels. Other imaging modalities like magnetic resonance angiography (MRA) and echocardiography may also be used.
Step-by-step explanation:
The gold standard but time-consuming test of choice for evaluating aortic dissection/aneurysm is a CT angiography (CTA).
This test involves injecting a contrast dye into the patient's bloodstream and then using a computerized tomography (CT) scan to obtain detailed images of the blood vessels in the affected area. CTA can accurately diagnose aortic dissection/aneurysm and provide information about the location, extent, and severity of the condition.
Although CTA is considered the gold standard, other imaging modalities such as magnetic resonance angiography (MRA) and echocardiography may also be used depending on the availability and specific clinical scenario.
