Overview

CT scan is not a routine test for the diagnosis of deep vein thrombosis (DVT). CT scan venography can be considered for the diagnosis of DVT when ultrasonography is either impractical or non-diagnostic.^[1]

CT

Uses

CT scan might be used for diagnosis of DVT when compression ultrasonography is impractical in cases of excessive swelling, edema, or a leg cast, or when the ultrasound in non-diagnostic.^[1]

CT scan is preferred over contrast venography as there is no need to cannulate the foot veins.

Limitations

CT scan is not done routinely in clinical settings because of certain limitations:

Side effects of IV contrast administration
Expensive modality

Examples
