Diagnosing a Blood Clot and a Pulmonary Embolism

According to the Mayo Clinic, there are specific tests to detect blood clots in the veins. These include:

• D-dimer blood test
• Ultrasound
• Venography
• Magnetic resonance imaging (MRI)
• Blood tests

If the doctor suspects a pulmonary embolism, there are a few tests that can help clarify that diagnosis:

• Chest X-ray
• Lung scan
• Pulmonary angiogram
• Spiral (helical) computerized tomography (CT) scan
