Less Common Tests Used for Deep Vein Thrombosis Diagnosis
Less common tests that your doctor may use to make a deep vein thrombosis diagnosis include:
Magnetic resonance imaging (MRI)
Computed tomography (CT) scan
Genetic testing.
Magnetic Resonance Imaging (MRI)
A magnetic resonance imaging (MRI) uses radio waves to show pictures of organs and structures inside the body. In many cases, an MRI can provide information that would not show up on an x-ray, which is why this test is being used more frequently to diagnose deep vein thrombosis.
Computed Tomography (CT) Scan
A computed tomography (CT) scan is a special type of x-ray that can provide pictures of structures inside the body. This test is rarely used to help make a deep vein thrombosis diagnosis.
Genetic Testing
If your doctor suspects that an inherited disorder is causing the blood clots, your doctor may test for these disorders. Genetic testing is important for people who have repeated blood clots that cannot be linked to any other cause.
Genetic testing is also important for people who have a blood clot in a vein that is in an unusual location such as the liver, kidney, or brain.
