Question

What special tests are done for a pulmonary embolism?

a) D-dimer, CT angiography, ventilation/perfusion scan
b) Troponin levels, echocardiogram, stress test
c) Coagulation panel, chest X-ray, spirometry
d) Cardiac enzymes, arterial blood gas, chest CT scan

Answer 1

The special tests done for a pulmonary embolism include D-dimer, CT angiography, and ventilation/perfusion scan.

Step-by-step explanation:

The special tests done for a pulmonary embolism include:

1. D-dimer: This blood test measures the presence of a substance called D-dimer, which is released when a blood clot dissolves. A high D-dimer level suggests the presence of a blood clot.
2. CT angiography: This imaging test uses a contrast dye and X-rays to create detailed images of the blood vessels in the lungs. It can help detect a pulmonary embolism.
3. Ventilation/perfusion scan: This test involves the injection of a radioactive substance and the inhalation of a radioactive gas. It can help evaluate the blood flow and airflow in the lungs, which can indicate a pulmonary embolism.
