Which tests are commonly used for diagnosing aortic dissection?

Aortic dissection is a serious condition that requires prompt and accurate diagnosis to ensure proper treatment. The commonly used tests for diagnosing this condition include CT angiography and transesophageal echocardiography (TEE).

CT angiography is highly valued for its speed and accuracy, allowing visualization of the blood vessels and the aorta to identify any tears or disruptions in the aortic wall. This imaging technique can quickly assess the extent of the dissection and can be performed rapidly in emergency settings, making it a crucial tool in acute cases.

Transesophageal echocardiography is another useful diagnostic tool, particularly when a more detailed view of the aorta and surrounding structures is necessary. It provides high-resolution images and is especially valuable when patients are unstable or have conditions that limit the effectiveness of other imaging modalities, such as CT.

In contrast, while ultrasound and MRI can provide useful information about vascular structures in some contexts, they are not first-line tests for aortic dissection. X-rays and blood tests do not provide the necessary detail to diagnose this condition accurately, and while the electrocardiogram and nuclear stress test are important for evaluating cardiac function and ischemia, they do not assess the aorta directly for dissection.

Thus, the combination of
